[QUOTE="integritymechanicsbydavid, post: 1567045, member: 38890"] Heard something new today. Cold start and tiny bump bump noise coming from intake box. I’m starting to lean towards a sticky valve. Gonna take the valve covers off Sunday and look at rockers and bridges then do a compression test on all cylinders. While I’m there I’m replacing both injector harnesses. Might as well replace the pressure sensor. I’ll also be adding 60oz Hot shots secret stiction eliminator. [/QUOTE]
