I went with AC Delco wires, I prefer those, or the NGK'* myself.

you make sure the terminals and wires seem good? not doubting batteries can change with heat but normally the battery temp doesnt change temp as fast as the wires(big pos and grounds)

Hi everybody, sorry for such a delay! Installed new Bosch wires, cleaned up the icm, and air flow. First time out got lousy fuel mileage; second time out (by out I mean stint between refueling and driving), I got a fantastic 28mpg! Then the strangeness began! I filled the tank, drove about a mile home and parked the car. The next morning, because of bad weather, I drove my wife to work; as soon as we got a few blocks from home I noticed that the fuel gauge was off the full mark. The tank took 2 gals more than it should have taken; I drove 14 miles and consumed 3 gals of fuel. The engine ran great, plenty of power. My conclusion was that someone had stolen 2 gals of fuel during the night; I hate to entertain such an idea but there was no evidence of fuel leakage; I have a locking gas cap (I wonder how hard it is to get one open without breaking it? Master key maybe, lock pick?) The next fill-up produced 24mpg; the next one produced 13mpg. I have taken steps to secure my carport with a surveillance camera, but I am stilled nagged by the possibility that there must be another explanation for the loss of fuel.
Anybody have an idea? Should I make this a new thread?
