ARE YOU A-GETTIN' THAT SULFUR SMELL?

BETTER HAVE THE CATALYTIC CONVERTER CHECKED FOR BEING PARTIALLY OR STOPPED UP. THIS TOO WILL MAKE IT SET A P0308 CODE

FROM THE SOUND OF YOUR SYMPTOMS, I'D BET ON THAT BEING THE PROBLEM!

KEEP US POSTED ON PROGRESS!

Have a pro diagnose this as the 308 coe is a misfire and it can be an injector/fulepressure, maf sensors. He can scan it an duse a mode 6 to find the problem to correct it.
