Last night, we had a huge thunderstorm towards the evening in NY and flooded a couple of streets. I drove through one of these streets with my coupe, the water was probably 3~4" deep. As I was driving through, I was so scared the water was going to come rushing in through the doors. From what I saw, I suspect the water level didn't reach my front license plate. I checked the bottom and it seemed ok. I am wondering if what I did will cause any problems to the car?

I drove it afterwards that night and the next day and it started up fine and everything. Although the next day, the car did seem a bit "sticky" accelerating, or am I just bugging myself out? Any thoughts or experience in this? Thanks.

 

You should be fine if the water only got as high as you said it did... which should be below the level of your intake. If it was above your intake box, you'd know it by know, because the car would probably have a hydrolocked motor.

Usually with deep water, aside from ingesting water into the intake, the main concerns are that you might have submerged the alternator, which can lead to premature bearing wear in that component, and that you may have submerged the differential in the water and ingested water into the differential through the breather hose. Water in the differential would be a huge problem... and our cars are pretty low, so you might want to consider changing your differential fluid ASAP in case there is water in there now. I haven't really ever paid close enough attention while under my car to see the height of the area where the breather hose on our cars routes to, so I can't say for sure if it's higher off the ground than the top of the licence plate or not, but I did look up its location in the FSM, and it appears to be right at about the point where the driveshaft and joints connect to the differential. Still... without seeing it in person, I can't say for sure if it's above the level of the license plate or not... better change it to be safe though.

 

I know the feeling.... (My G weathered a storm we had a few years ago...)
