I don't know dodges, except for the Colt Vista that my parents had when I was in elementary school (funny story - it didn't just fail, the transmission actually fell clean off the vehicle onto the road...) so I don't know what kind of systems this one has to watch, but I'd expect your biggest problems to involve carbon build-up. there's a variety of fuel additives you can use for that, depending on whether you're fuel injected, catalytically converted, and a bunch of other stuff that's PROBABLY all going to be standard by '89. Basically, you should go browse the fuel additives section at the local auto parts store with your engine's specs in mind and buy whatever fuel injector cleaners, carbon flushers, or other additives (hell, Idunno, maybe drygas?) you can. If it's at all practical, you'll probably want to change your fuel filter - I've only ever done this on an extremely simple inline filter, and that was easy - because on a car that's passed the legal drinking age, you're likely to find buildup inside the fuel tank that may have been knocked loose.
Also, make sure to park on a clean patch of pavement for the next month and check regularly for leaking stuff. Basically, to be on the safe side, assume for maintenance purposes that this misadventure was the equivalent of driving 10,000 miles cross-country and back, and do any and all upkeep stuff you can.
Also, look up the old ford pinto video. Just to remind you of what can happen if you AREN'T careful. And remember that SAE just stands for 'Society of Automotive Engineers.'
