Having problems with your 1993 Chevrolet Lumina ?
#1 and #4 are not firing I changed the coil pack and still no change any ideas
\015 I changed the coil pack checked all the wires no fire the other 4 cylinders fire so i am guessing it is not the timing need some input\015
See 3 and 6 won't fire
You said you changed the coil pack and the wires but didn't mention the plugs. Try moving one of the plugs to a different cylinder and see if the miss follows it. It could also be the ignition module. (the thing the coil packs mount to.)
