I have recenlty noticed my truck will white smoke when in drive and not moving. It starts to do this after about 10 or 15 seconds (like sitting at a stop light) it does not smoke when started or when left to idle in park or neutral. I used a bottle of injector cleaner and it seemed to lessen the smoke but not cure it. Im really pissed because I just bought the truck 2 months ago and it started this in the last couple weeks. 142K miles any suggestions would be great
