Basically I'm trying to determine if you have a false air situation going on. A small leak will drop the MAF g/s since all the air isn't getting metered and the fuel trims will go up a little to account for the extra air.
With MAF plugged in it can run but feels unresponsive/sluggish.
Unfortunately the wife came to remind me we have a dinner appointment & I should leave my "little" project for the morning.
I will do a test run first thing in the morning & i'll post results for you.
You think an air leak would cause this TB problems?
Thanks for the input/help thus far everyone!!
