I've had this problem every now and then since I bought the car. When shifting into fourth the car will hestitate slightly. It happens about when shifting out of third 4.5k and up. I recently did the snub mount and it helps alot but it still does it. I never was really concerned about it because it's not a huge issue.

I haven't looking into it but it sure as hell seems like a small fuel issue, clogged/dirty filer?

Suggestions?
