MIL blinks and/or stays on - Getting P 0302 code (cyl.#2 misfire). Just had car detailed, they "cleaned" engine compartment. Would degreasing/water spray cause this code? If so, will it go away over time?

Yes, the best thing to do is NEVER spray water on an engine unless it's on fire!
Maybe not even then! Best thing to do is dry ignition on # 2 cyl. use a little WD-40.
Pull coil on 2 and do this, inside the plug boot also.
