When I start my '01 f-450 on a cold morning it starts easy but has started smoking really bad blue , rich smoke and tries to miss a little but not all the time. After the engine warms to operating tempature the smoke quits with no miss and runs great. Power, fuel milage and everything else is normal.
I only have 72,000 miles on this truck.
The dealer ran a check and told me that all 8 injectors were bad. I have a hard time believing this because it runs too well when warm. And the chances of all 8 going at the same time is rare.
I changed the engine tempature sensor before going to the dealer with no result.
All the other sensors checked fine at the dealer.
Anyone have any suggestions????
