That happened to me once, my car ran horrible, and popped the hood and the exhaust was glowing red hot, turns out, the intake hose that goes from the air box to the TB had some how came off, there fore the MAF sensor wasnt working at all. Try to put on you old MAF sensor and see if that helps any.....

Antifreeze in the converter could have damaged it. Or it simply could be plugged which lead to your head gasket failure. Get that fixed before you run that motor much.

now it will hardly run unless you are holding the throttle and it is always popping out of the drivers exhaust very loudly. you have the bump the throttle to get it started. I tried the stock maf and still doing it. the head gasket was blown on the pass side. (I am only running the down tubes and cats, temp untill I can get to the exhaust shop.)

I think you are running rich on the drivers bank and fuel is burning inside the CAT. I would do a fuel pressure leak down test. You may have a bad injector that is dumping fuel.

I found the #5 and #6 injectors sticking open. I need to get bigger ones anyway.
