Question about 1990 Volkswagen Fox

1 Answer

1990 Fox Drops to Slow idle speed after 10-15 minutes Driving

Engine starts fine but looses all power, but continues to idle slowly reguardless of throttle position. I suspect the j-tronic injection or oxygen sensor. Does this have a computer and how do I read codes? Any info on fuel injection?

I had the exact same car, and almost the exact same problem, it was the Mass Airflow sensor, you will have to get a new one, or look in the forums for a way to modify it, there was some problem with it fouling, it was really strange. But also, if it was even drivable, it would lose all power within about 30minutes. I hope that helps

Fuel injection needs 20-30 pound pressure to fire the injectors. Try to check pressure before filter. If its low your pump is no good. If its ok then you have pressure drop after the filter. Filter on backwards or clogged.

I have a 1990 vw vanagon it will shut off when at idle, once it is warm it idles fine


Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Loss of power and drive but engine is still running


The water bubble under the dash might be a heater core, and the slow and sluggish might be caused by the transmission, try checking the wires and plugs, they may need to be replaced, we just changed out the wires and plugs on ours and it did wonders!
