Default HELP! Complete Engine Hesitation And Sputtering Under Any Load

So this problem seems to not want to go away, started yesterday. I start accelerating and releasing the clutch right and it sputters, the engine. I manage to get into gear but any time I press the petal down more than 1/4 it sputters and hesitates, puts out very little power.
Yesterday I got an oil change from a place (tried to do my own but the bastards who did my oil last impacted my oil drain nut on), they over filled it by about a quart because they looked my engine up as a ******* V6. I did a SeaFoam yesterday. All of this did not seem to effect my engine.
But I washed my engine bay yesterday-- Purple Powered everything. I was somewhat careful as to what I washed and didnt but not to the extreme or anything.... Its been a day now and everything seems dry in there. My ECU box never got wet, its bone dry inside.. Is there anything I might have gotten wet that would cause this???

CODES:
P0300 Random Multiple Misfire
P0302, P0303, P0304 Cyl Misfire 2, 3, 4
P1250 Manf Cont Fuel Air Metering

Some of this was probably from the SeaFoam the day prior though..

But UPDATE: Now when I drive its so much worse. Constant misfire sputtering or whatever it is and a blinking CEL

no cel does not mean no codes.

troubleshot. i found that some water had gotten under the coil packs and into the tunneled area where the spark plugs lie. what caused the sporadic misfiring was the water grounding out the positive post feed on the spark plug.
science!
anyways.. i took lots of pictures and if this seems to be a common occurrence which i can assume is possible i will be posting a write-up on how to solve this little problem without simply unscrewing the spark plugs releasing all that water into the combustion chambers. theres no gasket or tight seal on those coil packs.. just another one of the little things some 'german engineering' would have been useful on.

Did you spray water on your engine? I don't see how water could get onto the coil packs if you had the engine cover on. And with the double firewall, rain should not be be going anywhere near the coil packs.

the first time i washed the engine i had to to a major cleaning and i got water under the packs too. they have a tiny little o ring around the edge but in order for that to be water tight it has to be exactly flush with the valve cover, and all of mine had alot of road grime in them and one o ring was broken in several places.

to solve the problem you dont have to remove the spark plugs all you do is take the coil packs off and blow out around the plugs with some shop air. after that i went back and sprayed some 93% rubbing alcohol down there to mix with the remaining water then hit it with some air again. leave it sit for 5 minuits while you go dry the coils and all the alcohol will evaporate with the water. good to go. this also gets rid of any dirt that falls in around the spark plug hole that is almost impossible to get out without pushing it into the combustion chamber.
