When the temp gets cold the truck will cold start and run well until it warms up. Then it chokes down and runs rich at idle, I can see black smoke out of the tailpipe. It is throttle body Fuel injection. It is like it is stuck in a cold start mode and then will not come out once the truck warms up. I at first thought coolant sensor problems but why will the truck run right when the weather is warm?
have the same problem?
