would the knock sensor throw a code of any kind if it is detecting knock when it is running?
i am almost certain it is the injector duration being cut from the ecu....since i can hook up a timing light and see where the ignition is when it is running. and it is not being cut or retarded. or the intake cam is out so the ign when it is going advanced it is sending spark out of time?? other than this retarded problem...
i cant hear any knock or ping. i am putting premium fuel in it tomorrow to see if that helps at all.
