Has anyone else experienced the RPMs hanging in between shifts on their GT350? Sometimes when I press the clutch in and shift to the next gear, the RPMs actually increase a little/hang rather than dropping. I have to hold the clutch in for 1-2 seconds for the RPMs to stop "sticking" and begin to drop again. This happens without any error messages or warning lights and it is intermittent, but it seems to be getting worse after my resonator delete (issue did exist prior to res delete). The car is 100% stock other than the resonator delete. If you have experienced this before, let me know what fixed it. Thanks!
