I ended up replacing the maf with a new one (the junkyard one was bad). It would drive, but not idle. Replaced the iac, and all is good again. I think me jimmying a screwdriver in there fubar-ed it.

So, I replaced the MAF sensor, and the car runs much better. It is now able to accelerate and idle. After reprogramming the ECM (idle until warm, 1 minute in N, 1 minute in D, 20-50% throttle to top gear) and driving it for 20 miles, it seems to run much smoother. However, my idle still feels off ...

Thank you. I did try cleaning the IAC valve, and tested it by applying 12v to it. The motor operates, but does not open or close very much. I am not sure how much it is supposed to move.

So, this sounds pretty simple, like it should be the MAF, but I want to be sure before I invest in yet another part.

Story goes like this, driving along the freeway and suddenly feel a small loss of power. Not enough to be scary, but enough to notice. Try flooring it and it hesitates before it ...
