rough running engine and lost power.
my friend has a 94 M6 Z28. he bought it about 1 month ago. the engine since he bought the car is running rough at all RPM's and there is big time of lost power. he did a tune up cleaned injectors, new spark plugs, new spark plug wires, new optispark, new O2 sensors, rockers were adjusted right 1/4 turn, and still that thing doesn't want to run right still running excatly the same way not even improved by even a hair. what would be that? coil? some defected injectos? by the way the PCM showed the follwing DTC's :
DTC22, DTC29.
any one can help?

DTC22 = TPS low voltage....make sure the TPS isn't sticking and that the wiring going to the TPS is in good condition (no broken insualtion).
DTC29 = AIR pump...just get rid of the thing...he's got a 94, so it shouldn't throw any codes at all.
Hope this helps!!
