there is really alot of shit i could be. i know if you turn the turbo up to much they have a fuel cut out but its nothing like your talking about. if you think about it everything on that car is around or over 10 years old....how does it idel.....im pretty sure that if it was the MAF it would idel really bad. it would start around 1k and keep bouncing up to 2 or 3 k over and over again
