I have a buddy who thinks my cam has at least one lobe problem. I put a vacuum gauge on and it gave a super steady reading of 20, right in the middle of the "good" range. I blipped the throttle solidly and the gauge went down to approximately 3 or so, then rose back to around 25 and settled back to 20. Engine fully warmed up. Possible to have a cam lobe issue and get these results?
