so far ive checked coolant.. i let it run without the cap on to release as much airpockets

the IACV has recently been changed from the dealer

i reseted the ecu

swaped map sensor still the same .. any more clues?

 

huh? What exactly is wrong? What car/motor? Thats to vague for anything.

 

limp mode

 

its a 91 LS .. its not in limp mode cuz i resetted the ecu already.. even th it didnt have a check engine light on


i heard the a bad fitv could have the sam esymtoms.. but as high as 3k rpm? idle
?

 

What exactly is happening at 3k? You haven't really been too descriptive.

 

i think he means the revlimit hits at 3k...right?

 

i thikn i explained

3k rpm idle LOL

 

ohhhh, lol

 

Im thinking a 3k idle?

If so look at your throttle cable and make sure its not stuck, also look at the throttle body and make sure nothing is in it.

 

yes i checked the cable.. i removed the IACV and looked if the screen is dirty .. its clean..

 

HUGE Vac. leak somewhere??!?! (but that would prob. bounce up and down dramaticly if that was the case)

 

ya a vacuum leak woudl bounce... but this is steady starting at 3k rpm and rises little by little.. so i dont even want to warm it up fully not knowing how high it will idle lOL
