So one of my friends bought a GTIR yesterday. I came with him but wasn't able to drive the car because the owner ran out of gas. After which my friend who isnt the most mechanically inclined to me the car felt alright.f This friend bought it and we got some gas. So he let me drive it home i noticed a few things wrong. Obviously and one that i can help him fix is the alignment some small rust patches. The bigger issue we found was chugging while driving. so when you have the gas pedal depressed about an inch or 2 and just cruising the car chugs and hops a little, now this happens at all RPMs. when you push the gas pedal farther and accelerate it smooths out. Anybody know what this might be? Heres his spec list from the guy we bought it off of: Nissan Pulsar GTIR 2.1 4wd 270+ BHP Nissan Pulsar GTIR 1991 import. Fully forged by spec motorsport in Kent.
