Hi Guys
My 87 930 starts great and after a short warm up, I take it out, after about 2 miles it starts to run ruf, like its alternating between 4 and 5 cyl, the tach also bounces and goes to about 5000 when its barley at idle, seems like it wants to stall, I limp home and scratch my head.
The head scratching I can deal with, anyone have any ideas where to look for my problem, battery has full charge and the alt is putting out according to a test that I preformed from some other advice I got here.
