hey guys i think i put some bad gas in my jeep... i am just getting to where it will run and not knock and ping too much... i now can give it gas and it will not die... i put some stp gas treatment and some more superconcentrated stuff to help plus a gallon of 93 octane (i have about 2 gallons in there now)... on the OBD II i get this
PO300, PO302, PO303 --> multiple cyclinder misfire...
i know i need to change the plugs becasue they are probally fouled up... what else should i do now? will i know if the o2 sensor is bad through the odb? it still smells a little funny and does not accelerate 100 percent... any thoughts about what to do next? should i add somthing else to the gas to help clean it out? acetone? also i am installing a new catalytic converter, car sound magnaflow 2.5 universal b/c my random cat is all banged up- too but it ran fine before i added the foul gas
what are my next steps?
