Spark Plug Strange ?

Hey guys ,


Just a small question, when I changed my spark plugs (AutoLite Platinum's) and Spark Plug Wires (AutoLite Professional Wires), I ran Coil Pack #1 (Cyl 1&4) with Terminal 1 going to Cyl 1, Terminal 4 going to Cyl 4, and same for Coil Pack #2. The question I have is what would cause the car to run smoother by swapping the 1 & 4 wires, but keeping the 2 & 3 the same. I found one diagram on google images that mentions switching them, but I thought the coil pack numbering corresponds with the cylinder numbering? When I do 1 to 1 and 4 to 4 the car shudders, and yet when I swap them it is smooth. Explanation? Any explanation would be appreciated !

First when trying to figure out wiring always check your grounds. Are you sure they were hooked up right to begin with. Perhaps someone had swapped them and you just corrected the problem.

And also make double sure of the firing order corresponds with the coil pack the firing order for this engine is from left to right looking at the engine 1-2-3-4

The only other thing I could think of to answer for this is messed up wiring I would change the coil pack to see if it is still the same or if having a new one changed it all together.

This is really difficult to diagnose because this usually will not happen as you have pointed out.

And it could just be something GM messed up and by switching them you correct a problem from the factory. Although this is unlikely it is still possible.
