Hello everyone. I just bought my first GTP and was wondering if you gurus could help me with an engine surging problem. It started today as i was driving down the highway. I went to pass a slower car and accelerated normally. I barley got into the boost (maybe 2-3 bars) and felt the car start to surge. I noticed the boost guage was going up and down by 1 bar and the rpm was surging up and down approx. 200-300rpm at part throttle. after i noticed this i stomped it to the floor and the boost guage went full sweep but was still surging a bit (i.e. the last bar on the guage was coming on then going off with the pedal smashed to the floor). As far as i know the car is all stock except for a set of MSD wires. oh yeah, it's a 99 coupe. i have not scanned it yet but there aren't any SES lights yet. thanks in advance
EDIT: this car also has idles kinda rough. the rpms don't change (about 750) but the whole car vibrates. maybe i'm to used to my truck
