My 87 vanagon will not pass smog. It lopes at an idle, hesitates badly during driving and blows black smoke. It does not do this all of the time, it has progressivly gotten worse over the last couple of months. I looked the problem up in a book and it told me to: reset vacuum kick reset fast idle cam index reset fast idle rpm The book however did not tell me where these things are located or how I can fix them. Please help!

Dear cc_racer- There is only so much we can do in "do-it-yourself" mode. You need a professional mechanic to look at your 1987 Volkswagen Vanagon. Without proper repairs, which might not be cheap, your car will not pass inspection anywhere and it will continue to be a major contributor to air pollution. Good luck from Bovan.
How did you solve this problem?
We have had the same problem (with the added complication of being intermittent and being temporarily solved by turning off the engine and restarting). The two local VW mechanics have been unable to solve it. I suspect a faulty sensor signal to the ECU... have already replaced O2 sensor and fully cleaned air flow sensor. Replacing ECU did not help.
Please help.
