Recall CO2

[JMullens]

Has snyone noticed a drop n fuel mileage after having this recall done. I check my fuel mileage very often by the overhead computer snd it has stayed the same, until I took my truck in and had the recall performed. My fuel mileage has dropped 3-4 mpg and I don't understand why. I am going to actually check it by the trip on the dash this tank and see if it has fallen, or if the overhead computer was affected.

I have been watching that too. The first tank I had quite a few miles on it when they did it and did not think too much about it. I have been watching the overhead on this one and it does seem to be lower,not be much but lower. I will see when I fill it up and put the pencil to it.

What is this recall for?

 

[SOOT]

The recall is to have the ECM reflashed. They say that after using the CC the ECM may set the idle really high and there i no way to bring it back down to normal idle.



It takes less than 30 minutes to do if you don't mess anything up I. E. fallow directions. The ones I have done I have not had any problems with.

My overhead also dropped off about two MPG, but a quicky with the pen and paper still showed about 18. 4. Will do a more accurate figure on this next tank!!

So MMeier, are you saying that your overhead is maybe more accurate now?

I had mine done yesterday and noticed the same thing. I am glad that I reread this post, it had me bothered.

BTW They told me Ihad an air leak in the rear of the truck.

I said "really?" and they said yes. They continued insisting that it was an air leak. I finally told them it was an exhaust brake and left. In retrospect I shouldn't have said anything.

Had mine done and I can see no difference in mileage or overhead disply reading. I have noticed that fuel prices have fallen quite a bit aroud here. $1. 41 is the best I have seen.

mine has also dropped alot, 4mpg, on paper and the overhead.

pulling a lowly 6500# at <70 mph I only got 12. 2 mpg. :--)

last time I made the same trip pulling 5500# I got 16. 7, hard to believe 1000# can make that much difference

Had mine done a few weeks ago, no difference in mpg.
