2007 2500hd P0430 And P0300

[tcalb2]

I have a 2007 2500hd 6.0 and it has only 75k and out of nowhere it started to show check engine lights, ran fine up until then. I had the p0430 and p0300 codes when I scaned it. I replaced the 2 Oxygen sensors in bank 2 and all new plugs and wires. Cleared the codes and they came back a week later when I was on the highway now it rough idles again and feels like its got no power, very sluggish. I have to mention my fuel gauge has been broken for a while now, when it reads 1/4 tank its actually out of gas not sure if that matters, thanks

You have a 5 year-100,000 mile warr. Take it to a dealer.

Yea I bought the truck used so I wasn't aware of any of the warranty stuff. Is that just on the emissons system?

[LeoS41280]

The warr transfered to you. I'm not sure about the emissions.

I just left a message with the local dealer about the warranty, I'll have to wait to hear back.
