Can someone please let me know which is Coil "G" and does the lettering system follow the cylinder number (A = 1, B = 2, etc) or the firing order? And also, are the cylinders numbered front to back like a small block Ford or left to right like a Chevy? Many thanks of course.

I replaced all ignition coils about 2 years (<10,000 miles) ago with new but cheap Chinese coils off ebay and a couple of weeks ago I started getting a PO357 Coil G Error Code, then a Random Misfire Error code. I decided to take it to a local mechanic, thinking it might be a wiring issue, and they replaced two coils themselves. Two days later I'm getting the same Coil G Error Code again. Any Thoughts? Again, thanks in advance. Gene

Thanks for the links. I'm going to swap F and g and see what happens.
