New Clutch No Power now at Random

[Mr Hagg]

Sounds like the speed sensor plug may not be getting a good connection... and ecm is switching to NON VSG mode... you can open insite and max that out see if it helps....at the bottom you'll see non vgs setting and most of the time its set to 1400..Only reason I say that is cause you said it want hold cruise.... The other thing I was thinking was maybe they took fuel lines off and now they are sucking air....
