OK so I tried everything you guys told me to try, nothing changed, I cleaned the MAF, code went away.
Still having the weird erratic accelerations and slowing downs. Mechanich told me the Catalitic Converter seems to be blocked. So new catalitic converter or going Decat with another resonator to lower the noise.
Could also create a complete exhaust system Ill see what I do later on.
Now, since I went into deep water and I am 100% sure the exhaust was underwater is there any chance that water could have ran all the way to the cat converter?
What other things could have blocked my cat?
Mechanic says after letting the VX running and not moving, catalityc converter starts glowing red of how hot it gets. I still have to see it in person.
