My guess is bad fuel pump or injectors.  |
My L99 hop's around on the Tach,about 100 too 200rpm's and talked too the Mechanic and he said its a lean roll cause of the lean fuel mixture and injectors need a few thousand k too seat,driving the bag off your new hot rod is not the way too break it in and suspect some of the problems are compounded from the driver ripping the bag off the car before its time too do so
