Hey guys, i'm stumped.. I've searched and searched, but cant find anything that matches my symptoms. Lately my truck will lung while light acceleration, the RPM will drop off then jump back up again, like I keep tapping on the throttle. The RPMs will vary about 300-400 RMPs. Now it doesn't do this all the time, its hit or miss, but usually more off then on. If I am under mild or heavy acceleration it shifts great and there is no problem. Truck has intake exhaust and BDP chip, truck will do this no matter what tune it is on. If there is any questions or if anyone can give me some insight, it would be greatly appreciated. Thank you.
