1997 Suzuki Sidekick problem with my side kick!

Friday, I go on the ice with my sidekick but the ice broke and the back of my sidekick fall into the water! The engine doesnt go into the water! It's take 3 truck and 6hours to take it out but at the hour #4 when I want to start it, It doesnt work! When it's finally work, the truck was bucking a lot and it's continue to buck now! When cold and On neutral the truck is not to bad but when it's hot it's bucking a lot and if I try to put it on drive there's no power because it's bucking to much! I try to fix the problem many ways!
-I drain all the old gas and put some new with Gas line product to remove the rest off water if there some!
-I change the gas filter
-I change the spark plug
-I verified the coil
-I clean the injector and verified if they work well
-I take the compression
-I check the code with the OBD2

Does somebody have an idea for what can be the problem?

Thanks
