FYI, the other sensor that was slightly unclipped is the MAP sensor. I only know this because I swapped it out yesterday on my van which only slightly fixed my issue... which made me think it was the TPS... which brought me to this video. Thanks for the clear video.
@@complyvoluntarily I'm a bit embarrassed to admit that it was the fuel filter. I thought I had already changed the filter but I had changed it on a different van a couple months before. Decided to at least check it because it's so easily accessible, and sure enough it was clogged up with a brown gassy rusty sludge. Probably had never been changed in the 1989 van. Running great now. I'm still glad I changed everything else, though.
I’m looking at replacing this sensor but I got a different type of sensor (round connector with 3 pins) when I ordered my idle control valve . I can’t seem to find this specific one with that prong type connector .
If you think your truck is idling too high try adjusting the throttle position sensor those older style sensors are adjustable if you notice it has a small lever that moves back and forth if you loosen up the two screws you can move the sensor to adjust it at the idle you're most comfortable with
@@firearmconvention946 this is late but if it idles really high due to a lean mixture the computer will try to compensate by adding a ton of fuel to keep it running, but only up to a certain point. After that point it’ll die if you don’t screw with the idle adjustment or give it some gas. This’ll lower gas mileage and might cause computer issues over time. It’ll also run like crap, but it will run. Once had a friend disconnect one of my fuel injectors and the truck kept on trying its best to keep running, but would die at a stop if I let it idle without giving it some throttle. Little things like dirty air filters can also choke the engine and cause it to run rich and rough. If the computer or some other component like the ICM fries it’ll die on the road and even if you can jump start it or turn the engine over again it won’t run, so don’t be afraid to ask a more seasoned mechanic for advice or assistance if you’re not sure what you’re doing.
My 1992 Chevrolet Silverado extended cab 5.7 fuel injected engine was idling perfect but when i got on the road and gave it gas it was horrible wouldn't run but idle great so i changed the map sensor and o2 sensor and engine temperature sensor and finally the throttle position sensor and my truck ran perfect so it was the tps sensor so dont give up keep googling and good luck
Turned out the plug wires were corroded which was baffling because they weren't that old so I refused to change them out lol ! Lesson learn use die grease ! Cheers !
Before you put this in, was the truck idle going up and and down and were the headlights dimming up and down to the same pattern? Also was it stalling sometimes when you put it into reverse? Any help would be appreciated, thanks!
Evan Burns the idle was a bit up and down a bit and it did stall once or twice but Im pretty sure that it was mostly ignition problem. New Distributor and wires . Fixed it .
Recently got new distributor and plugs and wires but when at idle its rough and sometimes when i go in reverse it will die but also heard it might be the tbi throttle body any ideas ??
I have a 1990 Full Size Blazer 4x4. I don’t drive it much and for years it’s been idling High. There is no Tach in the truck so I don’t know the RPM but it is high and never lowers itself until I put it in drive. It runs great otherwise but I am stumped. I haven’t checked for any codes yet and there isn’t any light on the dash telling me to service engine. A week or so ago I checked You Tube out and mentioned about my High Idle. I came to a video saying that I needed to replace the Idle Control Valve. I did that and it made no difference whatsoever. It still idles high. Then I read that I should disconnect the battery for awhile then reconnect it for the computer to reset. I did that over night. Reconnected it and ran and drove it for about 45 minutes and it is still the same which brought me here to see if maybe it could be the TPS. Any ideas? My Blazer believe it or not has only 65k original miles on it. I have owned it since 1995. As I said I don’t drive it very much.
You are right on the money. Found out earlier today sprayed some Carb Spray around the base by the gasket. Left front was wiped. I know I shouldn't be spraying carb spray around a throttle body but I figured by the base of it wouldn't hurt any.
@@6bettyboo9 the one I got like that says that you have to hook up a multi meter to it and go through several steps to set the sensor, from idle all the way to full throttle..... Not just plug n play.... That's why I wanted to see you put that one back on..... Thanks for your reply
to be honest it ended up being a lot of different parts that need to be replaced but the main problem were the spark plug wires . I had replaced them a couple years ago and was convinced they were fine . They were corroded on the plug end real bad as was the cap . After I replaced the wires the problem stopped. go figure .
JMMJ Productions I wanna buy a 94 Chevy single can 4x4 the engine was replaced with another 350 and the dude says it runs fine but the tps is going out and I want it bad do you think it’ll be just a simp replacement
Cohesion tps is very easy to replace so I would wonder why he didn’t just change it out . My guess would be a lot if parts will need to be replaced but thankfully they are all very cheap parts . As long as it running and drives the rest can be fine tuned .
JMMJ Productions he said it runs amazing but he hasn’t drove it enough to be a problem I guess he said it’s slowly going I wanna buy the truck and change it out
You didnt show us how to chand the sensor so y make the vidio thiers a o ring gasket the goes in the sensor that dosent come with it and you cannot get at a zone or on line

better than most videos, you actually drove the vehicle. most people don't even test their work.
I changed the distrubutor,cap, rotor, spark plugs, wires, egr, and map. Once i changed the map my truck started running correctly

Is there a problem with it idling too high??
Maybe distributor timing is off a little
I have a 94 Chevy Silverado 350. Is that one adjustable too?

@@mealswithdadjust get a MOPAR and stop the GM junk
👍
Did you use a AC Delco part? And was the one you took out AC Delco as well?
Before you put this in, was the truck idle going up and and down and were the headlights dimming up and down to the same pattern? Also was it stalling sometimes when you put it into reverse? Any help would be appreciated, thanks!

I have same problem what fixed it ?? If u got it fix thanks

I gave my truck WOT and it stumbled at like 1800-2000 rpms. Plus idle kinda moves around. But it picks up. I’m thinking it might be this
Very helpful
Interesting. An install video without the install. Hmm.. Keep the audience guessing the plot. 🤷🏽
I am aware im lame thank you. Really its just the thre little bolts and that it.
Was it blowing black smoke like it was getting way to much fuel and

Could be a vacuum leak . Spray brake cleaner around the intake manifold and listen for any changes . Intake leaks are common.

@@ffas23 right on !! I love that ah ha moment lol !
That green plug is ur map
I belive this is an 87 suburban- old body style
Title says 88 but I always end up with87 parts lol
what did you use to take out the bolts?
Does it still have the smog pump on the engine. See the smog vacuum line still there.
Yes still has the smog pump.
Why did you NOT adjust it????
Didn't know you had too. Still working great.
It's not adjustable on the V-8's.
When you say that it was the distributor, do you mean the cap and rotor or the entire deal?
I replaced the entire distributor the parts inside were crispy . 220k I'm sure it was time.
@@6bettyboo9 i have 168310 on my 1988. will try to just swap out the cap and rotor
what brand did u install and was it new or reman?
@@donwiley8110 do the wires and plugs too.
ac delco only.
@@complyvoluntarily I did those too. Thx
That's a map sensor
You could have at least shown us taking it off and how to reinstall it back
It's really easy and didn't think it was necessary. Thank for watching!
Why didn't you show yourself taking it off. And putting the new one on?
Mostly because I dont have a tripod or the like. Sorry . Just take the bolts off unclip the wires and boom you're done.

Did that fix it
Michael Louis turned out to be the distributor and the plug wires.
Did it fix it?

I had replaced them a couple years ago and was convinced they were fine . They were corroded on the plug end real bad as was the cap . After I replaced the wires the problem stopped. go figure .
however the EGR was bad . and so was the distributor . I also replaced the o2 sensor and it was real dirty as well. Runs like a top now . no codes .
