Hi all, For the past week or so, my '89 Westy has been suddenly loosing power (and then immediately regaining it) repeatedly from once or twice over a ten minute period to 8 or 10 times a minute or more. The power loss makes the whole van shake as if I have hit a large pot hole and I have noticed that while this is happening, the tach can drop 500-1000 rpm. Now, I know that when I'm driving along at 50 mph in 4th gear and have an instantaneous power loss that the engine can't possibly be dropping 1000 rpm. I have not noticed a relationship between engine temp, weather conditions, drive time, etc., and the power loss yet. It seems to behave differently every day. It had been doing it after the engine was warm for a few days so I did the Harold and Nancy "Vanagon Intermittent Syndrome" fix with the Tantalum capacitor connected to the AFS and the next time out, it only lost power once on a 10 min drive, but, this morning, I didn't even get out of my driveway before it started doing it every few seconds. This afternoon on my way home, it didn't start until after 5 or 6 min of driving. I have recently replaced the Temp II sensor and OXS to try to fix my low idle at start-up, high idle when warm problems. (That hasn't helped by the way, but I can live with that much easier than this latest challenge) TIA, Roger |
