Ok guys, sorry to bore you with another jetting question, but I have read, watched, searched and listened to helpful friends and I am still no further ahead. I am still unable to eliminate the hesitation in my motor off idle when I hit the throttle (bogging bit*h). The car does pull very strong from mid to top end, but since this is only a street car, the response is very important to me. I have also notice that when I bring the car in from a cruise and the car is around 180 to 190 it seams to idle a little bit higher recently (1000 to 1100RPM). This may be due to the colder weather / better fall air and a possible lean condition?* I did check all of my vacuum ports for leaks and came up empty. Once the car cools down, it will idle back down to 850 RPM.
