Okay so i have not owned the car very long but ever sense i have it has had a slight sputter in the higher rpms, then recently it started to feel like it had some resistance when i would give it gas and the car would slightly pull back then it would clear up and pull fine after a few seconds, then just 3 days ago it started bucking and misfiring a bunch I managed to get it home, i put new plugs in, didn't help, then new wires, and a diffrent coil with no effect. So i wiggled the injectors and tapped on the power transistor and the car started driving perfect. Better then it ever has and my wideband was better also. Before it sat at 16 and dipped down to maybe 12, now it will drop to high 9. So i drove down to the store turned the car off when i got back it was running like crap again. Only thing I can think of now is power transistor? I pulled the wires 1 at a time while the car was running 2 of the wires would make a 2" spark nice and blue to the valve cover, the other 2 (middle two) I have to hold almost a 1/4 inch off to see a yellowish spark.
