Engine stutters when putting it in gear

found this on another forum:

Sounds like a possible problem in the Cold Idle Control Circuit - such as the Idle Air Control Valve not opening enough to keep it running in those conditions like just being started and driven in the winter.

You should be able to confirm my theory if, next time, you push the gas pedal a little and hold it there as you put in gear, if it stays running then, that's probably what it is - the valve being too cold to open fast enough for the changing load on the engine etc...

so is there any other way cleaning the iacv other than spraying it with carb cleaner and wiping it out with q-tips?

so i replaced the idle air control valve and i still have the same bogging down when put in gear. it only does it when the engine is cold. after it warms up it goes into gear just fine. this is really bugging the crap out of me.

i may have figured it out. this morning i had a little extra time before work so i decided to pull the plugs and inspect them. turns out they were all gapped to .040. i opened them up to about .044 and it seems to help. actually i only pulled 6 out of 8 plugs. the rear 2 on the drivers side are near impossible to get to with the upper intake manifold on. seams like the pre 98 guys have it a little easier. ill keep this updated.
