We’ve heard from a lot of people that the second generation Tundra can be hard to start in cold weather.
TTC member reports after taking his Tundra to the dealer, “They were able to fix the issue and gave me loaner while they worked on it. The issue had to do with the sensors that detect the alcohol level in the fuel. I was told the sensors had to be recalibrated. If I remember correctly the sensors were estimating the alcohol level in the fuel at 50% and was trying desperately to compensate for that mix and could not do so…hence the extra exhaust. I was in reality not using E85 gasoline at all. Since the recalibration it ran just fine all winter and for the last year. Twin City Toyota in Festus, Missouri took great care of me, and I couldn’t be more pleased. Hopefully it doesn’t fall out of calibration again though. I have decided not to take any chances and I won’t be using any E85 in the truck, or at least that is our plan.”
