Idle Sucks, help

[Xero]

okay, my idle sucks majorly right now, when it's cold, everthings cool, but when it warms up, the idle jumps around.

The idle is supposed to be at 700rpms +/- 50. What it's doing right now is dropping to 500, then coing back to 700, then up to 800, then back down to 600, then up, and down, and, you get the idea.

I have cleaned the IAA valve, and my throttle body. I haven't "cleaned" my intake track to the throttle body, but I did blow it out with compressed air, so I don't think that's the problem.

I think that one of the Solenoids on the IAA valve might be going, because when I had it out, I put 12v to it, and it didn't really want to work all the time, but I thought it was just me.

Would cap/rotor, and/or spark plugs screw up my idle? I doubt my intake did it, but could it have? what about cleaning my whole intake manifold, it's really nasty in there, THANKS!!

ya its probably your valve...i had the same problem and one day it just wouldnt idle anymore...i had to keep constant gas on it all the way home...not fun. I would fix it soon

The universal answer: Try a new fuel filter.

you know I had that same exact issue and of course I tried plugs/cap/rotor/fuel filter/plug wires and helped a little but then I had a friend check my timing with a timing gun and I was at 15 degrees which I was running lean so I adjusted back to 20 degrees and no more idle problems. Try checking that before you try everything else.

HEY! also try the connection in the plugs, you might just have a wiring issue if the valve is not trying to work all the time (the same thing happened to me with my TPS)
