Question about 1988 Volkswagen Fox

1 Answer

1988 Fox wagon

My Fox has 168,000 plus miles. I recently started it, drove a short distance with no problem. It gradually developed a miss to the point that it stalled and won't start at all. I do have some vacuum lines which are not in good shape. I loosened the incoming fuel line at the distributor and the resulting spray showed good pressure. My next test will be a squirt of fuel into the intake and check the coil for good spark. Any other ideas from those with much more knowledge will be welcomed and appreciated. Larry..gvplars@yahoo.com. I'll try to find my way back here to pick up messages...

    Thanks to bets73 for responding. My '88 fox has been in regular service, ie. not setting unused. The problem developed while driving, beginning as a noticeable miss which gradually worsened, until the car died. I was able to restart it but it would only run for a second or two and would die again. We towed it home. and now it will start cold, run, although not smoothly, at a high idle. As it warms up , idling degrades and it becomes necessary to rev the engine to keep it running. Eventually, even revving the engine fails to keep it running, and the engine dies. About midway through this painful process if the engine stalls it will restart if I pump the accelerator vigorously. Most recently I squirted fuel directly into the intake to get it started. After several attempts the engine got enough fuel to stay running until it began to warm up. I did go over the vacuum lines replacing several of the aged rubber sections and connecting one small plastic line which connects to the fuel distributor. The spark plugs were all cleaned, wires cleaned, checked, and siliconed, rotor and cap cleaned, dried, checked. The spark appears to be good. I can hear the fuel pump buzz and there is good pressure to the fuel distributor. I would have waved my 'magic wand, but we are unable to locate it. I was tempted, however, to substitute a 2.5 lb hammer, but thought better of it and walked away for a while. The lesson was not lost on my son. Thanks for your kind assistance...look forward to hearing more ideas. gvplarry@yahoo.com. gvplars@yahoo,com

    Have an 88 Fox as well that has been running fine - let it sit for a 3 or 4 weeks and it has developed a hard miss. Smoothes out somewhat between 2-3000 RPM but is still there... new plugs (#2 looked cruddy) new wires and rotor/cap (noticable burnt) installed. Still missing - almost seems worse. Stethascope to engine block doesn't hear any mechanical issues. Could one foulded injector cause this? "Feels" like one cylinder not firing...



    Any counsel on cleaning the injectors? How difficult is it?

Well i was going to e-mail you but , your e-mail seems to be invalid ....i would go a head and replace the spark plug wires, insure there are no major vac. leaks, and if it has been sitting for some time , check the fuel tank make sure it doesn't smell like kerosene , if the fuel is old it will "gel-up" and get thick, ...if the fuel is old (hopefully there's not much in it) just fill it up with a higher octane to "thin it" back out.
if non of this works let me know.
oh...and don't forget to rate this thanks

Starter good but bendix not catching flywhhel


You may need to use shims. Is the starter new? Was it replaced recently? Did it start grinding suddenly or did the problem develop gradually?
The bendix gear needs to be a set distance from the flywheel before it will engage properly. You can usually adjust the gap by using shims.

I think that you should check fuses for the gauges. But it might be a bad wire shorting out. I also have seen these cars to blow all the dash lights before. As far as the oil light there is a sensor that goes into the oil pan or the block that may be dirty or shorting out.

First thing is to disconnect the negative battery cable from the battery, next you'll need to replace the wire going to your starter, unless there is another problem in the ignition system somewhere this should allow your vehicle to start again. If you repair this and notice or smell anything like wires burning disconnect your battery cable again and list your findings here for further help otherwise good luck and hope this answer works out your problem

If it runs at highway speeds then I doubt it's fuel filter. I'd check the operation of the idle speed motor. Here's a link to a diagram so you'll know what to look for & what to do. just scroll down to your engine (fig# 2 ) & click on small picture to expand it.
