Bought a 1987 E30 Vert early last month. Been having some cold start issues that I cant seem to resolve. If the car sits for a day or two it starts fine, goes into a high idle (1000 rpm) and stays there until warm, then kinda bogs down t0 500 and stays there, runs fine after that. Now the problem happens when its been ran that day, but cools all the way down. Then sometimes it'll start then die or i have to give it gas for a couple seconds (10-15) then feather down the amount of gas I'm giving it till 500 and it'll stay there.
I've changed out plugs, cap, rotor, timing belt, adjusted valves, changed the oil/ filter, flushed the coolant, has a strong battery, new airfilter. I've also checked and cleaned the MAF type thing and checked all vacuum lines for cracks.
Once she warms up she runs fine with the exception of an occasional high idle when I come come to a stop, which usually reduces to normal after 10 seconds.
