My 2011 Roadster is popping back through throttle body and hesitating at 2000 to 3000 rpm. Since replacing MAP sensor and vacuum lines. Symptoms were similar but much worse when the sensor sent a code. I replaced it but it's not back to 100 percent. Any ideas what else.? Coil connections are fine, it has a PC5 with AT and Ram Air filter, and Paul Bryant slip on.

Hard to tell from the wording, sounds like a separate incident he is comparing it to.
