engine starts and runs good when cold but after about an hour or more of drive time it WILL (upon restarting) run rough, chug, almost likes it out of fuel. it only does this when its at normal operating temps.
engine chugs upon restart after long drive, is it a maf or crank sensor? on 1996 Buick Regal
