I have a 2008 Ford Fusion with 125,000 miles, and I'm having acceleration issues when my car tries to take off it hesitates and then jerks. I've had so many things done on this car and I still can't find the problem. I was told that the reason why my car was doing this is because I needed a transmission and coolent flush, I got the transmission flushed but not the coolent. I was then told I need a valve cover gasket, I got that and nothing has changed. I went to auto zone to use their code reader and the guy didn't find a code but he stated that I may need new ignition coils , that's why my car hesitates and jerk after acceleration. But back in January my car had bad gas in it and it wouldn't start, I got it towed to a local shop and the guy told me that I had alcohol in my gas also I had water mixed in my oil. He cleaned up everything and he told me that he changed the spark plugs and all which ranned a total of $560. After I got my car back the check engine light was on and I took it too auto zone and one guy got a "P Code" stating that it was my throttle body assembly.
I don't know what else too do & I don't want to keep paying hundreds of dollars out.
