Threw a code this evening - going to get it checked tomorrow @ Autozone - will let ya'all know what it was. Odd - just driving along, looked down and my old friend the orange engine was back! My money is on the crank position sensor .... if that's the case I'll pull the connection, clean it, hook it back up and see if it comes back - if it does I'll replace said sensor.

Cheers
Steve

Oh - no more backfires -

 

Don't go by the "description" of the code. Get the number, then first Google it then do more research.

I still don't know how a fuel injected engine backfires. Oh, a burnt intake valve?
