help with diagnostics....
what do you o2 sensor voltages look like? are they switching above and below the switch point on idle and low load? open loop is where your pcm is not using 02 feedback. I would test your o2 sensor and make sure they are working correctly. Remember if your pcm gets garbage in = garbage out.

well with it being the third set of 02s and all are brand new doing the same problem I kinda ruled that one out already.. but with the 02 not even plugged in it runs amazing?
Yeah because unplugging them makes the computer go back to open loop. If you have changed the o2 sensors have your checked the wiring for burnt wires or maybe resistance in the circuits? im sorry i did not read the entire thread but do you have any codes?
yeah went through and checked it all last night, nothing, and it never gave a 02 code... the only code that came up was the P0101 MAF which I just replaced it with a new one... still no codes without the 02 ?
That is strange if you leave them unplugged and drive the car you get no codes?
