I'll pull my timing belt covers off to see if the belt flaps. I'm not sure if its possible to see, but I'm not sure how else to check it. Any suggestions?
I've noticed that my miss is most pronounced at ~ 2700 rpm and it'll miss constantly at this point, whether I punch it in neutral or if I'm at cruise. I've also noticed that @ if I'm accelerating slowly through the 2600-2900 rpm range, I get an occasional sustained 4-5 counts of knock until I let off the throttle. Maybe its some sort of resonant frequency of the slapping belt causing the CAS to misread? Dunno, this issue has me baffled.
