Especially for the air cooled engines you should not really be doing extended climbs at low RPM. Down shift and let it rev. Lugging (when increasing throttle does not increase speed) causes this engine to heat up quickly and low rpm also means low cooling fan output. You need to determine if your problem is loss of fuel or ignition. I believe your 80 still uses ignition points and condenser. A bad condenser can cause loss of spark and be affected by heat. The loss of spark from the points-condenser also effects the operation of the injectors. For the auxiliary air regulator these hardly ever go bad. Check to make sure it is in fact getting power and check its resistance to determine that the heater is not open. Be sure the wiring is not switched with the cold start valve or thermal time switch. This device was used on a lot of vehicles. You should be able to get something close or a good used one.

Initially this was mainly when the engine had been working hard; i.e. prolonged climb at the low end of the RPM range. Now it's beginning to happen more frequently and under a variety of conditions. When it stops if you let it set for 10-15 minutes it restarts and drives fine for an undetermined period of time (now getting shorter). I've replaced the fuel pump, fuel filter and most of the hoses on the fuel and intake system. Any suggestions on where to look will be greatly appreciated. I've also found that the auxiliarry air regulator is not full closing when it's warm. VW says that this part is no longer available. Any suggestions on how to by-pass this part or other work-arounds. |
