Question type: Maintenance & Repair

I have a  2004 Dodge ram 1500.   Truck is
misfiring only when driving with a load.  Idols
100% fine. Already replaced wires and
plugs.  There is also no oil on the plugs. I
had it  Scan and there is
no code also, nothing showed on the
cylinder misfire calendar. I am stumped and
have seen nothing on the internet relating to
this!! Please help

Odd you wouldn't get a code of some kind, something you might try is putting a can of SeaFoam in the fuel tank and drive it as you normally would, it is possible that you may have an injector that is slightly plugged and only shows up under load, if that works then the next fill up should be either Chevron or Texaco fuel as they both contain Techron, it is a very good everyday system cleaner, then you can go back to using top tier fuels and just add a bottle to every other tank to keep your system clean.
