[QUOTE="HDSlowride, post: 432349, member: 19912"] Well, I did have time to change out the coolant sensor. The old one that I took out did check correctly in the ohm range at room temperature (12.8K) although I did not bother to put it in hot water to see if the resistance changed as it should. I just put a new one in. I also replaced the rubber elbow on the vacuum line from the fuel regulator to the throttle body because someone had wrapped some tape around it for some reason. Anyway, did those two things and the engine miss after it warms up is still there. Runs good...until it doesn't! I did try one thing....after it warmed up good and started cutting out, I just turned the key off rolling slowly down the road. Left the engine off for maybe five seconds or so and then turned the key back off and popped the clutch to bump start it back off. It seemed as if it ran fine for a couple minutes before it started missing again. So that is something odd that I'll have to work out in the diagnosis. Well...that will be about all on this thread until I return from a month long trip and get back to work on it in December. Again...if y'all think of anything that might help, drop a line here. I'll check in when I can and hoping someone will eventually say, "oh yeah, I know just what that is"! [/QUOTE]
