yesterday i was driving back home and drove down a hill and never even got it out of first... i just coasted in 1st gear and only let the rpms climb to about 2300 as the hill was VERY steep and bumped up the rpms just becuse of the hill... about 30 seconds later when i was at the bottom of the hill i can smell something, and it appears to be white smoke... now would this have caused my car to smoke when it doesnt ever smoke otherwise?? or is it just coincidence and it was the old volkswagon behind me that was smoking?
