Car RPM Sticking

[CanaryGT]

So I was driving around and I noticed that sometimes my RPM's are just sticking at like 2000 RPMS. When I am in neutral etc. As soon as it goes into gear it goes back down. Any insight?

Sounds like this is an issue with your IAC valve. You can try cleaning it but either removing it completely or buying a new valve are the only options I've heard that work. Also check the gasket on it to see if it has just worn off.

 

[CanaryGT]

Yep Prolly so. Any one have One or know of a good place to buy?

Get a new IAC valve at any parts store and check your TPS voltage.

IACs are famouse for going bad in the 94/95 cars. try cleaning it out with electric parts cleaner and if that doesnt work buy a new one

 

[CanaryGT]

Yeah I cleaned it out and reset my battery. It worked Ok for about 5-8 mins. Then it started all over.

Im getting to a point where Im sick of all this shit breaking. I wanna sell it..

 

[det_riot]

try just buying a new iac valve and see if that helps

 

[CanaryGT]

Yeah I will. Its just 100 bucks that I dont want to spend atm. Rather buy SC2...

I think you need a new IAC. The small motor that drives the plunger inside may have stopped working, in which case cleaning it won't help.

See, god said so himself^

 

[CanaryGT]

Yeah... I guess Ill go buy one....

 

[CanaryGT]

Bought One. Gonna Put it in Tomorrow or Monday. Let you guys know if it fixes it.

 

[det_riot]

Excited to see the results! Should fix your problem. How much did you pay for it and from where?

 

[CanaryGT]

Paid 100 bucks and Nope Didnt fix my problem. So Im on to TPS and Vacuum leaks..

 

[det_riot]

damn, shitty luck. keep us updated with your findings! Did you put in the new gasket with the iac?

 

[CanaryGT]

Yes New Gasket. I checked my TPS and at Idle im at 1.45 Volts so yeah Its off. The problem is even with elongating my holes it doesnt seem to want to adjust below the 1 volt mark...

 

[CanaryGT]

Is there such an animal as an Adjustable TPS sensor for a 95 mustang?

 

[ryclef331]

drill bit and elongate the holes....or you current one might be crapping the bed on you. If the range can go from .97-.99 at idle to 4.97 to 5.0 wot.....then you need a new one

 

[Paul]

94-95 TPS aren't adjustable, and have metal sleeves in them which don't make "elongating the holes" very easy. Plus, I thought that the T4M0 adjusted for min/max TPS voltage at idle and WOT - or did I make that up? I'm old and forget easily.

Paul.

 

[CanaryGT]

I drilled out those sleeves and played around with it. I can only get it to 1.21 Volts. In that volt range the car idles fine now. SO I have no Idea.....
