i know the feeling.... trust me. 3 transmissions and 2 motors have been swapped since i got this car. did u have colder plugs also? seems like u were somewhat ok to run a 3.4, only thing really lacking was plog of headers. front manifold= FAIL. have to ask cuz of some posts i see around here... u do run highest octane gas u can get right? if u part it out i may be interested in the PCM. how hard were u on the throttle when it took a sh*t?
