jaydeem · 10-06-2011, 09:27 PM

i have a problem with my car!!!!!!!!! =( im tired !!!!!!! Anyways, my car will turn off if no gas is being pumped to it...I had problems with the car idling really bad before so........ I adjusted the spring inside the fast idle valve and tighten back together.... Now the car doesnt idle it turns off it i dont give it gas.!!!!!! Could this be caused by overthighting the part inside the fast idle valve.?????

I didnt have any problems before like this on the car. It would idle bad really bad i mean i was embarred on red lights... But now itll shut off.. wtf.??? I dont have any codes on the car either...

And honestly i just want to fix this and sell the car.!!!!! =(

anyone welcome to text me 520 461 7655.......

clean out the tb & iac with throttle body cleaner, maybe need to replace iac since taking it apart i never heard anyone adjusting them or rebuilding them before.

^ what he said.

Clean your Idle Air Control Valve IACV. Clean the screen and inside of it with carb or TB cleaner.

Clean your throttle body. Inspect cable and possibly adjust idle speed screw.

What you did to the FITV is fine, you are supposed to screw that piece in all the way. Did you clean that valve btw? If not, clean it.

when was your last tune up? wires? plugs? PCV? distributor cap and rotor?

there are many more reasons why you can be having this. You need to keep trying everything. When was the last time coolant was flushed and replaced? Air in cooling system screws up your idle also.

Search Google for cleaning techniques on the stuff I mentioned.

i never mentioned adjusting the aicv i said fast idle valve underneathe throttle body.... Yes u can adjust it theres a spring theres a write up to it as well......Sparks are new.... cables are good same as distributor how ever distributor cap has small tiny cracks where the screw goes too but idk if that would be it...i CLEANED THE THROTTLE BODY WITH TB CLEANER I CLANED THE IACV AS WELL I DONT REMEMBER CLEANING THE FAST IDLE VALVE DAMMIT I JUST ADJUSTED IT....not sure if that is it hopefully cus fawk is messing up..... I might cancell it... is that a good option... thanks for ur guys quick input

if if get the fast idle valve to tight.?? can this cause the car to shut off.???? thats my main ? because if so imma tackle that problem right now

JDMpreludeKing · 10-06-2011, 10:17 PM

i believe so adjust it loose because if it too tight then its getting no air in the valve to fast idle thats probably y its stalling

sry i miss read your first post i thought you were talking bout the iac

JDMpreludeKing · 10-06-2011, 10:29 PM

plus slude dan is right

do you have ac on?

its post to kick rpms up when ac turn on but may not be telling ecu to rev higher & dyeing (ive had this problem before)

but like what dan said it could be many other things or two problems going on at once

jaydeem · 10-07-2011, 06:27 PM

im taking the car apart right now......... im going to loosen up the fast idle valve...that was the only thing i did besides removing the fenders..... and it freaking killing me.... i cant drive this at red lights i need to start braking far away so once i get to the light i dnt stop so hard and the car shuts off....its so fawwwking annoying.!!!!!!!!! there is one hose that is loose it has always been like that though... i will post up a pic so u guys can help me

jaydeem · 10-07-2011, 09:27 PM

so i took if the fast idle and loosen it up a bit. Put it back together fired up the car and it turned of the same way..I thought it would stall a bit but nope!!! It took the same time to turn off

.......PUMPING GAS IS A MUST or it dies right away....Does anyone know how tight ur fast idle valve should be.?????
just to make sure..if you unscrew the inside of the fast idle valve the spring is really tight correct.?? i mean literaly if your not careful unscrewing it itll fly out far.....correct.??? or is it not suppose to be that tight??????? IF ANYONE TAKING IT OFF, UPLOAD A PIC OF HOW TIGHT THE SPRING LOOKS ON THE VALVE,,, AND THE WHITE PLASTIC (WITH METAL ROUND TIP)HOW FAR IT STICKS OUT...?????

picture here for hose mentioned.........its the box right on top of the battery.. its a black small box it has 2 hoses that go to it..... the second one away from left to right..... you can barely see where it attaches. the fist hose is ore visible......... can anyone tell me where it goes too.???

WHAT DO I CHECK NEXT.???

oH BY THE WAY I UNPLUGGED THE IACV TO SEE IF IT WOULD MAKE ANY DIFFERENCE,,,,,,,,,NOthing.!!!!!! as well it died right away.. the car didnt stalled at all...same iacv or not it dies right away....

P.S DO I ADJUST THE IDLE SCREW? I ASK BECAUSE SOMETIME WHEN I STEP ON THE GAS PEDAL IT KINDA GETS STUCK, AFTER STEPPING A LITTLE HARDER YOU HEAR A CLICK AND THEN YOUR ABLE TO PRESS DOWN.???SOMETIME WHILE DIVING ON THE FREEWAY ON 5TH GEAR FOR WHILE AND I TAKE OFF THE FOOT OF THE PEDAL AND PUSH IT BACK IT CLICKS AGAIN.....YOUR ABLE TO HEAR IT ON THE MUFFLER TOO.......... SO IS THIS JUST THE IDLE SCREW.?????

THANKD GUYS

Im starting to think that aint the problem.... ummmmmmmmm Im gonna throw a bomb at the lude..!!!! =D
