You do realize what the mileage is when you warm the car up? 0,zero. How does that improve mileage? Also,are you going just by the computer? What about at fill ups? How long do you warm up the car? The only reason to warm up the car is for your COMFORT.Yup I had to get a clicking noise fixed from the tailgate when it was brand new.. they said they couldn’t hear it the first two time I went.
do you warm up your car? I do and the dealer told me not to.. so that I get higher mpg
when you are slowing down at a stop sign hear carefully and see if there is a hard rough clunk at 15 miles. Istarted getting this when I follower the dealers advise of not warning up the car last winter. Even after reprogramming the transmission it is still there. Not a good buy
