To find a VAC leak you can use throttle body cleaner and spray around fitting, couplers, etc.... if there is a VAC leak then the cars RPM will jump up for a second. Car could be rich in order to compensate for the "high air input" reading your getting from the MAFs. Which side is reading off, or is it both?
The RPM did jump up for a second from idle, which is weird since the car has been running great. I don't think the CEL differentiated between sides, it says MAF Bank 1/2 I think. Maybe I could run a datalog and see which side looks off?
