I've followed all the vacum lines, everything is right.
Wired to have the fan run constantly.
what should i check next the ivac?

 

no codes either...reset the ecu too

 

Have you tried to just adjust the idle? Sorry to state the obvious

 

you never touch the idle screw...if you do you get screwed i've learned that in the past.

 

Follow the directions in a repair manual and u'll be fine bud.

 

yet no codes, vacum lines are secure and correct....going to try the ivac tonight

 

might seem too obvious, but have you checked the throttle cable/throttle assembly? if something is seized or not letting the slack off completely, that would explain it not going below 2500rpm..

doesn't hurt to check the basics before taking the whole damn thing apart

 

Good point Dude, btw, u keep mentioning vacuum lines. What would idle have to do with vacuum lines, just a question, and i seriosuyl want to kno the answer :0.

yeah i don't think whatever screwed you over in the past was an idle screw

 

Check to make sure there's no air in your cooling system. 2500 sounds too high for this condition, but if you have air bubbles in your cooling system, the temp. sensor will detect cold if there's no hot water touching it. It will then keep your idle elevated. Other than that you might have an air leak someplace or a stuck throttle plate.

 

why d ont u just adjust the idel

 

k, folks...this is why you don't adjust that idle screw...i know you'd probably love to do that, but you know what if the car was tuned for that and its reving that high...then there is no need. Your not fixing the problem, your causing another.

 

^no, sometimes that screw gets loose or out of place in time for whatever reason. theirs no harm or foul in adjusting it to the right spec that it came out of the factory, thats your own mis conception.
