Diagnosis nightmare, KA won't drive...

[F-bodeee]

Ok, the car won't accelerate or drive. It will run when the MAF is unplugged, its in limp mode and runs really rich. When you give it gas when the MAF is plugged in it it shuts right off, kinda like its getting too much gas. I replaced the MAF, the TPS, the IAC valve works, the the coolant temp sensor works, knock sensor is fine, it still shuts off on accel. I have no idea what is wrong, i'm thinking its something with the wiring harness. ANY IDEAS?

Injector O-Ring are leaking? Or injector stuck open...

Those two would be my guess!

Do you have a Fuel pressure Gauge?

check your fuel rail return line if it is clogged of krimped when you step on the peddal all the fuel pressure builds up at the fuel rail and sprays way more then it should causing your engine to flood. also i would check the o2 cause if this has been happening for a while or slowly started to run richer and richer you cat might be bad and if the o2 is bad would cause the limp home mode also
