I noticed a few people asking about the capacitors. There are two 47uF 16volts, and one 10uF 63volt. Make sure you get caps with a temperature rating of 105 degrees Celsius. Get quality caps so you don’t have to do this again soon. Panasonic, Rubycon, Nichicon are quality brand names. And if you see corrosion under those caps from the leakage, make sure all of that gets cleaned off. A qtip and alcohol works. Be careful so you don’t damage any of the very thin traces (the places the current flows) and also make sure they have good continuity on both ends of the trace if you find yours look damaged. Quite common under leaky caps and just replacing the caps will not solve all of your problems.
When soldering you need to get the iron onto the surfaces to be soldered then, once they have time to heat up, feed the solder into the joint. Hitting the solder first burns off the flux and by the time the joint is joining the party you're already fighting surface oxidation in your bead of solder.
Thank you! Now that I think about it, I know someone with a fox. That one is a manual but the idle bounces around. Maybe I can get his car on the channel and get a part 2.

Modern trucks, even those classified under OBD-I (On-Board Diagnostics), do not use carburetors but rather electronic fuel injection systems (EFI). In these vehicles, similar principles apply but with different mechanisms: Idle Air Control (IAC) Valve: Instead of an automatic choke, modern engines use an IAC valve that regulates airflow into the intake manifold during idle conditions. This valve adjusts based on engine temperature and other parameters. Cold Start Enrichment: When you start a modern truck in cold conditions, the engine control unit (ECU) detects low temperatures through various sensors. It then commands the IAC valve to allow more air into the system temporarily while also adjusting fuel delivery for optimal performance. Just like with carbureted engines, this results in a higher idle speed immediately after starting until the engine reaches its normal operating temperature. Once warmed up, the IAC valve reduces airflow back to standard levels, stabilizing idle speed. In summary, while both carbureted trucks and modern fuel-injected trucks exhibit high idling speeds during cold starts due to their respective mechanisms designed for enriching fuel mixtures or adjusting airflow, they operate using fundamentally different technologies. Understanding these differences helps clarify why such behaviors are observed across various types of vehicles.
That’s a great question! Distributor cap, plugs, and wires had all been recently replaced. I had been diagnosing the two idle issues and shift issues independently and getting nowhere. I described the problems to my uncle who is a retired mechanic and owns a few of these trucks. He pointed me to the ECM.
@@Blackford86 no transmission issues, I’ve been lucky so far. It shifted so strangely before the ECM fix I was concerned I’d be in there soon but all of the strange shifting behaviors went away after the repair. I do need to do a fluid/filter on it at some point. This truck only gets about 10 miles a month put on it.
I had the same issue. I replaced the capacitors twice. The first time worked okay for a while but the original capacitors leaked and corroded the board. I finally bought a new ecu and it ran better than ever. It wasn't that expensive either.
@@erice6652 I figured this was worth a try for a truck that gets used very little. Since replacing the capacitors it’s better but still not perfect. This truck is probably going to get a different engine someday so I’ll get it running great when that happens.
750rpm standard, sometimes that so called idle screw on throttle body might have been adjusted and might need some correction in order to allow the iac to do it's job.
Thanks for sharing, I’ll have to check that out. This fix improved the condition but it didn’t solve everything. It does idle better now and shifting gears is night and day.
Good video, am saving for a future project. Interestingly, I have been spinning about the extremely hard shifts that would mysteriously go away. Very long story, no real guidance in following the codes I pulled. There is still an issue and your solution will be on my future attempts to correct the issue. In the meantime, I also figured out that in troubleshooting my issue I finally read in a forum that the codes, even though cleared using my reader, were still having an effect in the truck UNTIL I disconnected the battery. It is a 94 f150 5.0, a truck used temporarily and for plowing. What triggers it back into hard shifting is going over 60mph! After confirming this condition, my plan is to keep it under 60, and so far so good, driving for weeks now!!! The battery disconnect was really causing inconsistent "results" in repair attempts. I also noticed that in your case shifting was smooth after the capacitor replacement AND a battery disconnect.
my 76 360 FE had a rough idle, a miss and off idle stumble. 1. i replaced all the vac hoses-it got lil better 2. replaced all the spark plugs and wires were new-that did nothing 4. replaced gas tank and fuel sender and carb fuel filter and added a pre pump see thru filter- this helped alot 3. rebuilt the carb before the other fuel stuff -that temporaily helped but tank was rusty and there was 2-3 vac leaks on carb shaft and below carb 5.

my 90 ford has been the most reliable vehicle i ever owned.back when ford still give a crap about quality & dependability.sadly, they are gone forever from ford products.replaced by greed & short term junk.
I just changed my idle air control on my '90 F350 5.8 due to the engine dying with the AC on. I found the IAC was very clean and the shaft moving freely. BUT, the solenoid was not working . Problem solved. I suspect it can also account for unnecessary high idle too. I suggest you replace it and see or at least test the solenoid.
@@trustme7731 Thanks for sharing. I unplugged mine while it was running and the RPM dropped way down so I took that as it’s working but still wonder about it.
Here is the set I bought off eBay. www.ebay.com/itm/285079885645?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=xoYngVoKTuO&sssrc=4429486&ssuid=jmlzeliuqek&var=&widget_ver=artemis&media=COPY I know they are more than $1, I don’t live near any electronics supply stores so I had to pay more to order them online.
The ecu's for these Ford's are for their exact model. 4.9L with manual won't fit a 4.9 with an auto and sure won't work for a 5.0 or 5.8. Every transmission and engine combo had a different ecu
If you haven’t done so already, you NEED to get back into that module and replace the other two caps. Additionally, the leakage from the one you did replace has damaged the small traces near it. Those will need to be checked for continuity and may need jumpers from the end points if the traces are that bad. That is how you fix traces that are that small, with wire jumpers. I could see they looked corroded to a point where you probably have lost some vehicle component controls from that ecu. That leakage becomes an acid that eats the copper traces away. They turn dark like yours did when that happens. As far as your soldering, when you bring the soldering iron to the pad and the lead, leave the soldering iron on it for a few seconds longer with the solder. Wait for the solder to completely melt and leave the iron there for a few seconds more so the pad and the lead get hot enough to allow the solder to attach to both. Don’t continue to add more solder. Once the solder melts on both, it will form a cone. When you kept putting more solder on the spot and kept pulling the gun away, that’s why it beaded up on you. But anyway, once you are in that thing, always replace all of those electrolytic capacitors. They have likely developed a high ESR value after this much time, and that is not something you can visually check for. Additionally, if they start leaking too, you will have more damage to the traces. 🙂
@@HD24680 Great advice, thank you! I'll be doing more work on the truck this fall and plan to get back into the ECU. Thanks for the soldering tips, I do very little board soldering, mostly wires.
I have a 1989 f350 that is having similar issues I have to drive it like a manual to get it to shift and after driving 25 and stopping at a red light or stop sign it wants to surge. Any thoughts as if it could be this same issue?
It could be contributing to the problem but if yours is not shifting at all without manually shifting I’d say you probably have another issue. Mine would shift on its own with no stalling or surging, but always too early upshift and too late downshift. It would quickly get to overdrive even at low speeds and wouldn’t downshift until I basically floored it.
My 91 f150 inline 6 is idling high at 1000 rpm and after revving it goes right back down to that. And it jumps down then right back up. I was told to check the IAC valve because it might be bad. Not sure how to go about it. Any tips?
I checked the IAC first on my truck. What you can do is start up the truck and while it’s running unplug the wire harness to the IAC. If the idle drops super low and/or the engine stalls, the IAC is working. If there’s no change it’s probably bad.
These are the ones I bought. Price has gone up a bit. www.ebay.com/itm/285196645181?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=xoYngVoKTuO&sssrc=4521899&ssuid=jmlzeliuqek&var=&widget_ver=artemis&media=COPY

I absolutely agree. If you check out my other videos I have a series on my 2010 Expedition daily driver I’ve put a lot of miles and $$$ into to avoid buying anything new!
I feel dumb asking a question like mine. I used to mechanic, but never worked on electronics. I loaned my explorer to a kid and he brings it back a month later with it out of oil, did have maybe a pint in it. We replaced the oil and there is no knocking sounds, no anything out of the ordinary except for the pressure is very low. It starts and runs well, it is not a high mileage rig and it is a 95 model with the 4.0 engine. Is the ECM have anything to do with oil pressure readings
No problem with asking questions, it’s how we all learn! Diagnostically I’d expect the low oil pressure is due to the wear the engine endured with low oil. Must not have caused enough damage to create any knocks or noises. I’m not entirely familiar with how the ECM integrates to the oil pressure system in that vehicle. I’m guessing it may only place a diagnostic code or put the vehicle in limp mode if it sees a problem. That is totally a guess, it may not be connected at all. I wouldn’t expect the ECM is causing the low oil pressure reading, If the oil was that low I bet the bearings are super worn and life expectancy of that engine would be very low.
If it was run low on oil, the low oil pressure is from worn crank\main bearings. You said a pint was in it? Is that what showed on dipstick, or what drained out upon doing oil change? If only a pint came out of oil pan, that engine is a perfect boat anchor candidate right now. I'd say the kid was probably beating on this thing too but idk for sure? Was there an oil consumption problem previously(before getting loaned out)? If I were you and the rest of this vehicle is in great condition, start looking for a nice lower mileage motor from a junkyard online right now. Probably $3 -4k should get you an engine & installation r&r. Unless you & a friend can tackle the project. It's not hard but you do need an engine lift, jack, j.stands & of course hand tools - sockets, wrenches, etc(really don't need any specialty tools or a lift tho). I know a guy w\ an Explorer(exploder) who never changed his oil, nor even checked it for that matter. So the thing smoked itself on a thruway trip & seized up due to lack of any oil. I gave my buddy a hand putting a junkyard engine into it. Iirc, i think it was all done for under $3k (~$2200engine + $650labor + fluids), which is not too bad compared to buying a new one @ $500 --$1000/per month! 😮😢👍🏻🛠️🔧🔩🤔🤷🏻♂️🚗🚐🚦⛽🛢️🚧
Um why did you not change out the other two caps when you were already in there. It was obvious the other two were leaking as well. You had it out and open. It was not like its a hard fix. I guess I just dont understand why you did not do it.
Gonna blow a head gasket with you temp that high. I have a 1990 and a 1991 and they run NOWHERE near the middle. And yours is showing .75😮.. hopefully you just have a bad sensor. On my trucks at full temperature I'm 1/4
Never even noticed it. It doesn’t normally run that high. Thanks for pointing that out, I’ll give it a look over before I drive it next. This one doesn’t get driven much.

I know a guy w\ an Explorer(exploder) who never changed his oil, nor even checked it for that matter. So the thing smoked itself on a thruway trip & seized up due to lack of any oil. I gave my buddy a hand putting a junkyard engine into it. Iirc, i think it was all done for under $3k (~$2200engine + $650labor + fluids), which is not too bad compared to buying a new one @ $500 --$1000/per month! 😮😢👍🏻🛠️🔧🔩🤔🤷🏻♂️🚗🚐🚦⛽🛢️🚧
Um why did you not change out the other two caps when you were already in there. It was obvious the other two were leaking as well. You had it out and open. It was not like its a hard fix. I guess I just dont understand why you did not do it.
@@spagsketti you got me there, I must have been in a hurry that day. I replaced the other two a few weeks later.
Gonna blow a head gasket with you temp that high. I have a 1990 and a 1991 and they run NOWHERE near the middle. And yours is showing .75😮.. hopefully you just have a bad sensor. On my trucks at full temperature I'm 1/4
Never even noticed it. It doesn’t normally run that high. Thanks for pointing that out, I’ll give it a look over before I drive it next. This one doesn’t get driven much.
Gotta change your ECU fluid periodically 😅
Not to be mean... but, your soldering skills need work Thanks for the repair tip.
Could you recommend another channel or video that shows better technique for the viewers?
I wished I had a smaller tip handy and my variable temp iron didn’t want to work this particular day. That said, I’m a novice at best when it comes to soldering.
Brick nose not OBS
They need to start teaching a class on Ford pickup nickname identification in grade school.
With all due respect brother …. FUKKKKKKKK THAT!!!!😆😆😆😆😆
ABSOLUTELY NO WAY I’d waste my time doing that lol even simple as it is , I’d toss a carb on it before that lmao h should fix computers tho 🫡😜
@@elitecystuning it made the transmission shift better. A carb wouldn’t fix that 😂. It was super cheap and easy to see if it helped.
Seriously though, this truck has a lot of small issues and I’m not even sure which way to go with it. Full rebuild? Engine swap? Sell it off? Drive it with 14 small issues? 😂
@ lol I’m just bustin ass brother I have a 95 xlt one of my fleet rigs. Short bed 4x4 351 automatic .
Thing runs most diesels in drags 😆
I had same issues man these trucks aren’t difficult in hindsight and your bright when comes to what needs to be done I see.
IMO die with it lol never sell short bed f150s are most iconic American truck ever built🤝🫡
