94 - 95 Mustang Rough Idle
Вставка
- Опубліковано 11 вер 2024
- In this video, I resolve the rough and surging idle on my 95 Mustang GT. These instructions and parts listed below, will work on 94 -95 Mustang GT. I replace the Idle Air Control Value, throttle position sensor and PCV valve. I have seen these issues on most of my old Ford cars and find replacing all three parts, resolve any idle issues.

Thanks man for showing that, best greetings to you from Warsaw, Poland ;)
So just change stuff good or bad. I will just swap the whole engine to be sure.
The OP didn't explain how to set the voltage on the TPS sensor with a volt meter. Most times you'll have to modify the bolt holes in the TPS to achieve KOEO voltage between 0.79V and 0.98V
Good luck getting those screws out of the TPS next time with the thread sealer. I had to drill the heads off of the stock bolts first time I removed. And those parts store IAC’s are junk. Always go motorcraft for those.
I have never had a problem removing them on Mustangs but I had the issue you described when removing the original TPS bolts on Ford Ranger.
@@chasingmustangs why Ford decided to use Phillips head screws there I will never understand.
Who knows, and it is different from year to year.
@@chasingmustangs so, your haunting idle completely disappeared after you installed that new dizzy?
His TPS voltage was never set. That is why his car would not find idle.
Mine ended up being a crack in the pipe from exhaust manifold to the smog intake
can you post a picture please??
My 95 cobra has the same issues I hope this fixes it
Can you do a video on replacing all of the vacuum lines
I uploaded a video last week showing all the vacuum lines
Is there a specific way to put the TPS back on? I took off my TPS and am now getting a 52 code. Going to replace the IAC as I’ve already cleaned it in the past, wondering if I should just replace the TPS as well. & The PCV is so hard to find!!
Thanks for the video! Nice to see engines that match mine 😝
Yes, you have to make sure there is pressure on the plastic tab, but not actually moving the throttle. If you put it on wrong, if will increase idle and throw a code.

Lock tite on those wasn’t necessary
Agreed
Hey I’ve got a pretty well built 5.0 in a 95 gt, the motor always runs great, no misses,skips,pops, anything. But the car feels like it has half the power (no joke) for the first 30 minutes of it running. Then it starts to randomly feel like it’s running at full power and it will go back to running at half. Constantly going back and forth. Any thoughts?
Have you done the basics like replace the fuel filter? Is the engine making a pinging sounds?
DISCONECT A\C POWER AT CANISTER SEE WHAT HAPPENS.
Hello,
I recently acquired this engine for a swap project. However I intend to run it on an aftermarket engine management system. I'm having trouble locating the crankshaft position sensor. Has this engine got one or it uses a similar technology with the distributor system that it has? Many thanks!
It sounds like you got an engine management system from a 96 to 98 (or later) Mustang and you are trying to use it on a 94-95 Mustang. 94-95 Mustangs have a distributor and the sensor is in the distributor. The 96 - 98 Mustangs use coil packs and the crankshaft sensor is located on the timing cover next to the crankshaft. I believe it is on the passenger side.
My 98 4.6L GT doesnt have an idle problem exactly but it is actually very difficult to drive when i havent let the car idle for at least 15-20 minutes. The rpm's absolutely DUMP back to idle as soon as i put the clutch in, it will occasionally stall on the way out of my parking lot, if it doesnt solve itself by the time i get to the road i have to blip the throttle in between shifts so that the rpms will match to the next gear and so that it doesnt stall on the road. Its extremely frustrating but when it gets up to temp, its perfectly fine to drive.
I do understand that i should let any car warm up before setting off but it takes what feels like 45 minutes of idling for the coolant temperature gauge to show anything but cold start cold. I have no idea why its doing that. There is also a coolant light on, but i check all fluids daily and nothing seems to be changing, leaking, moving. Anything
Is the temperature gauge working in your car? The computer reads coolant temperature and it sounds like your car is not running correctly until the coolant heats up. I would look into fixing your coolant low issue and possibly replace the coolant temp sensor. You can always buy the part at Autozone and return it, if it does not resolve you issue.
@@chasingmustangsAuto Autozone won't let you return sensors after being installed.
I have a 1994 mustang everything is put back together expect it’s open headers right now. The problem I have is when I rev it it blogs out at 4k rmps. It did it with my other engine as well. Any thoughts or ideas?
So at 4k RPMs it starts stuter? does it do it when you drive or only when you rev the engine?
Can you please help me with my mustang? I’ve watched your videos countless times and can’t figure out what’s going on. I replaced IAC TPS cap and rotor, plugs MAF sensor and cleaned throttle body. Car would run decent then started running bad and now it’s only starting after minutes of cranking. I get a rough idle with backfire and misfire and I also replaced the ICM
Have you checked the timing yet?
@@chasingmustangs no I haven’t how do I
@@johnjohnstonee I would check timing before doing anything else. ua-cam.com/video/iqVzHmpSdsk/v-deo.html
@@chasingmustangs I can’t even get the car to start now… so I’m unable to check the timing 😔
@johnjohnstonee so the car cranks but does not Starr? The ignition module and ignition coil are the next things to check.
Hi this just happen to me today what was the three items you replace ? You also did the pvc as well ?
Yes, I recommend replacing the PVC if you have rough idle. Make sure to use a Motorcraft part, as I have soon problems with off brand ones.
@@chasingmustangs so buy both sensors from motorcraft and the pcv motor craft as well ?
@@William2005Ball Before you replace any sensors, checkout my other videos. I would pull the spout connector and see how the car runs. If you rough idle issues go away you might have a bad distributor. I would also double check you don't have any broken vacuum lines.
When replacing the sensors should I disconnect the battery??
@@williamvalentin2574 I always recommend disconnecting the battery.
Part number on the pcv part you used???

Where is the throttle position sensor
Its between the throttle body and the IAC. You have to remove the IAC to get access to the throttle position sensor. www.allfordmustangs.com/threads/1995-gt-302-5-0-with-rough-idle-and-weird-behavior-with-video.1079859/
@@chasingmustangs i think my problem is the distributor as well i just saw your follow up video im going to un plug that spout like u did and see if that helps hopefully
@@emagik12 Pull the spout connector before you buy the distributor. If you problems go away when you pull the spout connector, your distributor is the issue.
Next time close your door so we can hear it idle.
Good idea, will keep that in mind.
Will the Maf cause this issue? Mine idles the same way
Maf issues can cause idle issues, but they usually will not go away when the car warms up. Plus the car will usually throw an air code.
@@chasingmustangs Mine will have no check engine then 20 min after running throw a code
@@chasingmustangs also is there anything special to replacing the throttle position sensor or is it take old one out and bolt new one in, used to throttle position sensors were finiky and easy to mess up.
@@_R_E_D__ The throttle position sensor will only go on one way. Just make sure it is not forcing the throttle open. If that happens, you are putting it on wrong.
@@_R_E_D__ TPS is really easy to replace. As long you are not forcing the throttle open during the install, you have put it on correctly.
SO WONDER WHAT WAS CAUSING IT GUESS WE WILL NEVER KNOW.
It was the IAC and Distributor that was bad.
I would like to add the fact you never set the TPS voltage
