For about the past year i have had an ellusive misfire, it will creep up every few months for a few days then go away. Normally with the A/C on, i guess the additional load on the motor was hurting it. While cruising it will start to jerk forward and back. It is not tranny shudder, i have had fluid out of the tranny 3 times in 30,000 miles, 2 pan drops and one drained converter. all three times the fluid was in near great shape. The car has a slight stumble at idle.
After i giot the car at about 90,000 miles i replaced the original wires with some cheap wires and replaced the plugs, after the misfire re-appeared i put the original wires back on, that helped out a bit. a few thousand miles ago i replaced the plugs again, about 20,000 miles on the plugs but due to the waste spark ignition f had the equivelent of 40,000 on copper plugs. this helped for a while, yesterday i drove to Bradenton (about 80 miles round trip all interstate) car ran fine.
After i get back in town turn the car off for about an hour driving along t about 40-55 car starts bucking again, does not matter if it is in 3rd, 4th, barely off idle or with the pedel down, still bucking.
For the hell of it i tested the cheapo wires, 6 of the wires had about 7.5-9.5 kOhms of resistance, 1 had around 11 and the eighth one had about 20kOhm. So im thinking that the original wires have far surpassed their usefull life and the cheapo wires went to shit reletivly fast. so Now im going to buy a set of Taylor wires.
