thanks, just put on new cap, rotor, plugs, and wires when i did the cam. The problem is now getting worse and intermittent. The car ran normal last night, but then this morning i had to limp it home. The symptoms were close to that of a boost leak this morning, no power/black smoke, but it happened whether the turbo was producing boost or not.

By the way i already replaced all vacuum lines,intake hoses (except one from airbox to turbo inlet), throttle body gasket, although not the intake manifold gasket.

The car is just approaching 100K miles and O2 sensor ect are all original. Should I start looking at sensors like these? To me it seems like the ECU is telling the car to dump too much fuel. what other sensors? AMM?

Again, any and all input will be greatly appreciated.

P.S. the good news is that i got my e-fan wired yesterday!
