My build works consistently except for idle after running 70MPH for a while. Not 65, but 70MPH. She doesn't want to idle afterward for 15 seconds or so and then she's back. Engine temps are under 220 degrees @ 95 degrees F ambient or less (two up) for extended runs (oil cooler), and there's power to spare under all conditions. Even in the mountains she runs good. Even on Ethonol she runs good. Even on 87 octane she doesn't fart, and, runs good. I'm wondering.............I've tried bumping the PC idle fuel/[email protected] zeroTP-experimented a lot. Not much if any difference. Anybody want a shot at why she lowers idle after roaming @ 70MPH for a while?
