Hoping someone may have something. Just swapped the engine in my '07 GT Auto. Idles great, fires right up, however I am getting hesitation around 2500RPM through 1st,2nd and sometimes 3rd. Once it breaks passed, it screams. From a stop to WOT it seems ok, just during normal acceleration. Validated TPS, MAF, Injectors, Coils, and installed brand new plugs and fuel filter. Any thoughts?
