1999 Pontiac Grand Am 6 cyl
I have a chugging enging at low RPM such as at a stop. I changed the plugs, wires and still a problem. Auto code shows #1 not firing so I changed the coil and still not better. In addition I looked up the firing sequence and was told it was 1, 3, 5 front from passenger side in, and 2, 4, 6 firewall side from left to right. I traced each and the front came up 1.3.2 in the front. I replaced all wires per the information above and the car would not even start. I put back to the original 1.3.2 and now back to the original problem? Can you help and also tell me the correct wire sequence?
