2018年1月17日 · I have a 2012 5.7L tundra. When really cold it starts really slow. May take 3 or 4 times to start. When it starts it smells funny, smokes and clatters like a diesel. Code is P1604 from O'reileys. No part numbers come up. They gave me about 15 pages of possible problems. Any help is appreciated.
