Question about 1990 Volkswagen Cabriolet

1 Answer

1990 cabriolet manual transmission. Car stumble and looses power

When applying pressure to the gas pedal it will loose compression and choke instead of accelerating

back fires

after driving it a short distance it will not start back up. it will turn over sounding like it's about to start but will not catch.

if you wait 10 minutes it will start back up but still run ruff.

can anyone help me?

also does anyone know the proper firing order or spark plug order..
this has brand new sparkplug dist rotor cap wires etc

a little backround: the car has 110 xxx it was stored in a garage for 6 years. iv had the car for 6 months. it was running ruff for the first 2 weeks. then i did a full tune up. the # 4 plug was flooded with gas and I had to replace the fuel injector sensor / relay. after that it worked perfect. The car also currently needs an exhaust manifold gasget so it runs a bit loud and ruff.

    i took the cover off the timing belt and somewhat did a notch test and it seems to be fine. the belt itself is almost new. i was thinking maybe a fuel pressure regulator or air sensor. I also swaped out the platinum spark plugs for standard mgk. and swapped out the dist rotor wires and air filter. it starts up but boy it's running ultra rich! also still ruff and backfiring. i also double checked the firing order of the plugs all it correct.

    im wondering is there a way to you can suggest to check the belt timing?

When i give the car gas in wants to stal out and wont go

here are a few things that can do that to a car, the first and most important is the gas pump which could be breaking down, loosing psi. Secondly your plugs might need to be changed, etc plug wires. And the last thing is if your electrical wiring is damage it could cause current to break down while the veichle is driving causing it to stall .

Three of your EGR intake ports are likely blocked up and need to be cleaned. The one that's free is receiving too much egr gas and that's what causes the engine to stumble. It's a common problem, but one that's usually misdiagnosed, with that 2.2L Accord engine. Have the ports cleaned out asap or the cylinder one that's getting all the excess egr gas will burn out it's intake valve and cost you much more to repair, requiring the engine head to be removed.

This is timing slop, when you take your foot off the gas pedal, the timing chain or ignition has no more load and gets loose and the timing changes.

Car losing compression

I doubt u are "loosing compression" more likely a sensor failure is causing a loss of power, go to any Kragen or Autozone and have them run a OBD 2 trouble code test, it is free, then post the code back here.
