Re: Truck misfiring after sitting for a couple weeks

Don't be surprised if you have to get a tuner to straighten it out . There's a lot to getting a idle correct if it has issues . Mail order tunes , some times you win sometimes you don't . Sounds like some one turned the wrong o/2's off ( Just a guess ) . Normally you turn the 2 rears off and leave the fronts on . As for idle , just take look at some off the stuff you have to do to correct idle .
