Default Rpm, coolant, fuel injectors, check engine light

Hello folks
So Today the Check Engine Light went on.
I noticed that it had a rough idle the RPMs was high even at cold start, like if i was pressing the gas pedal. Drove the car and noticed it would stay accelerated on its own.
Open the hood to check to see if i could figure out what was going on and noticed that there was some coolant around fuel injectors #5 & #6.
I figure theres a leak somewhere. Maybe a hose,head gasket or even a cracked head

*Any other ideas on what else might be causing these problem(s) Thank You For Your Help/Ideas

Cleaned the coolant out from around the fuel injectors, started the car and no more leaking. I did see that the upper radiator hose has a small leak and I am thinking the fan may have blown the coolant around the engine which is why I thought something was wrong. There is still a rough idle and car still accelerates on it's own.
I have pulled the codes from the check engine light and have gotten PO300, P1313 and P1314.
Any suggestions would be much appreciated.

Check to see if the plug well is full of coolant, had this happen on a Rover once. Caused the coils to short.
