Engine steam cleaning

[Sicy Stang]

What is the easiest way to steam clean your engine? I have tried using the degreasers, and then rinsing with the hose afterward but the car always runs shitty for a while right after, even had check engine light come on for a bit. I cover up everything that you're supposed to cover while cleaning it. I can never get all the spots clean either. I'm ready to just take it to a detail shop and have someone else do it.. do it right lol.

I decided I'm just going to take it somewhere for $40.

Thanks for your help :p ;)
