the problems were it would run ruff at any time like a pluged fuel filter -- almost stall lose rpm -- then it stalled entering the x-pressway and wouldn't restart.


so i did this stuff


well its running --- like a volvo !!! what i did was test and clean all the grounds & cleaned all the contacts -- checked all relays --plugs&wires ,cap/roter -- gas filter -- crank&cam sensor and still it didnt start --- then i tested the power stage(the thing under the coil) both leads showed 12+v.and then i tested the coil by grounding a test lite too the frame and holding it 1-2inch from the coil tower and got no signs of spark-- the dealer seid the coil rarely go bad --- so i replaced it low and behold --vveeerrrrroooooommmmmm life. i hope this helps someone with a problem 850.
