Hi my name is Chris and my car is doing the same thing your car was doing at part throttle. At 10%-60% part throttle my car is way lean but wot is good. At idle I have a bad Miss that I can hear in the exhaust. I have replaced intake and blower gaskets all vacuum lines and have deleted PCV and EGR. Also car is throwing p0171 and p0174 codes. Did you ever find out what was wrong with your car? Mine is doing the exact same thing. Any help would be much appreciated. Thanks. Please text or call me at 321-693-6274. I am lost on this one. Thanks again
