i have a full tank of gas, truck is stalling out when I drive.

Yes. Since I wrote this I had a new oxygen sensor put in and 3 relays. Check engine light was off for 3 days, and it's back on now.???

3 relays went out at one time,and an 02 sensor?what codes did you have then,and what codes do you have now?

I'm don't have the paperwork on me now, it's with a friend of mine who is a mechanic and he is checking it tomorrow for me. When I get that information, I'll put it on here. Thanks for your help!
