I have a 1993 VW Fow that runs great. About once or twice a month it will be running just fine when all of a sudden the engine will stop running, a second later it will run causing the vehicle to jerk violently then the engine will die. When trying to start immediatly after this happens the engine will turnand sputter as if it wants to start but is being sufficated.
I have found that when this occurs I will undo the latches on the air filter compartment ,reach up into the air filter compartment housing and work a flap back and forth corrects the problem and the vehicle will run great until I need to do this agian.
Is something getting stuck? What should I replace? Is there something I can do to recreate his problem for a technician?
thanks
