I have a 1994 EA82 installed on a VW bus and I have a problem with idle speed, maybe someone could help to find path of the problem.
The idle is too fast, I don't have RPM but I would say around 1200rpm, here is the steps that I have validated
* Butterfly screw is just above the butterfly mechanical contact.
* Idle screw don't have any effect on the idle speed
* Idle switch working
I have performed the timing last week and I was able to adjust the idle by the screw at 750rpm for proper timing with test mode jumpers on.
What else could overide the screw ?
thanks for your input.
