2001 Seville has a P0302 error code.

Hi, my first question, thanks for having me here.

This V8 motor that I'm working on, trying to troubleshoot this misfire on #2, sits sideways in the compartment. Can someone tell me where #2 is? I'm clueless on the layout of this engine.

Also, do these NorthStar engines burn valves?

@ 1969: I have been around a few forms a lot. I do enjoy some good entertainment.

@ BassCatt: Thanks for the info.

@ Submariner: Thanks for the details and direction.

My bad, the car is a Seville, I could not edit the post after making it. :/

It is a SLS. The plugs looked warn so I'm going to replace them along with the air filter and coil banks. The misfire is not constant but intermittent. I'll report back.
