i have been chasing down a small problem in my electrical system. symptom is when starting from a dead stop sometimes there is some hesitation and bucking(auto tranny) and sometimes when cruising there is an intermittant miss or something. check engine light does not flicker or come on. i hooked up the red snap on brick and no soft codes at all. so far i replaced and gapped the plugs,poured seafoam in the tank,changed the pcv valve. still not fixxed. bought a new front O2 sensor(brick showed it was a little lazy but working) and a coolant temp sensor. gonna install them tomorrow. also waiting on the new coils and ngk plug wires i ordered off ebay. if this doesn't work i am at a loss.
what else could it be?
