So i’m looking at picking up a parts car. I found one on Marketplace, description states it has low compression on cylinder 2 & 3. After talking to the dude for a while he says it is also on E30 but is not tuned? (Not sure if this guy doesn’t know anything about the car or if it’s really not tuned) He says it runs and drives but has zero throttle response and you have to have the throttle to the floor for it to start moving. Would a full rebuild on the head be needed or could this be a quick and easy fix? I’m assuming part of the throttle response is due to the E30 but I believe it still will most likely need a rebuild.
