I just got my 91 oct. mark d chip today. I installed it and when i started it up it idled really rough at about 400rpm and then died when i tried to back it out of my driveway. Tried a few more times and the same thing happened.
I figured it was crap so i put my stock chip back in and it kept doing the same thing, idled rough then died. It was running perfect before i put the chip in. Any ideas as to what happened?
thanks.
