When it rains my car loses power while clouds of white smoke pour from the exhaust during which time the car wants to stall and sometimes does. If it stays running until the clouds of white smoke go away the car regains its power temporarily (a couple minutes at best)then the same thing happens again. Worse on any type of incline. The wetter the worse it is. Today for the first time eve rmy car sat out in the cold overnight and although it wasn't raining today the car had no power whatsoever when I went 4 miles to the store. It would only go 20 mph even when I floored it. No smoke though.I recently had the distributor changed out, new plugs, wires but problem is the same. So far intermittent clouds of white smoke only in wet conditions. When any of the above happens the check engine light comes on
