Thanks for the add. I bought a 1998 Chevy dually crew cab 2wd with a 454 about 2yrs. ago and have been just driving it to get a feel for what I want to do with it. Right now I’m having some drivability issues. Running rough at idle, lack of power, engine missing when giving it the gas and small backfires through the muffler on deceleration. I’m not sure if it’s a fuel problem or an ignition problem. I did change the cap and rotor and it improved for a little while. Can the group point me in the right direction as to what I should be checking first? Again thanks for the add. I’m going to love this forum.
