hey guys, so the 87 non turbo i picked up a few weeks ago has this problem..... it will start up first try with no problem what so ever, but then it will idle high(2000-2500 rpm) for like 4 seconds, then start to drop. if i let it go, it will stall, if i dont let it go and flutter the gas when it wants it, it does fine, but starts smoking a clearish/ bluish/ sometimes puffs intermitantly of black smoke. and as soon as it stalls or i turn it off, it wont restart, no matter what. i have to wait atleast -6 hours before trying it again, and then it will start right up first try to hard starting. any help would be appreciated. i have been busy working on getting my other car back together, so i havent had time for this problem. any clues or guesses would help me jump right to things when i do find time. thanks you guys.
