i'm barely getting 300 miles per tank and have noticed a few others with much better results. i was wondering if it might be related to the plugs and the gaps. i was getting multiple engine misfires when the car was only a few months old. techs told me it was no problem. after reading a few archived posts about plugs and their job, i was wondering if maybe my stockies aren't gapped correctly or something.
BTW, only mods are suspension and DV.
