    I've already searched for "surge" and didn't find anything. 2006 GT 3.8 Supercharged. New plugs, wires, vacuum hoses and cat. Just mentioning those so no one goes down a rabbit hole, as it was doing this before I changed them. Ok - engine runs great, nice and strong on boost, however, at part throttle (say motoring along on a flattish road at 30-45 MPH) if I start going up a hill or give the throttle a gentle nudge to accelerate a bit the engine starts to "surge". If I mat the gas pedal it's spot on (pulls like a beast). Ideas? It starts easily, runs great, is giving me 24+ MPG (my calculation, not the cars) combined. No codes (and the CEL does work). Thanks in advance.

    Yeah, sounds like tcc. Tap your brakes then throttle out.
