[QUOTE="Ellison3, post: 1889509, member: 57565"] That dirty sensor should get sprayed with CRC MAF sensor cleaner, or something comparable. Also, clean out the throttle body. Remember what I said about the throttle body butterfly… only manipulate it with the harness disconnected. When it’s connected it’s default position is commanded to close. Moving it with harness connected can cause damage. You also want to get that blow-by… that way it doesn’t keep contaminating your intake, and associated components. Did you look at the plugs? Actually, thinking of changing my plugs as I’m noticing a slight fluctuation on the RPM gauge. Looks reminiscent of what the tuner pointed out to me before the last dyno run. He swapped them out before tuning. [/QUOTE]
