    So in the past two days I replaced some shocks and adjusted to gap on my spark plugs (previously .044) to the computer required .035 gap. After doing this, It was running just fine UNTIL I was at a redlight and decided to spin the tires and then it started sputtering hardcore during anything other than light acceleration and the engine gets real shaky. Do I just need new plugs or what?

    You said the engine was running rough, that should not make it pull either way, make sure a plug wire has not come off as you said you worked on the plugs.

    Were you power braking (holding the accelerator down with your foot on the brake) during your burn out? if so it could be a brake issue.

    I was power braking but would that cause the bad idle at 20 and sputtering at 60?

    1. Sputtering first
    2. then rear steer if you'd please.
    3. I talked to my mentor (grandfather), he says check the plugs for possible fouling due to contact with the anti-seize

    Could have something to do with fuel delivery also, there are quite a few things that could cause it to run rough, have you by any chance looked at the oil on the dipstick?

    You said you replaced the shocks did you replace the rear shocks?
