Engine Performance problem
1988 Other Volkswagen Models 4 cyl Two Wheel Drive Manual 133000 miles
My Vanagon started to have very brief but sudden power loss - as if the ignition was turned off for a second - while running at a steady 45mph. The tach would drop to zero for an instant even though the engine speed didn't change much due to the manual transmission being in 4th gear. The problem got worse, lasting longer, sometimes I had to coast to a stop. The engine would restart and run rough for a moment, then be OK for a while. It happened again on a long downhill grade with no foot on the throttle and would not restart for 15 mins. Finally I had to get towed to a VW dealer and they can't find a problem!
On an earlier occurrence of this problem I replaced the coil, but that has not fixed the problem.
Any ideas? Many thanks, Jim
have the same problem?
