I've been getting a Check Engine Soon light recently and the code says a missfire on cylinder 1. Replaced all spark plugs plus relplaced the coil on cylinder 1 and cleared the code. The light keeps coming on but the car doesn't feel like it's missfiring and garage can't figure it out. Any help please?

For a single cylinder there are not many other choices. A bad injector will do the trick. It is less likely you have a bad valve or seat, but always possible.
