1991 Acura Legend White smoke

Hey guys, I have a bit of a problem here. About 2 weeks ago I got in a small fender bender in which a woman backed into the front of my vehicle. Now, it wasn't a very powerful impact, and the only visual damage caused was on the bumper and the left front fender above the wheel well. Now, two weeks later, I was confident enough to strap up my bumper and take to the road to make sure it was running fine. However, while on the road I stated to smeel a distinct (burning) smell and when I got back to the ouse and left it idling, realized the amount of white smoke coming from the tailpipe. The smoke was constant as well. Also, the further I push down on the gas, the more smoke comes out. Now, I had left it in the garage sitting for two weeks, in which were pretty cold and damp. I thought such moisture build-up could have caused the problem, but now i'm thinking more and more that this is an unlikely cause. Any help would be appreciated. Thanks.
