Hi Scotty I've got a problem, my car was running fine on the way down on a road trip and seemed fine on the way back but it fid take more gas to get home. The next day upon starting it, the car started shuttering, it does it in park when i accelerate or when i start driving mainly at lower speeds, it still has decent acceleration but gas milave sucks. I did a tune up in the summer last year. Any help please

have it scanned and pay attention to map sensor data, it could be bad or need cleaning
