1990 Trans Am GTA Y84- Currently non running

1990 Pontiac Trans Am GTA

1990 Pontiac firebird trans am gta, y84 code. I have included the options in the center console but it may be blurry. I will add another as soon as i am able.Has a 5.7 non original motor with a holley carb. This has been converted from TPI to carb. I bought the car in the condition it is in now. I am not a mechanic, i attempted to fix the few things i knew how. Spark plugs and wires were where i started. I put in 6 new plugs, it will come with the additional new ones. Has a brand new battery purchased roughly 2 weeks ago (Disconnected when not in use). Has a leather interior. Headliner needs put up, it sags quite a bit. Has a knockoff momo steering wheel and a B&M slap shifter with a different shift knob. The car sounds like it is down on cylinders, could be firing order or compression (like i said i'm not a mechanic) Leaks a little bit of oil, i'm pretty sure it is the oil pan gasket as thats where it looks like it's coming from but i cannot guarantee that.
I know that only 884 gta's were produced in 1990 so this may be rareish (im not entirely sure) I do know i've only seen one other for sale online. Has a 4" Cowl hood, with 3 pinholes. I don't know if the person before me intended to finish it but didn't or if they only wanted 3?
If you have any questions i will do my best to answer them. However like i said i'm not a mechanic.
