'92 Dodge Stealth R/T Twin Turbo 19,800 original miles barn find NO Reserve!

1992 Dodge Stealth R/T Twin Turbo with less than 20,000 original miles Hello All, recently acquired this car from a neighbor. I am thesecond owner now of the car and pulled it out of climate controlled storage where it has been sitting untouched since 2009. By looking at the Carfax it looks like most of the 19,7** miles where put on in the first two years and after that not driven much at all. The car was hard for theoriginal owner to get into so after a couple years started driving something else. The car wasoriginally from Seattle Washington and around 2008 was brought to California. Overall a car in great condition but not mint. There are some dings and dents fromsittingaround all these years. The interior is in excellent condition with just a little wear on the driver's sidebolster from getting in and out. When i went to pull the car out of storage ibrought a battery up and to myamazement it fired right up. Itwasn't running great due to old gas but drove it into the trailer. When i got it home i drained the fuel tank, hange the oil, il filter and fuel filter. It seemed to run fine whenidling but much over 2k RPMs it would run ruff. After talking to some experts theyadvised that it was most likely the ECU so I bought a Chrome ECU that converts it to OBDII and allows you to plug itinto a computer. That seemed to make it run much better and seemed to run perfect for a couple trips around town and then all the sudden it started stumbling randomly above 3k rpm. If youdrive itmodestly it runs fine but when pushed into the higher RPMs it will stumble but only when its warmed up. Ican't figure it out andhonestly think it is something simple but i have put off other projects and have given up a spot in my garage to store the car. Ididn't want to sell the car not 100% done but i need to let it go. Current pink slip in hand. Currently non-oped in California. Comes with original bill of sale, indow sticker, nd tons of paperwork. We will work with buyer to arrange transportation.
