Steve,

Thanks for getting back to me so promptly.
The shutter occurs while passing through the aformentioned rpm (approximatelly 1300-1500)
Depending on how I'm driving I can almost miss feeling it.
It's most noticable going up the rpm range, off idle. I don't detect it on decelleration.
What is the EOIO 20 step enrichment test and where can i find the proceedure.


Thanks,

Knarf
