I have a 92 si hatch an as soon as i turn the car on its jumps up tp 3,000 RPM's
I Don't know what wrong. The engine isn't not trowing any codes,when i ask people what could it be they say it is the sensor behind my intake manifold. Are they wrong? what could it be?

Thats the sensor


Better shot

Is your throttle cable sticking?

Patron

are they saying it's the TPS sensor? I would think distributor, mainly the ignitor or coil pack.

JDMRob

Nah i dont believe so cause it will go up to 3,000 Rpm (sometimes lower) an will go back down an then go right back up again.
Its Weird

It may be your IAC (intake air conroller) not working right letting too much air past the throttle plate causing high idle. cant say for sure though.

no way man! never will the distributor cause idle to be at 3k rpm

IACV = Intake Air Control Valve. $125 new or $50 used.

JDMRob

where is the IAC (intake air conroller) located at under my hood so i can see if thats the problem

Mine did the same thing and it was the intake manifold gasket had a hole in it. Take some carb cleaner and spray around were the intake manifold meets the head and if it revs up then you will know....

Intake Air control valve. Not intake controller valve.

Take the IAC off and tighten the plastic screw back in. That sound fix it. Also check the TPS senors. Make sure the voltage is at .4 for idle.

PM me if needed. I'm a litte drunk

also just try cleaning the IACV. take it off and shoot some carb cleaner in there. I've even used simple green before, let it soak, rinsed it out really well and dryed it out with a hairdryer, worked like a charm and cost next to nothing

Where the hell is the thing u guys are calling the IAVC located?

It's your first picture.

What I was thinking.

JDMRob

any other suggestions on what it could be??

He;s got it. And if you spray around the intake mani with carb cleaner, the revs will drop, not rise. Pull of the IAC- it's the sensor behind the intake mani that you showed in your pic. There are 3 coolant lines and 2 12mm bolts. Pull it off. There's a plastic spring which regulates the air into the intake mani. There's also goin to be a metal screen. This is most likely clogged. Clean it up good before your ecu thinks it's bad. Carb cleaner, simple green, whatever JUst get it nice and clean, reset your ecu, and fire it up.

does it just idle there??.. try playing with the IAS

Evs-One

actually, before you pull off the iac...get the car to operating temp, and pull the plug off of it. If the idle goes down, then that's your problem. If not, then look elsewhere. This will be the easiest way to tell you if that's it.
