Just got the P0301 code on the way home tonight. Truck started to run rough, and the SES was blinking. I'm parking it until morning, as it's 110*F out right now. Hopefully, it's just the plug and/or coil pack.
Spark plugs were overdue (I'm at 120K miles), but they didn't look bad - just old and somewhat worn. I was hoping #1 spark plug (passenger's side front plug) was going to be looking really crappy, but it looked like normal wear:
Truck will not start. Too hot out to mess with this now. In the morning, I'm going to spray some starting fluid down the throttle body to see if that will help (maybe a fuel issue is causing the no start condition).
Ted, I would try swapping the coils around to see is a) code changes and b) to see if you can get her to start up. You probably just have a bad coil (cylinder 1)
