And you tried putting the old parts back in right? All of them?

What info are you using to make sure the wires are installed correctly?

i replaced the spark plugs, wires, rotor and cap,,, as i was replacing the cap and rotor i must have disturbed the distributor wires which got caught and broke when i tried to start it which made it run rough so i replaced the distributor. ran a bit better but still rough! i was stumped at this point because i was sure i had the wires in the correct order! so randomly felt the headers while running rough! 1 and 4 were hot while 2 and 3 were cold so i switched wires 2 and 3 and i was back in business ! runs amazing !

sry for the weak review im in a rush!

Well I am glad someone fixed there problem. Congrats, I wish I could find mine! I had posted the possible cause of two opposing wires still being crossed. After I posted I realized there was a second page so I revised my answer to this. I drove a Grand Am for a week with this exact problem. I got so frustrated trying to find the problem until one night it dawned on me. Swapped two wires and ran great. (At least for a year until the oil pump went out and the motor seized.)
