I bought this truck with a misfire thinking I would get around to fixing it and keeping it however I don't have the time like I thought I would. I haven't had a chance to finish diagnosing the misfire so my guess is as good as yours, literally hauled it home and haven't messed with it other than to move it around a few times.  It has 205,000 and drives down the road just fine.  I haven't owned it very long so I don't know a whole lot about it.  It does have EFI live tunes and a fass fuel pump on it as well.  It also has rear airbags with an onboard compresor.  I have a clean and clear title in my hand for it. Front tires are probably 90% tread and rear tires are about 40% tread.  It is being sold as is with no guarantees.
