'90 Golf faltering for a second. Transfer fuel pump?

... > What are your symptoms? Stalls? Or falters but eventually keeps > running? Very predictable or very intermittent? Thanks for writing back, Tony! :-) The engine may falter many times in a row, but it keeps running and it's totally unpredictable. This issue may not show up for like a couple months then do it non-stop for a week. This has been happening on and off for over a hundred thousand miles now. The relay #109 is in like new condition--replaced once. I took the car to many car mechanics --both VW dealers and independent-- but they didn't seem to have a clue about this engine problem. Nothing seems to be recorded permanently on the on-board computer. |

Somethings to check: - clogged fuel filter? - combustion air flow unbobstructed? - exhaust system not periodically clogged or broken? - any relationship to how full is the fuel tank? - wiggle the key in the ignition to see if problem goes away? (worn out contacts in ignition switch) - your fuel consumption/mileage reasonable? - any difference when engine under load or just cruising? - not sure if a diesel has vacuum lines, but if it did, any leak? |

Thanks Tony! I'll keep and eye on those things but this faltering issue is
so sporadic that it'll take me some time to check them out. > Hi, I'm afraid I don't know what to suggest, I'm not at all familiar > with diesels other than the theory on how they work.
