Ok so for the last 2 weeks my r/t has had this wonderful cel been checking plugs wires injectors cap and rotor cam shaft pos sensor tps . So now I'm wondering after searching a lot on here and not finding awnsers has anyone figured this problem out yet. I have checked everything I can think of and that any of the other posts on this have suggested has anyone figured this problem out?

 

what do those codes mean? If its bank 1, catalyst inefficiency, and misfire in a cylinder then its probably a bent valve or cracked head.

 

300- random misfire
302- #2 misfire
308- #8 misfire

 

Yeah I already thought about a burnt or bent valve but if that is the case wouldn't the problem be more consistent rather than here today gone tommorow it seems to do it when I don't let the truck warm up enough to its standard and not mine and the weather has changed considerably.

 

yeah it would be there all the time. but it could be a head gasket going bad that leaks when it's cold and then seals up as it expends.

 

now that does make some sense zanethan , how could you tell w/out having to pull the head off ? if it wasnt my daily driver i wouldnt have any problem pulling it but being in the army and it being my dd i dont have that kind of time.

 

Maybe a compression test would give you some better answers I really have no clue how to test it other than that though.
