"I have a GMC 8v92 eingine installed in a seiner with approx 2500 hrs. on it. The engine has recently developed a problem whereby it stalls when the throttle is retarded to idle (approx idle is 600rpm). The stall can be prevented by very slowly retarding the throttle to idle, too slow to be practical. Microcommander controls are installed. I have changed fuel filters and cleaned the Airsep filter with no affect on the problem. Any ideas before hiring a mechanic to troubleshoot?"
