2002 Mustang V6 3.8l Rough Throttle From Idle

So awhile ago I had the car washed at some gas station car wash and soon after the car ran horrible no matter what. It shook at idle and it hesitated a ton when ever I gave it some gas. Took it to my mechanic and he said it was the fuel injectors so he had them cleaned. Never did say though if it was because moisture got into the injector or anything like that (from the car wash).

So about a week later, it is still giving me problems just not as bad. Now it is whenever I start the car on a hill or try giving it heavy throttle from an idle or throttling on a hill. I ignore it for a little and then I took the car to get it washed three days ago and right after it seemed to get worse. Just two days ago after getting off the freeway it threw up a cylinder two misfire code (P0302). But then weirdly enough, the code went away yesterday but the problems still somewhat persist.

Not sure if it's something with the fuel injectors or what but some help would be amazing, thanks a ton!
