Issue or not? - ZR-1 Net Registry Forums

No codes stored. Pulled plugs and they look decent but I was replacing them anyway. I did notice the vacuum pump runs then shuts off, but does cycle for a second every 10-15 sec. I hood up my mity vac and pulled a vacuum on the line going under the plenum. It falls pretty quick once I pull it down to 25". Are the actuators suppose to hold the vacuum, or guess I'll be pulling the upper plenum.

I do realize these are an upper rpm motor, but I really expect to be pulled into the seat up top and really don't feel that.
