Hey guys - my 2.5 runs pretty badly in the mornings. It hesitates, stumbles and nearly conks out on acceleration until it warms up. After that it's much better, but even when warm it still has pretty uneven power delivery - will pull great through about 2800 RPM then flatten out or slightly lose power before "kicking back in" at around 3200 RPM. I don't know if these issues are related. Right now I'm looking for help troubleshooting the poor cold performance. Thanks!

Hell, I run poorly in the morning, so I can understand your car, lol.

Might be the cold start coolant sensor in the thermostat housing, or the cold start injector not shutting off when it should ie, leaking?
