Not all the time but randomly I get a jerk when accelerating. My MPG has been dropping ever since this started a few weeks ago. I was averaging about 22 / 23 city but now I'm averaging about 19 mpg. (2018 / 46,000 miles) If it matters, I buy my gas mostly at Costco. I just got an oil change and was told everything looked good but I needed a new air filter. They didn't have one and thats something I need to go get tomorrow. Any ideas maybe what this could be?
