perform a complete tune-up. This means: spark plugs, spark plug wires, dist.
cap, dist. rotor, air filter, fuel filter. Check your ignition timing and
throttle switch adjustment as per Bentley. If it still persists check for
tears in the intake boot.

Remember to use German parts. I wont say how adamantly I feel about using
high quality parts due to potential flaming ;)
