2003 Mazda Tribute ES Sport Utility 4-Door 3.0L

Up for sale is a a 2003 Mazda Tribute. I purchase it from my uncle in Dec. before he passed away. I have been trying to figure out what is wrong with it since and I am now done with this vehicle. For someone who understands what is going on this would make a nice car. I will describe the Mazda as truthfully and accurate as possible. The Mazda-- Automatic; AC; Leather seats ;Sun roof; 3. 0 V6; 4X4; heated mirrors Tires are at 75%; CD/Cassette player; Heated driver's Seat Inspected through 6/15 in State of Virginia What is wrong -- It is continually getting check engine codes of a Misfire at 1000rpm and Misfire at #2 I have had all of the following replaced. it helps the problem for maybe 5miles. So I turn around and stick back in the garage. It idles rough and loops between 500 and 700rpms. Shutter and stumbles when under load or accelerating. it is at this point the check engine light comes back on. I would not recommend driving it far as it may damage the car further. When I do I only go about 5 miles at low speeds I have replaced in the past month the following - all six coil packs - all six spark plugs - valve covers - intake manifold gasket - EGR Valve - DFPE Valve - Mass Air Sensor - Idler Air control Valve - Throttle Position Sensor - Cam Shaft Position Sensor - Crank Shaft Position Sensor - Air Filter - a few bad vacuum lines that is almost a $1000 IN NEW PARTS Besides the above list issue. that is all I know mechanically what it is doing. As for looks below is the description: - Paint is gone from roof around Sun Roof. It is not leaking - Hood is Dented a lot from Deer strike. missing the Silver trim - Interior is in great shape. no tears in Leather. no Cracks in Dash PLEASE NOTE -- The title. because of the way My uncle filled it out reads mileage as 90280. but the Mazda itself has currently 87891. I was not expecting to get rid of it this quick. so i did not have it corrected when I registered it. I am asking $2200. 00 or best offer for this Mazda. That is more than half what all the websites such as KBB list it as.
