For the Rabbit, it wasn’t the injectors that clogged up, it was the fuel distributor. In other words, somehow the act of changing the filter can allow dirt and grit to get into the fuel line which exits the fuel filter and goes to the injectors. Failure to do so may result in accidental spraying of fuel, personal injury, or a fire hazard.

Fuel system pressure must be relieved before working on or disconnecting any of the fuel lines, fuel tubes, or fuel system components.

post filter) of the fuel system during the filter change. Even when the engine is not running, fuel in the fuel system remains under high pressure. Upon investigation, it was always caused by grit somehow getting into what is supposed to be the clean part (i.e. The engine would run much rougher after changing the fuel filter. I used to get this symptom frequently when I changed the fuel filter on my late 70’s fuel injected Rabbit.

You could either get a pro to hook up an ignition analyzer to your engine, or just replace all those parts and hope for the best. And changing the spark plugs caused enough movement in those parts to put it over the edge, and that is causing the symptom. You’ve got some degraded insulation or connections in the wires/coil packs/ etc in the ignition system. If so, I have two guesses what’s causing your symptom. I’m presuming you have no check engine light and no stored diagnostic codes. If this symptom only occurs when the engine is cold it could be a fuel pressure problem, but once the engine heats up and the O2 sensors come on line, I’d doubt a fuel pressure component to this. But it wouldn’t usually cause the symptom you are describing. It might show up as a “fuel trim” on a real time scan tool though. the O2 sensor feedback, will correct for a slightly high fuel pressure. In any event the feedback system your car’s computer uses, i.e. Your higher than spec readings could be an inaccurate fuel pressure gauge. But that would usually show up as a major fuel pressure problem, which you don’t seem to have. If there’s any gasoline inside that hose the regulator is shot. You might look inside the vacuum hose that attaches to the existing regulator. But no harm done – besides to your wallet – to replace the regulator.
