Re: '87 5KCSTQ Idling Problem
I can't seem to find the procedure for cleaning or testing the idle
stabilizer valve. Can someone point me in the right direction or mail it
If the engine is cold I get the same problem upon startup. It starts to
idle at 2800-3000. If I give a little tug at the throttle line it goes
down to about 1100 but its still idles kind of rough. As well, the fuel
distributor is making a: bzzzt (stop) bzzt (stop),... continually. Is that
