UPDATE: Well, I started checking some of the things on the lists provided. I started at the trigger points, and some noticeable dirt did come off on the card (had some alcohol on the card) for both sides. When I was putting the distributor back in, I noticed that it did not spring back as Jim mentioned it should. I also had a great deal of trouble getting it seated all of the way (I've had this trouble before). After playing with it some more, I noticed that even when I got it seated and tightened down, I could still give the rotor a good twist and it would give me trouble. I borrowed another distributor with questionable points, and a good condenser. It installed with no problem, and did have the spring back action that the other one did not have. The car started and drove, but ran a bit rough. Once I got it up to speed, it started to have the same problems that the car was having before, but it seemed to be more like it was further back in the process. In other words, it cut out a lot, but I could still drive it. The good news is that I got it home, and gathered some more information. NEW INFO: Well, it doesn't cut out at any specific range, but it seems to do it when the throttle is held in position... Not so much when it is being pressed down for acceleration. When it cuts out it's literally like the ignition cuts out. It smokes a bit then when it cuts back in, there is a big puff of smoke and it cleans right up. That makes me think that I am missing spark and the smoke is unburned fuel. I couldn't get a good idea of what color the smoke was... It was dark when I drove it home. I hope to get a little direction from this, and really dive into the system tomorrow. At least now it is at home, and I can spend some time on it. Thoughts on most likely place to start? Trigger points on this distributor too?

Okay, we love a challenge. ;-) First a couple of questions: What kind of gas mileage have you been getting, specifically is there any indication that the mileage has been poor? If so, I wonder if your system is running rich. There are a number of simple things that could cause this, including mixed FI parts. Your brain and pressure sensor should both be 311-B versions. Your pressure switch should have a good intact hose between it and the intake air distributor. You should be able to hear your throttle valve click just as it comes off idle and just as it goes back on idle. When you get in the car and turn the key ON, do you hear a relay click and then another click about 1 second later? You should. Your charging system voltage should measure 14.1-14.4V with the engine warm at med RPM and the battery charged up after a drive. Measure it at the battery. If it is less than 13.5V replace the voltage regulator with a Bosch 30 019. I stock these if you can't find them locally. Remove your distributor cap and grab the rotor. Twist it CW. It should turn and then snap back. If it does not, you should let be rebuild the distributor. Grab the rotor and wiggle it sideways. There should be no perceptable play. If these things are all fine, pull out the distributor and clean off the FI trigger points that mount in the bottom (from the side.) Use a clean piece of paper to remove any dirt/oil from between the points. If things are extremely dirty you should let me rebuild the distributor. Don't let paper fibers get caught in the points as you draw the paper out. Keep us up to date on what you find. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
