So a week ago my truck wouldn't idle so after taking it to auto shop at school we figured out it was the fuel cut solonoid(SP?). After taking it out we found a metal shaving in it so we cleaned it out and it would idle. But now when I turn it off it trying to keep running. We messed with the idle screw but it still does it. Can someone please help? By the way it's a 22R in an 86 Pickup with nothing done to the motor

There is a small o-ring at the end of the fuel cut solenoid, if its missing that will cause the dieseling that your getting, if the o-ring is there and your still getting the dieseling problem then the fuel cut solenoid might be bad and turning the fuel flow off when you shut the engine off. I went through this same problem on a 22R that i used to own.

where did you get the new fuel cut solenoid?

sorry for the hijack, but isnt that how the fuel cut solenoid is supposed to work? kill the power, it cuts fuel?

Yes, thats how it is supposed to work, but if the o-ring is missing then fuel can still get around the fuel cut solenoid and cause dieseling.

If i remember right the fuel cut solenoid was a bit expensive new, but i was lucky enough to find a used one. if you have a pic n pull near you then you could probably find one there.
