1988 VW Cabriolet intermittent electrical loss
A more specific and detailed question would be helpful in assisting you. I owned one of these for over 15 years and just recently sold it. I might be able to help, just need more info. What conditions does this occur? i.e., at idle, while driving at speed, what do the guages indicate (there is a batter indicator in the instrument cluster and one just below the radio. Take note of what's happening before, during, and after the event. Typically it is always going to be a simple diagnosis once some info is provided. Good luck!

1989 VW Cabriolet wont start.
You will have to pinpoint what the engine is missing... Spark / Fuel /Compression.
All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.
Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Hello-How do you remove the
Do you have the assembly off the car? If you do, do you know anyone with a press? That will move the splines of the CV joint after you properly support the flange hub.
If not, you need the type of puller with a yoke that accepts the wheel bolts to attach it to the hub.
Then you can apply enough force safely. The hub is very tough, you can wind on a lot of force. If you are attempting to change a front wheel bearing you WILL need a press anyway. It can be done with BIG hammers but you risk damaging parts.

My car stalls out sometimes when I'm idling at a
Your throttle body is probably dirty,The throttle body has a hose from
the air filter housing attached to it,the throttle body is attached to
the intake phlenum.Take the hose off(its rubber with a clamp on it).Do
this with a cold engine, NOT RUNNING ! spray some carburetor cleaner
inside the venturi and scrub it with a toothbrush,on the side of the
throttle body there is a place where a cable goes into,twist the
direction of cable to open the throttle plate(inside the throttle
body),and continue to clean.Now put it all back together.What happens
over a period of time is the Throttle body gets clogged with carbon and
cannot breath at idle, the throttle plate when close(at idle)has a very
small air gap and cant breath when dirty.If this does not cure your
problem,then you will need to consider having your ais motor check.ais=
automatic idle speed motor.For this you will have to take the throttle
body off to replace it and the screws have been installed with locktight
and are tricky to get out.Hope this helps,I did not know what year or
make of car
, but its a common problem since the fuel injectors took the place of the carburetors.
- ** Be careful that any cleaners used are for Fuel Injected systems and are O2 sensor safe. Some Carburator Cleaners can damage FI components.**
a throttle body spray cleaner, such as one sold by STP, to clean the
throttle body, then starting up and revving the engine, may be enough to
dislodge the carbon deposits
and material blocking the airway. The original poster's solution is the
cheap and easy way to handle this problem of low engine RPM causing
stalls. Try it first, it is a fast fix, and it worked for me, causing my
engine RPM to go up above the stalling level when my car was idling at a
stop sign or red light.
