Background, no issues with car. After a -29 degree day I find the driver side floor board full of water basically frozen. The carpet was frozen and corrosion was in some wires. Not sure where the water came from. It didn't rain and passenger side was dry so it wasn't the ac line? I fixed the wires which was an ignition wire corroded only. Now all of a sudden I get the p2152 code. Car bogs and studders when gas is pressed and barely wants to go.

Seems to be cyl 5 or group c code. Are the cylinder wires also running under the driver side floor board? Any ideas on what this could be? Going to check the cyl wires as I heard this can crack and maybe cause this issue. Once again never had this issue until after the mysterious water flooding the driver side.
