Any trouble driving? Stuttering, stalling, pinging, poor gas mileage, poor acceleration? Thats pretty vauge.....if we are to help you we need a little more info. Otherwise a trip to a reputable shop is in order.
If you're feeling good and would like to learn a little about your truck-let us help and give you some background info so you don't throw away you're money at a Stealership or backstabbing shop-reputable may be hard to come by-or otherwise impossible.
At least give some of the info listed above and maybe we can walk you thorugh a diagnostic-so when you do take it in (if you want to) you know what to ask for and what to refuse.
Usually these "lights" are minor. First thing is first though-check your owners manual for the 'EFI fuse" -find it and with the engine off take the fuse out for about 10 seconds. Replace it and then re-start the truck-if the light comes back on it is a definite maintenance indicator-if it doesn't it could have been a blip for some reason.
I asked the same thing a while back.... here is a thread with some good information... Welcome to the forum... there is a search feature on it that will help you find information on almost any help you need... most of it is good stuff...
