ok so here is what i did and what is going on

i have a 2004 rx8 with 102000 miles the engine got replaced at least 20000 miles ago (thats what the previous owner said)

i bought it with the p2004 CEL Runner control stuck open or something like that

anyway i removed the entire intake maniflod, i got to the metal piece where the little apv motor goes, i removed it and replaced it.

while putting everything back together I had a hard time putting back the injectors but they dont shoot gas so i believe they are fine.

to make a large story short it starts, idles fine for the first 2 minute while it warms up
then it losses RPM's and drops to 500 or less

then by itself goes back up to 1500 and drops again

i give it gas and does good but when i let go of the pedal it drops the RPMS all the way and dies

by the way i changed the MAF sensor and the ssv solenoid

when did you do the work to your car?

Changing the MAF has a large impact on your car. Unplug battery for 20 min, pump brake pedal, connect battery, drive for a week- things should be back to normal. Your car is probably just relearning the fuel trims.

It could be other issues, but this is very common after MAF sensor work

I did it a week ago but the MAF sensor and the ssv solenoid were changed yesterday 05/17/12 and you might be right i didnt unplug my battery

I think you can just pull the "Room" fuse instead for 60+ seconds. That's what I do anyways whenever I've needed to clear the CEL light.
