I recently purchaced a 1987 Volkswagen Quantum... the car was in good condition except had some mechanical problems... What I am running into right now is the car will not rev past 3000 rpm and has no power... it is also blowing black smoke out the back... when i got the car i repaced the Pugs Wires Cap and Rotor, I also replaced the O2 sensor... and the problem still persists... I whould like to get this car running for when i had it on the road it drove like a dream... any help here whould be apriciated....
Thanks
