About 3 months ago I had the dealer clean the throttle body and it ran a LITTLE better (not much). But recently I've noticed a weird lag at 3/4 to full throttle - and the lag seems to be getting more prominent. Could it be that when they cleaned the TB they messed up the MAF? (No SES light yet). Is the MAF so sensitive that they could have jarred it upon re-installation or possibly got cleaner on it (as I've read in past posts)?

BTW, my car is a 2000 SE.

Thanks,

Bill
