LTFT discovery For months now, I have been having positive LTFTs at WOT. This past weekend, I put back on my stock air lid and paper filter. I drove the car for a few days and today I rechecked my WOT LTFTs. They finally went 0! The
aftermarket air induction was making the PCM think the car was running lean.
Next I am going to try the aftermarket air lid with the stock paper filter and
see what happens.

I take it you were using an oiled filter before?
Did you do any cleaning of the MAF around
all this, or just "air laundry"? Sounds like it got
better, anyway.
