2007 Jeep Grand Cherokee Question: P 0302 code caused by engine cleaning?

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? -
Answer 1
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. -
Answer 2
