actually read a couple of threads with people experiencing the same problem(s). turned out to be the intake cam timing being advanced

No. Not from what he describes. And as a percent of total populaiton - very few experience timing shifts.

Vacuum leak
EGR
IAC
Leak in the intake tubing
bad coils

does the iac have a triangular looking gasket similar to the egr? One that would go in between the solenoid and where it attaches to the valve body.

this is the style of gasket im talking about. (this is the egr gasket)

 

[shane02pro5]

Yes It is directly on top of the throttle body. I don't visibly see a gasket I think there's an o-ring in between. I have 3 tb's in my kitchen lol

? thats the rubber gasket that seats into the iac valve body, correct?

cool. i know theres the o-ring, just wasn't sure if i was missing the thin metal gasket. thanks
