alright i have an older thread in here it was 2 blowen valves and a melted intake gasket problem my truck is pulling up a code p0300 and p0302 the only thing it is doing is idleing a little rouch when stoped and at slow speed acceleration when i hammer on the gas when you start of slow there is no problem at all i think there might be a problem with the spark plugs the ones on there are from napa and have hard problems with the last ones if anybody has any ideas please let me know i also think i have some bad gas in there a friend of mine added some gas from a gas cun but forgot to mention it used to hold pre mixed gas
