Hi,

I attached three pics. Pics 1 and 2 shows cylinder locations. Pic 3 shows where the wires attach on the coils. Pic 4 shows the cylinder locations from a top view.

Let me know if this helps.

Your information was very helpful in confirming the wiring connections.
However, the car would take so much to turn over and ran so badly that I decided to check over everything I did. As I removed each plug individually, I noticed that 4 of the cheap plugs were badly damaged: cracked, shattered and one broke off from the metal.
So I replaced the 4 destroyed plugs with new ones and kept the 2 that weren't damaged. The car started and ran well.
The next day it started to misfire and it even cut off in traffic. So I am going to change out the remaining 2 plugs from the cheap batch and each of the coil packs just to be safe. Once again, thank you for you very helpful diagrams and info.(I have no idea why the cheap plugs got damage like that from cranking the engine. When I put them in they appeared new; maybe they weren't).

Wow, what kind of plugs were they? I don't want to get that brand. LOL

Let me know if the other two fix the issue.
