Question about 1987 Volkswagen Jetta

1 Answer

Push the accelerator, nothing happens or falls on face and dies

I have a 1987 VW Jetta. I have a difficult time getting it to start and stay running and when it does eventually stay running, I push the accelerator and either it doesn't do anything, or it falls on its face. Also, sometimes there is popping sounds coming out of the hose that comes out of the fuel distribution center. There is also a screw under the accelerator cable that seems to control the idle a little bit (air mixture screw?) I can hear air when that screw is turned loose a little but if its tightened all the way, no air sound. I don't know where that is supposed to be set, though I know the car is supposed to be around 1000 rpm plus or minus 50. No matter where I set that screw though, the car never makes it past around 750.

    It doesn't have a carburetor, it's fuel injected and I have already done the carb cleaner thing around the hoses and stuff.

You might have a vacuum leak just get a can of carb cleaner the spray kind not the foam stuff and spray it around your carb and vacuum lines and see if anything changes.l

All the above problems were happening to my truck, and the engine light never did come on. Finally changed the O2 sensor, and it runs like new again.

start procedure is to hold accelerator half down, turn key, wait for injector light to go out, then hold down clutch pedal and start. do not pump the gas. just hold it 1/2 down. when car starts, release gas and then rev it up until the alternator light goes out.

Have you checked the charge on the battery? How bout your connections at the terminals. Vw are very sensitve to voltage drops. You might even have something thats draining your battery

1987 VW Jetta won't start. Starts occasionally when you jiggle the gear shift. Replaced the contact bridge and soon will be replacing neutral safety switch. If this doesn't get it started, what should I do...


I have an 87 Jetta also. The problem is basically that the electrical wiring throughout the car is getting brittle and the wires rub against metal and other items on the frames (sometimes sharp edges are involved. Once moisture gets under the wire insulation, the braided wiring begins to corrode and resistance to current flow increases over time. This has effected everything from the radio to the headlights in my car. Starting the car with the ignition switch got more and more difficult.
Then, I simply got a starter button from autozone (about 15 bucks), wired it with new 10 gauge wire directly to the starter and the battery and mounted the switch on the left side of the steering wheel on the dash (eerily there is a perfect mounting place for it). For the last 4 or 5 years, I just turn the key to the on position and push the starter button and it cranks reliably every time. Some day when I get time, I will run a new hot wire from the battery to the main fuse block under the dashboard. In the meantime, the car starts and runs great.

Clock/Mileage gage stay on even when car is off.. Is this Normal?


I have a Jetta 2005 and I just noticed that after this:
when my battery died after 7 hours playing my stereo, then I charged it for 30 minutes and my car could start on again. After that incident thet remote key started failing when I push the open button twice to open all doors. They remain closed, only passenger door open. Then I disconnected battery over 15 min to reset computer, and the clock and mileage gage remain on all time after that. Never remain on before it was disconnected and conneted again.
