I hit a big flooded area wit my civ and ever since it wont turn over all the time but its basically at the point of turning over. And when it does turn over it idles fine and gives gas fine. But once u start driving it, it dogs out and will just cut off on me and wont start for a while. No clue whts goin on with it

 

Drain and replace the oil if anything. Also, maybe a sensor became damaged in the flooding. Any check engine lights?

 

Did water go into the air intake? That can cause internal engine damage.

Check for water inside the distributor (if equipped, you didn't say what year you have). Leave the cap off and dry it out. Pull the spark plug wires (or coils) out and check for water in the spark plug holes. Cvcrcr has a very good point that you may have water in the oil and in the transmission.

 

Its a 99ex. And yea my check engine lights on. I need a crankshaft position sensor, idle air control valve, knock sensor, and throttle position sensor. Was gonna get all this next week but then this happened.
