so i bought a 2001 gti with all the upgrades already installed. just as i drove it home like a 30mile drive the engine light came on, so we brought it to the dealer and they didnt know what was wrong. so i was driving it and all of a sudden it started jolting and than it wouldnt alcellert good, if i was supposed to be in 2nd gear i would have to put it in 5 gear to move with out it jolting, and than when it jolts it dies at every stop sign. so we put about $3000 trying to fix it but it never was fixed the place we brought it to has no idea what wrong, they put a new chip in it and programed it. if anyone has any idea whats going on please help out
