very rough running any help appreciated

so i purchased a 84 that hasnt ran in over 3 years. i got the car running by squirting gas in the tb, running enough to get it on and off the trailor. well i finally got a new fuel pump and tank, enought to start the car. so i started it up today ( first time ever) and i had to keep playing with the tb to keep it running and if i kept the tb in one spot it would stall. after a min the car seemed to warm up enough to where it would stay running but if i softly played w the tb it would stall right out. i noticed there is a exhaust leak but i dont think that has anything to do with anything. any help on where to start. also i knwo my check engine light works cause with the key on but car off the light comes on, when i had the car running for the min / min 1/2 i had no check engine light. but when it died with the key on the light came back on?

i did some more searching on here and i unpluged the MAF. the check engine light poped on but the car ran so much smoother. so im guessing that is the first thing i should change. also it is my up pipe that is leaking from the center of it. does anyone have a stock up pipe and MAF they are looking to sell?

First...do the spring cleaning on GNTTYPE.org link: The Grand National / T-Type / Turbo Regal Buick Spring Cleaning Guide

If air is entering the car after the MAF it may cause the car to run rough. Is there a way that you can (Just for the time being) patch the hole in the uppipe to see if the car runs well with the MAF plugged in?

If you are not looking for a pretty uppipe I have one for sale. I can send you a PIC. The 84/85 MAF's are really rare. The remanufactured ones are hit or miss. You may have to ugrade to the 86/87 ECM, MAF, IGN and module. The 86/87 MAF are out of production and the remans are iffy as well. Alot of people use a translator and a new GM MAF from Impala SS.
