Hello all,

Very funny!!!:lol: I should have added, this is after a few trips to the gas station, and checking the cap. it's not a loose gas cap! thanks for the reply though

sensor error is sounds like, does your fuel system read right i.e. mpg in dic working ok, level of fuel seems right, range working etc.

yea i had nothing, and when you have nothing the smarta$$ tends to come out....:thumbsup:

Yeah all that is working fine and seems to be accurate(Fuel consumption, range etc.)

An update for my Gas Cap/SES issue: The truck seemed to running OK with the SES light on earlier today, so my wife tried to drive it tonight with the SES light on (she only had a few KM's to go, so decided to chance it). After a few minutes the SES light started flashing, and it would barely run, so she had to turn around and go home-she called me at work with a few choice words about my new baby( she basically does not trust this truck yet, since this the second time this has happened to her). I hope the dealer can fix this, so she trusts my baby again!!

I don't know what that could be. I was driving my brother's F-150 the other night just to run down to Lowes and it did the same thing. The gas and SES lights came on and it felt like it went into reduced power mode. Then I restarted it, it ran normal, but the lights stayed on. By the time I got home everything was back to normal. Wierd. Sounds like it may be the same thing, but it hasn't happened to him before or since.
