There are no long or short flashes, just long or short pauses.
12 - PCM Power loss within 50 last key ons. To be expected since the battery has been out
13 - MAP sensor problem - Controls most fueling, that would certainly be something to look at
22 - Coolant temp too high or low
31 - Problem with canister purge solenoid circuit
Based on your description I get 34
34 - Open/short in speed control vacuum or vent solenoid circuits
55 - End of codes
Almost everyone in the world has a cell phone with video camera. Maybe take a video?
I will wager the MAP sensor is bad.
this tells the PCM how much air is moving thru throttle body by reading "manifold absolute pressure" IIRC.  or mass air flow?
crappy stock electronic junk, strip it for a carb and points dist and never fool with it again.

and check the wires going into the map. we had a Dynasty that was coming up bad map, changed it, stil had the problem. found out one of the wires going into the plug was bad, and when the engine rocked it was sending out a false code.

Several possibilities...good suggestions here, but don't shotgun it! Diagnose it! Start by testing fuel pressure.

There is a maze of spaghetti under the hood and it all is to be related to each other. Make sure your EGR valve is clean and free moving. Any one stupid little thing can throw off fueling. Easy way to tell is disconnect and plug the vacuum to the MAP and see if it still runs the same. Also spray carb or brake cleaner on the hoses and fittings for a leak test. Idle will go up if it sucks any of the cleaner in. I've found throwing parts at a problem without correct diagnosis is throwing good money away. 
with this...I bought an '89 318 TBI Dodge Ram 1500 4X4 brand new...damn thing couldn't get out of it's own way if it wanted to. I was so disgusted with it at the time, I sold it just a few month's later for what I had into it...and bought a '79 360 Dodge 1500 club cab with a CARBURATOR...always ran great!!
