auto...
seems to be missing as if one cylinder not firing. no check engine light, but very rough idle. runs fine once rpms pass 2000...if sound is any indication.
question is do the coils go bad? and whats the best plug for the coil on plug design? also i assume the timing is controlled by the computer so this could also be a timing issue, but then things seem to get more complicated like sensors and such...trying to narrow down with easy first.
thanks in advance

Maybe not the best, but Champions run fine. The coils are quite long-lasting. If your misfire is only one cylinder, then check the plug. If it were a coil, you'd probably have two cylinders missing.
