I bought a focus before I started watching your channel.  Otherwise I would known better.  It's a 2015 ford focus with 95 thousand miles on it.They reprogrammed my computer to fix my transmission problems. It seemed to fix it. No jerky transmission. Recently, I was going down the highway and I floored the gas to get around someone. It flashed an engine fault warning and it started slowing down. I managed to get to the side of the road. The car would go forward but at a snail's pace. It seemed to be barely putting out any power and the engine didn't sound right.I had to get it towed. What are the possible things that could be wrong with it? I still owe a lot of money on it and I feel certain I'm going to pay a fortune to get it fixed. Please help.
