Message	I wasn't able to find exactly what I was looking for using the search feature, so I figured I would start a new thread to see if someone can help me figure something out. On a cold start, I have hesitation below ~2500 rpm. Above that engine speed, it revs up and runs normally. If a shift drops me back below 2500 rpm, the hesitation returns until I exceed that engine speed again. Once everything is up to temp, the car runs normally at all rpms. Plugs are good, no codes. If someone could point me in the right direction or has had a similar experience, please help me out. Thanks.
