Timing and Metering Valves

[TerryB]

Yeah there's a lot going on here. My CM570 has a rough idle when cold, and every now and again when warm. But not at any other speed other than idle. It's runs rough, stutters, misses or whatever else you want to call it. It's easy to believe it could be any one of these components causing the problem. No warning lights, haven't had Insite hooked up yet.
