Hi im ben from michigan. i just bought a 1998 gtp and it needs some tlc. heres the problems. it gets an average of 15 mpg driving around and smells like fuel at exhaust at an idle and also has a roughf idle. the other problem is the supercharger when it would hit boost on the gadge on dash it would cut out the motor, like miss real bad so i took the belt for the super charger off and all that went away runs great just smells like unburnt fuel at exhaust and idle miss and poor miles pere gallon (15) any idea's?????? any info would be great. also the cars check engine light dont work AT ALL. lol iv checked it when you turn ke on and all others things to get it to come on and it wont, i can see it in the dash it just wont light up. weird as heck. but i got the car cheap and man is it awsome nice leather great audio very comfterble and the car drives itself. I love it. well anyway thanks for any imput you guys have and i will get this figured out and post all changes unlike other people who get the car fixed working great and never come back to post what did the trick.... thanks again
