Hello,
When I'm coasting along at any speed (usually over 30) on a level surface and give enough throttle just to keep my speed up the engine lags and lurches as if its running out of gas or getting some kind of vapor lock. The tac bounces up and down by 500 rpms. It's as if the engine is going to die. If I give it more gas it accelerates normally. If I just coast with no gas its fine. It's just when I give it just enough gas to keep my speed constant. I haven't taken it in yet and wondered if anyone on this forum might have an idea on what it could be.
Thanks, Luke
