Power problems sometimes Hi I have a 04 gto it has a cam,3000 stall,long tube headers and intake manifold. Before intake and headers when the AC was on it had no power I could put it to the floor and nothing it would shift before 3000rpms no mater what. After headers and intake it has gotten worse even with AC off alot of the time it has no power. If I put in first and manually shift though the gears it has all the power. Any help is greatly appreciated

Any check engine lights? Check the knock sensors and front 02 sensor.
You can check for stored trouble codes by:
1-Put key in ignition
2-Hold MODE and SET buttons down at the same time
3-Turn key on without starting engine
4-Hidden menu appears, cycle thru with up/down buttons to the fault codes page and take a picture or write the codes down and check them.
After you have the codes disconnect the negative battery cable for about 5-10 mins and it will clear them from the computer. Go drive around for about 30 mins and check for codes again.
