ok, so I have narrowed down my 98 GTP issues to either ecu or wiring. now my question and i do not know why i did not ask this before is....
should the gtp start with an ecu from a 05 impala ls with the 3.8 non sc and just run like crap, or do i need to try with an ecu from a 98-02....
i have a 05 impala as my daily and other than swapping coils and some other sensors to see if that was the problem have not attempted the ecu yet. not sure if its worth the 4 bolts to get it out and in the gtp to try.
