NeonKnight Posted February 25, 2006 Report Posted February 25, 2006 Well my car has a lifter ticking, so i needed to do an oilchange, i did it and ran some engine stuff that my mechanic recommended to free up the lifter if its stuck. well when i was doing that i pulled out my IAC also. the thing was gunked like no other with carbon. cleaned it off cleaned the IAC plate thing slightly, put it back in and it ran like shit... was somewhat missing at idle, and was just horrible. tried to drive it around the block, and whenever i gave it enough gas it started to do the idle drop down thing like when i turn the car on, high rpms then drops lower. well it would just go higher rpms and stay there, it wouldnt miss or anything. so i tried to press the brakes... which might i add suck ass! and the car just does not stop lol. once it does the idle returns back to its bogging state. so i brought it back home, cleaned the IAC with carb cleaner. and it runs like it used to... except for the fact that it is having a Loss of power... it just does not feel powerful like it used to... it really feels like a piece of crap... or said by others here... a TURD!!!! and by the way the lifter is still ticking, i have to wait for that additive shit to settle in before it should stop. so im really pissed at my car... what could be making this thing have a loss of power..? any ideas? (besides that it needs a full tune up) just things that could make this happen recently Quote
slick Posted February 25, 2006 Report Posted February 25, 2006 Did you push the pintle back to the correct position? Quote
Euro Posted February 25, 2006 Report Posted February 25, 2006 does the lifter tick happen all the time? 3.1's do that for a few minutes on cold start-up Quote
5speedz34 Posted February 25, 2006 Report Posted February 25, 2006 Did you push the pintle back to the correct position? It should "set" itself after the relearn, or driving it for a while right? When was the last time the car got a tune-up? Quote
NeonKnight Posted February 25, 2006 Author Report Posted February 25, 2006 um 120k miles... that was about 3 - 4 years ago? hahaha, it now has 149k miles. the idle is fine now... i think.. it just feels like donkey shit and the lifter tick happens all the time.. sometimes i do not hear it on startup.

slick Posted February 25, 2006 Report Posted February 25, 2006 Did you push the pintle back to the correct position? It should "set" itself after the relearn, or driving it for a while right? Nope, you have to depress it to the correct position. Are you sure its your lifters and maybe not your injectors ticking? Quote
Brian P Posted February 25, 2006 Report Posted February 25, 2006 are you sure the vacuum lines are bck in place on the tb, and the gasket to that upper iac block is good?? Quote
NeonKnight Posted February 25, 2006 Author Report Posted February 25, 2006 yea those vacuum lines are good. the hoses are not leaking and are all air tight no leaks. i checked. how do i know what the correct position is...? Quote
NeonKnight Posted February 25, 2006 Author Report Posted February 25, 2006 well i had to drive my friend home, she said it still feels the same... but i guess to me it doesnt, maybe it didnt before but i dont know... it can be hard to tell... tomorrow i am going to idle relearn, and maybe even clean out the IAC more. is there a IAC gasket under the IAC thing...? im thinking of getting a new EGR soon also, and a new cat converter. since mine are both original on the car.

An EGR valve isn't really regular maintenance, If you're trying to just clean out carbon, I'd take off the plenum and remove all of the caked up carbon from the egr port and the adapter. Do you mean under the IAC itself or the plate on the throttle body? Quote
Crazy K Posted February 25, 2006 Report Posted February 25, 2006 IAC relearn.. IIRC turn the key on as if engine was on, do not start car, wait 30 seconds, the IAC will cycle... done... Quote
NeonKnight Posted February 25, 2006 Author Report Posted February 25, 2006 nice im going to go try that right now, and i mean the plate that the IAC goes into that has those torx screws Quote
Turbo231 Posted February 26, 2006 Report Posted February 26, 2006 does the lifter tick happen all the time? 3.1's do that for a few minutes on cold start-up Some 3.1's are BAD at ticking. My uncle's father in law has a 96 Century that sounds like someone whacking it with a hammer...well, a little TSB states the issue...the piston to the wrist pin...well, if the wrist pin hole is to the upper tolerance the wrist pin is to the lower tolerance...well, a lot of banging all 6 cylinders happens...of course, the only fix is replacement and it is not a warranty item for GM as technically, the car still runs. I'd bitch and complain, but he is a softy. Quote
Brian P Posted February 27, 2006 Report Posted February 27, 2006 is there a IAC gasket under the IAC thing...? There's a gasket on the vacuum distribution block/plate (what the IAC bolts onto) also there's supposed to be an O-ring on the IAC valve before installing. Be sure it didn't fall of, split, or seat improperly. Quote
NeonKnight Posted February 27, 2006 Author Report Posted February 27, 2006 no i fixed the IAC problem. i took the O-Ring off when i sprayed it with Carb cleaner... didnt want it to shrink or expand. but it still lacks its power lol... and that lifter tapping is annoying i put that stuff in the car that frees sticky lifters... 100 miles later nothing! i had to make a few trips to san jose haha... so yea im going to rip it open this friday and replace the lifters... or lifter...

1990lumina Posted February 27, 2006 Report Posted February 27, 2006 Stop beating on it (in the racing section) and then you won't have so many problems Quote
NeonKnight Posted February 27, 2006 Author Report Posted February 27, 2006 HAHA.... yea i know lol.. the poor car. Quote
