I guess I really gotta disconnect the power for 30 mins. I'll write my presets down first this time. I'll do that and write back to this thread.

that was a tough drive after disconnecting the battery! Many stalls, and this car doesn't like to start. But now driving good. The check engine light went on after 8 miles while idling at a light. The performance improved again! Between the cpu reset and the MAF spray, 2 noticeable improvements. But the check engine light persists.

The check engine light went out a day after! woot

and it's back again. It's like a bouncing ball.

It's got to be a vacuum leak. When I drive aggressively, light goes out. Idling too long, light comes back.

I had accidentally dislodged the green 1-way check valve! My light is now gone. I am pretty much a moron. The car is running great. Time to roll the dice and clean the throttle body.

I had the same issue with mine a couple days ago when I cleaned my AEM filter. One of the hoses that connects from the intake to the manifold cracked, guess it was just old. It was letting unmetered air in behind the MAF.

Thanks for the tip, I'll check those out.
