Efrain ... the truck is the new body style 2007, there is no regulator on the rail. I have had several mornings where is has failed to start w just touching the key to start, just turns over and no start unless I give it some gas ....BUT now it has started every time for the last week ... grrrr.

I did have the engine light come on last weekend for the day but then cleared, don't know the code yet. The garage has been busy and I don't want to press him for using the garage as a favor ... you know.

Suggestions?
