If you remove the MAF, make sure you not which way the black plastic piece that stays inside is facing so you can get it back together right. If you turn it one way the air can flow, if you turn it the other it will block the flow...

i would still just recomend blasting it with some brake cleaner i do that to mine every oil change...

Dont listen to my post as it turns out the black plastic peice is supposed to be attached in there..mine was broken and I think thats why my car is running like crap..

Ok I pulled it out and cleaned to, mine has a double filament in it, so I cleaned them both. Started the car and it feels a little better. So far it'* still dropping in idle, but it hasn't stalled yet. Now I'm thinking Idle Control Valve. Should that be the next logical step?

Ok gentlemen I still need assistance. The idling is still FUBAR'D. Once again I've cleaned the Mass Air Control valve, replaced Idle Air control, good fuel pressure, oil and transmission fluid has been changed, new PCV valve. I'm lost, any more ideas?

Check resistance of all coils. Have you changed the plugs and wires? Clean throttle plate?
Add fuel injector cleaner additive with water remover.

tune up and fuel filter would be my next logical move since you replaced almost every other sensor
oh p.*. the PCV is on the firewall side towards the intake on the upper intake manifold for all who did not know the 92 SE and all L67s i believe are in this location in the upper intake or supercharger

If I read correctly, you put your hand up to the intake, blocked it, and it stalled? On a good running engine, that SHOULDN'T happen, unless you block it completely with a solid object, air tight. Which, to mention, you should never do. Thats way too much vacuum pressure in the intake...no idea what could happen, but don't go there.

Heres a list of things to do in this situation, I see you've done some, so disregard those.

Clean MAF (with designated MAF cleaner or alcohol ONLY)
Check ignition coil resistance
Check fuel pressure
Replace fuel filter
Check IAC
Replace PCV
Replace Spark Plugs
Replace Spark Wires
Seafoam into intake
Seafoam into fuel tank

and how many miles are on this engine?

Ok...lets see, this is what' i've done:

1. New plugs
2. New fuel filter
3. New PCV
4. New Idle Air control valve
5. New wires
6. New alternator
7. Oil change
8. Transmission flush
9. New transmission filter
10. cleaned the mass air control valve
11. Cleaned Ignition Control Module and it tested fine...went to Napa

I got a new O2 sensor that I'm going to put on there, if that doesn't help then I'm going to look at the cam sensor. Fuel pressure is great...getting plenty of fuel.

Anything I've missed?

Did the rough idle start before or after the new plugs? (sorry, I skimmed the topic) and is there a chance that one could have been cracked upon install? Also double check the wire connections, making sure they are not loose...and that they are connecting the correct plugs. Did you say if you get a Check Engine LIght or not? If you do, you should get it scanned - the code can help to narrow it down.

I had a similar problem...it ended up being two things. Cracked #6 plug and a bad MAF. Took us a long time to figure it out...don't give up!
