i have a 98 gtp super charged I have done nothing but work on this car since I got one thing after another but I love doing it so I kinda look forward to it breaking down some times but this time I just cant seem to figure it out I changed the fuel pump car ran fine girl decided to do 180km down the 407 and ever since then the car misses the perf shift light will not come on the engine light is on the car misses throught out every gear especially lower rpms that are under load ( going up a hill and car kicks to last gear then the supercharger boost light shows that the supercharger is giving like four bars of boost then you hear a ting type sound the boost kicks off and the car will start to jurk like its stalling and firing back up if you give it like say three quaters pedal the boost will come on go full but the car has next to nothing for power and the engine light will start to flash. I have checked all sensors I have 5 volts to them on wire hrness I have put odb2 tester on and checked and replace what the codes were and now the only code that is left i forget the number but I know it is the miss fire cylinder 6 code I have spark there I thought maybe it was injector so I pulled fuel rail and replaced that too but nothing maf map all evap lines throttle position sensor all good the tester will not tell me any more just says miss cyc 6 I do not have a compression testor or a fuel pressure tester but i do know that there is fuel pressure but i do not know if it is right and the fuel pump i got from a buddy used and he told me it was for a gtp but it could be a gt or something not sure there either anyways just putting this out there in case anybody else has had simular issues and could offer some insight thanks I love my car and hate seeing her run like this please help my baby
