Forgot to mention it's an automatic and it's just basic car. Doesn't have turbo or anything like that.

I did find what was causing the other code (P2076) but to start working on the P0301 code, I really just need to know what the firing order is.

I'd like to be able to start on it tomorrow morning.

So is there anybody here that knows this, has a screen or anything?

Or can someone tell me what to Google search to find it myself?

Cylinder #1 is the one closest to the belt on the engine. Be careful getting the coil pack off as the boots tend to stick to the plugs. I would highly suggest putting dielectric grease on them before reinstalling the coil pack to make removal later a lot easier.

Thank you, this is everything I needed right now.

Just got done taking it apart to find some previous "mechanic" somewhere used electrical tape to fix a torn boot.

Could this cause a misfire?

I had trouble getting coil rack out and had to remove some of that tape to get it back in without fighting it too much.

Then the spark plugs loosened with no effort whatsoever. Nudged with my thumb just barely and both screwed right out.

Not sure about the condition of these plugs. Looks like it's been running lean?

The plug in the socket came out of #3 and the other plug on the left is from #1.

I switched the plugs around to see if the code changes to a P0303 but doubt it.

Is it even possible to switch the coils around?

Looks to be a permanent 4 coil unit.

If not, how can I test the individual coils?

Electrical tape is good for about 600 volts. I am not sure, but I think the coil puts out much more than that. Remember to put some dielectric grease in and around the boots before installing them and a touch of never seize on the plug threads couldn't hurt either. :2cents:

50,000 volts. But i think it's come down lately. 25 or 35,000
