Idle problem
 

Hey what's up all, I like your forum. Anyway I've done searches and tried everything under the freaking sun. I've changed my IACV, map sensor, throttle body "with new TPS sensor" adjusted the idle screw. Nothing seem to make my idle act right. It does what ever it wants all the time, sometimes it jumps from 700-1200. Sometimes it idles at 1500 some times it idles at 550. Any idea's? I'm getting ready to put my turbo on but I want to fix this first "I'm paranoid that somethings going to screw up my engine". I don't know what else to do, I'm getting so frustrated. Thanks for any help :-\

hrmm.. all that replace.. im assuming you have reset the ecu and set idle as per PROPER instructions via the manual?

possible a kinked/loose/clogged vac line is all i can think of otherwise.

Well actually I hadn't tried that, so I will, hopefully this works, thanks

i am haveing a similiar problome, though i havent tried much yet. i replaced my tps, took the throttle body off to do that, and when i put it back on, the car is idling funny. well when i first start it, it will rev at like 2500 and slowly go down, warming up, it did it beofre i changed the tps, just checking if thats normal. but now, since the tps swap, it will rev to about 1500 then drop to about 1000 then back to 1500 and so on. i am thinking vac line, but how do i check them?

did u use a new TB gasket? constant up and down idle is a vac leak/plug.

I have this same problem on my '94 integra ls. But it only does it in the cold(winter months). I've replace the fast idle valve and pcv valve and no luck.

Can anyone help us??
