    today i changed back to original plug wires and switched coil pack 1 to 3....i cleared all codes drove to the store with scan tool hooked up...ran fine to store no codes... when i came out and started it, i noticed it was stumbling again, it tru only one code this time po302....i believe the wires i put in were bad or i mixed up cylinders..i think this because i have the original code i started with before changing wires....could it still be the coil pack as to it is showing a code for only one cylinder and the coil connects 2-5 cylinder? im at a lose at the moment and back at ground zero....any advice would be great...thanks

Usually a p0300 is a random missfire code due to a fuel problem probaly bad gas , use some in tank fuel treatment such as techron or lucas injector cleaner, after adding fuel disconnect negative terminal to batt, to clear codes and see what happens

PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

Cpi unit is not working right what should i do


purchase a "noid" fuel injector tester from an auto parts store; it is a small light attached to a fuel injector plug unplug an injector from the wiring harness and plug in the "noid" to the injector harness connector you just removed; start the engine: if the "noid" flashes when you crank the engine you will know that that fuel injector has power to it, then: use the "noid" to check each injector in turn. if the injectors are good test the fuel pressure with a fuel pressure gauge; low pressure suspect a bad fuel filter.

Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code
