For all those with idle problems

[C91BLX7]

My car just runs rough, not sure what it is but I have a bunch of fuel system cleaner/injector cleaner in the tank.

Is the car suppose to die if you unplug the IAC?

It should stay running...barely. But if the engine isn't running right to start, it'll probly die when the IACV is unplugged.


Great job guys, now we just need to pinpoint the delayed starting several people (myself included) have been posting about. I'm still stuck on that one and have giving up for now :P

ha, i just blocked off the FITV and bypassed the coolant line straight into the IACV and reset my idle

[cvc7chris]

i tightened the White Cap

it was loose

but still didn't fix my problem

i hear a hissing noise though

i can't find the leak

AWW

damn yo wen i first read this i was nah that mad expensive to change that and then this i can actually call god lol went and wrote somthing that should be in the archives till the end of time ive been having this problem for about a month and not even my mechanic new that all u had to do is take the top off and then screw it down ...... i had to tighten for like 5min but i got it and the bitch runs perfect thanx guy

To help out even further, if you having a surging problem there is a ring around the air bypass valve. turnit to the left to stop the surging.

won't turning it to the left make it even more loose?

i just replaced my fast idle valve yesterday and MOST of the idle problems are gone
sometimes the idle will go up and down a little....
what could it be...
do i need to adjust the thingy inside the fast idle valve?
or is it something else causing this problem?

fans kicking on...

[accordtunerf22]

i jus tightened the white cap and it didn't change a thing i've tryed everything in this world to fix this its stressing me out real bad lol

[b3nsonx]

replace it?

[jay82985]

i cleaned my IAC and when it warn out side it doesnt surge up and down but when real cold is when it does it ill try this tomorrow cause i been fixing this bitch up but the idle problem is pissing me off might go try to fix it now and yes i checked for vacuum leaks and a few other things also bleed the cooling system

[bcjammerx]

I had to re-adjust my idle screw three times! in just a few months...it kept backing out and causing the surging idle...it's stayed this time...

i dont get it? i dont think i have an idle problem? my car when i turn it on, it goes to about 1700-1800 on a good day to warm up i guess, and then when its getting up to normal temp ( to warm up the car ) it goes back down and it cna go down to about 1100 at that, and then once i start u kno putting it n R or D it'll stay around 800-900 RPM's max.. do i have an idle problem? also when im cold whne i first turn it on it rises by itself to 1700-1800 so yeah i think its just a warm up feature.. i likee!

[bcjammerx]

from the way you describe it you do not


the problem comes when your car idles at 2000 (not 1800) and stays there...
or when your idle bounces...pulses...goes back and forth...whatever...

900 up to 1800 back to 900 back to 1800 back to 900 etc etc...

normal is 1500-1800 till warm up then slowly goes down to 700-900...then after driving it ALWAYS goes back to 700-900 range at a stop/neutral.

Whoa, whoa, whoa.....that valve is expensive and before anyone goes out to buy a new valve try to tighten it first. Open up the top of the valve and put a screwdriver into one of the cuts on either side of the valve and turn it clockwise in order to see if its loose. It should be tight. I used two screwdrivers- one in each cut and turned them both at the same time.

I actually did that before I left for school this morning. Suprisingly mines was loose, I just tightend it down. I noticed a small bit of a difference today but not much...
