Question about 1992 Volkswagen Passat

1992 Vw Passat DOHC 2.0 liter 16v

Hey Guys,

My '92 Passat 16v has intermittent problem. When the car starts no matter when it is hot or cold it is sputtering. While it is idling I can give it gas at 3000 rpm it clears up then does the same when it idles at normal speed.
BUT sometimes it idles fine.

If I drive the car I have a large amount of lost power, misfiring etc. But then it will clear up at higher rpm's then come back at lower rpms. Sometimes it is completely fine for few miles.

I have changed ONE AT TIME:
External fuel pump
Fuel Distributor
Fuel pump relay
Fuel pressure regulator
ALL four injectors and checked the cold start valve for leaks
plugs wires
cap and rotor
coil
Distributor
ECU

I haven't changed the internal fuel pump but I am going to on Tuesday. Can it be the problem? What about knock sensors? The car isn't knocking or pinging. PLEASE HELP!!!

92 vw passat 2.0 16v wont start.


I bet it's the gas. After some time the gas will no longer be volatile enough to start the car. Try draining all the fuel and putting in some fresh gas. Remember, when you try to start it again you'll need to get the new gas through the pump and lines before it will start. Also, check the condition of the injectors. Old gas can start to break down and build up a film that could be on your injectors (or clog your fuel filter- better check that too). Hope this helps.

92 vw passat , won't hold an idle on cold start, slugish acceleration, seams to have a slight miss fire , any ideas ? thank you


I'd check the coolant temperture sensor, also check for a vaccum leak, disconnected or broken vacuum hose. See my "How To" to find a vacuum leak.

VW Golf DOHC 14i 16V, hunting, starts and stops


There is a small vacuum pipe from the EGR solenoid that was disconnected, by reconnecting this pipe the problems (that I have had ever since I had a new head some 30,000 miles ago from a VW main dealer) have gone away.

Probably the starter needs to be replaced. If it was the battery, you would have more problems cold than hot.
