Troubleshooting / Re: 1981 Vanagon Diesel Surging idle
« Last post by fatmobile on May 27, 2024, 11:52:15 pm » I've had the RPMs hang and rise when the max fuel screw is in too far.
I think most commonly it was caused by a pissing injector.
Fuel doesn't burn well and remains until the next time around, where it's added to the next squirt.
Lots of white smoke?
And I'm going to mention that sometimes the pump can be put on 180 degrees out.
Not sure how, but others,.. and I have done it, long ago.
Maybe air in the fuel, do you have clear lines to and from the pump?
