its 02 gm 5.3 lm7 engine with 4l60e. has btr s4 cam. shorty headers and full exhaust. everything else is stock. the engine starts and idles pretty good. only problem I have is the maf keeps going bad. and the fuel trims are to shit. has new o2s and they work good. but when I plug them in the engine run rich and fouls the plugs. with them unplugged it run and idles better but still alitttle rich not enough to foul the plugs tho. but it miss fires as I drive it, and it wont stall at all it just has no power and wont even spin the tires. anyone else have a idea what I need to do besides take it to a tuner. im trying tune my self atm. im gonna post my tune and a few logs and hope someone can help.
