my car runs for about 10 mins than it starts to miss than it backfires when i even slightly touch the gas. Its throwing no codes and im stuck. If i shout off the car wait a minuite than it starts again for another 10 min. Don't know if i need a case learn done or not. I switched the pcm from a 2000 to a 1999. Would this cause the problem???

Is your fuel pump resistor good? You can try to bypass it (remove the relay and put a paperclip between pin 30 and 87A. I had a similar problem when I first start my car with the L67 in it (except I found out I didn't have that resistor at all :rolleyes:) I bought a new one and the proble was fixed :)

I don't know where they goes on the fusebox. If you used the the GTP engine harness, the connector is behind the battery on the passenger side.

Or you can ask Brian on www.L67swap.com, I'm sure he knows the answer.

I hope it will cure the problem...
