88 Mercedes 420SEL misfire off idle/ under load
I'm working on this 88 MBZ 420SEL. When hot, & under heavy
accel from a stop, it intermintently
misfires/hesitates/sometime backfire at around 1200 rpm
only. If the car is moving, acceleration is perfect. Idles
perfect, & drives great otherwise. ![]()
