Angry help 84 FB 13b misfiring cant find problem!

Ok so my 13b fuel injected 84 FB has been misfiring for about 2 months now and I thought it was a spark issue because the wire going to my coil pack was arching but i fixed that and nothing happened, but then I was out driving and after I ate at a restaraunt I turned it on to drive out it was misfiring like crazy and unless I was pushing the gas pedal constantly at a stop it would just die on me, at the moment its having trouble starting and when i get it to itll die again and then the spark plugs are covered in gas, after troubleshooting I believe its the fuel injectors or I saw a diagram of the set up and saw the pressure regulator and Im thinking it might be that to but Im unsure. Someone please give me som advice Ive been out of my FB for 2 weeks now and its killing me I want it fixed ASAP

I doubt it's the pressure reg. If the guts of it go out it can starve the engine of fuel but one that is just failing to bleed off pressures at idle shouldn't cause such severe problems. Since I haven't owned a 1st gen, sorry I can't be much help. But maybe a bump will help you get some responses.

well the way its happening is like at idle its idling really low like even the sound of it is much more low toned and I think its getting to much gas because it keeps soaking the spark plugs so idk my next best guess is the injectors but again im unsure
