ok yeah its deff the afm for sure. I read up for hours the other night because I just swapped a freshly built re into my 2wd which I bought like 8 months prior with a hole in the block and it had been sitting for a month or so before that. I just new it was clean untill it threw a rod. I proceeded to swap the motor got it in started it up and it runs like a built 454 like fully cammed out all crazy like and i mean it has a cam but no 4cyl cam should run like this did lol. So I started checking all vacuum lines and what not read up like crazy and It all came to the cold start injector or the maf. I mean it was full on black smoke but my cold air intake was whistling hard core like it was getting air.. I just swapped the one for my 4wd in it started it up and like that it was perfect. same symtoms for sure and I tried everything easy to fix it and that ended up being it so I'd say thats your problem and im 99.9 percent sure.
and good call on the bomb proof mounts and motor mounts as well lol. I mean I have polly bushings in my cross member and i still get a good amounts of motor twist with my re lol
yeah i'm leaning towards it being the afm, pretty sure that's it. I'm trying to track down a known working condition one online. Its hard to find them for a decent price. I already have two extra's, but they are a different part number, and they didnt make a difference. I hope its the afm! Just gotta find a good used one cuz i'm not throwin down 400 bucks for a new one
its at my buddies house he offered it to me if i wanted to go to turbo and swap my whole cars to get the luxury stuff too.
its in really good condition!
1990 Turbo Harness 
alright i will think about it and let you know if i want it. well actually i know i want it, but not sure if i want to spend my money on it
