So much for the newest revision coil pack, I just blew cylinder number 3 before even making it out of the driveway. I'm googling but cant find a diagram for cylinder numbering. Which cyl is which?

 

Note: Cylinder #1 is closest to the radiator, and cylinder #4 is closest to the firewall. This should make finding cylinder's 2 and 3 self explanatory
Im not sure about the cyl. order on 2.8/3.0, etc. But Im sure its similar with 1 and 4 being the closest to the radiator.

Thanks, I lucked out and guessed that numbering, and lucked out picking the good coil packs out of the box of bad ones (1 I knew was bad, the other three were 2good 1bad, so the odds weren't horrible).

My next question is, why the hell do these things blow so easily? I started it up and let it idle for 30-45 seconds before the CEL started flashing. I blew two packs right after getting chipped (cyls 1 and 2), and replaced all 4 with the latest revision pack. This one blew in less than a tank of gas on cyl 3. These things should be recalled.

 

probly because you forgot to regap your spark plugs after getting chipped

 

im gueswsing the 2.8s are diffrent but mine says the firing order on the front of the engine.

 

I must have missed that thread. Why would one need to regap the plugs after getting chipped? Longer duration discharge?
