Hello,

I have a 1984 1.9 Transporter. It is bucking at high speeds, = around 60 m.p.h. after a highway drive of about 30-60 minutes.

I took this problem to a good Vanagon VW mechanic, who is a list = member and, for free, he tried a few things. He cleaned the grounds. Well, = for three weeks it stopped. Then, out of nowhere, it started again.

It used to only take 8 minutes for it to begin, but with the = grounds cleaned, it seemed to have helped.

He checked the AFM and it seemed to be okay. HE gave a quick = checkover of the engine and didn't see anything out of place. I even disconnected = the idle stabilizer and bypassed it, nothing.

Any ideas? I need this van to okay for a 3 hour trip to Herhsey, = PA...I am going to a concert and seeing friends from my home in NY.

Any ideas?
