Question about 1996 Chevrolet Cavalier
I have had the car in the garage since I can't get to the coil packs. After replacing the coil packs and module with new or known good ones it seems that 1 & 4 were not getting a signal from the computer which some clown located in the wheel well on the right side. After cleaning up the connections and re-gelling them they reassembled and the car ran fine for a few day and then back to the same problem. Somewhere in the wiring has to be a bad connection, frayed wire that sometimes connects and sometimes it don't.
The computer was replaced with a new one and with one from a car that was working fine and still 1& 4 wasn't working. I drove the car away this morning to bring it home to do the troubleshooting as it was cheaper than $65.00 per hour for the garage. They pointed me in adirection to start from, but I need wiring diagrams to assist.
Has anyone else had a wiring issue? Also the exhaust system is now dragging...any supports it had are gone... does anyone know where the original brackets should be other than the muffler?
The engine computer can tell the ignition module to change the timing but it doesn't control the spark , the module does. So if you are loosing spark on 1 and 4 it is not the engine computer or the wiring going to it. The problem has to be a plug, plug wire , coil, or ignition module. The reason you loose 1 and 4 is because they are both on the same coil. If the plugs and wires have lots of miles on them, I would change them first. DIS system have to fire what is called a waste spark, if you have a plug or wire with high resistance it will cause a miss on the cylinder it shares a coil with. If that doesn't help then I would switch the coils and see if the miss moves to 2 and 3.

See Figures 1 and 2
To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.
