I have a 1991 Chevy Lumina van with a 3.1 liter engine. I was changing the plugs and messed up the firing order. I have found the firing order, but I do not know which spark plug connection on the distrubutor cap is number one, which is number two, etc. Please help if you can. Thanks.
have the same problem?
