Engine will start, but not run, unless you hold the throttle open. Runs normally with slight throttle application.

When coming to a stop after running, will die (often with apparent "electrical failure", i.E, the radio time resets, all electrics go blank momentarily).


Problem has been intermittent. Sometimes waiting a few minutes will allow it to start normally, and idle normally, other times will immediately shut off after starting (unless you hold throttle open slightly).


Again, once you open the throttle manually, runs normally.

Cleaned the idle air control solenoid, but found the ceramic cracked. Replaced with new, operated correctly.
