I need a little help with my commuter. Ok, I race in a uh, Brand X (R -7)but my street car is an '86 Audi 4000S with the 1.8L K-Jetronic engine. I don't know a whole lot about Bosch K. The car keeps having this problem where the Blue Coolant level warning light comes on at the same time the engine power just falls off. It doesn't stall but can barely pull away from a stop light and the throttle is Very unresponsive. If I turn the ignition off and then restart the car (With the key or by bump starting it while continuing to roll) it returns to normal. It seems to do this while under power but not at idle. The engine still runs smooth but just lacks any power.
I am really stumped by this and would appreciate any tips you VW guys could supply.
TIA
Paul
