Well, I'm about to give up trying to solve my rough idle problems with my Vanagon. I adjusted and replaced just about everything I can think of.
Are there any good Vanagon Mechanics in Texas? Brent, what about your dealership? The guys near Arlington, German.....?
I have either adjusted or replaced:
- AFM w/Signal Filter Circuit built in - did fix the hesitation on take off problem
- Throttle stabilization valve
- Throttle control unit
- O2 sensor
- Injectors - did fix the black smoke problem
- temp 2 sensor
- cleaned grounds, replaced ground strap
- cleaned all electrical connections
- ECU - with spare I bought at the VW classic - actally made a Van-CAFE ECU monitor, but it doesn't help.
- Throttle
position switch
Any ideas?
