missfire on 2001 4.6 w/ supercharger
I have recently developed a missfire on my gt. Problem occured while getting on the car @ a high speed/rpm. I switched coil, plug, and injector still have the problem, missfire and very gas soaked plug. I think I have exhausted about all variables outside of the motor, what is the possible extent of the internal damage I may have caused? Also the car did not come factory with s/c, is there a possibility the motor can't handel extra boost? What test should I run know? Any idea if I can convert from sohc to dohc, (cobra heads)?
