"Dont directly spray any wiring, electrical connectors, throttle body, or PCM"
is that enough to ensure nothing is going to be damaged
what if water got down a dipstick somehow
i guess our cars all get wet at some time, rain,snow,car wash but its not like it soaks/drenches under the hood in any of these circumstances i always thought of an engine shampoo at shops a sketchy thing to pay for/have done.. unless you drive a viper or corvette, even a camero/mustang then maybe it would be worth it..
im just to scared to risk it haha thats just me
if someone could make me more confident, i am all ears
