Is my car save-able? 2002 ford focus?

My car went through a great deal of water that was up to the body of the car. I know water got through the exhaust pipe and the engine sucked up water. My car can still turn on but it stalls when stopped or idle. It sounds like a Diesel engine when ran. My dad took out the spark plugs and there was water in them. I took paper towel and q-tips with pliers and got a good amount of the water out but it's still not dry after 6 hours. When dry is it still worth repairing?

Buy it

If it went swimming in fresh water you might save it… If it was salt water, then corrosion is likely throughout the car, brakes, bodywork etc, etc, etc. I'd part company with it and look forward to a joyous new replacement.

REMOVE THE PLUGS and spin engine OVER with VACANT PLUG HOPI: LES! All water will be DISPELLED! It is NOT from the EXHAUST but from your AIR INTAKE that gets water into things! AFTER YOU SPIN OUT the WATER< the engine will start with the pugs put BACK IN THERE! IF IT DOES NOT< you have BENT RODS, maybe! SORRY PAL! LEt ENGINE PUMP OUT WATER through plug holes first! Clean the plugs and re=-install them or use NEW DENO|SO or BOSCH iridium pugs! BYE NOW!
