My check engine light keeps coming on. I have had it to the dealer 5 times. Each code is PO305, injector #5. They have Switched coil wires around, changed plugs, changed fuel injector and most recently used a engine cleaner, thinking carbon has built up on the valves and the light still comes on.

Do you
have the same problem?

No
