84 190e cold start problem+very rough idle
 

Hi,new member,great website!
just bought 190e 1984, 220ooo miles, rough shape
im in montreal, its about 3 degrees f, car cranks well
but just gives muffled atempts at starting,i can start it with cold start fluid
once it starts it runs very rough and stalls at any atempt to give it gas for
first 5 minutes or so,its idle smooths out as it warms up, after 5 mins i can drive away
and car runs ,accelerates well. hot or cold it always idles rough,no problem restarting it if
engine is still warm, ie one or two hours. ive changed cap,rotor plugs,wires,run some ingector cleaner through gas, and sprayed cleaner trough throttle body,
any suggestions what to do next? any help woul be greatly appreceated.

look behind the battery on the passenger side of the firewall behind the battery is a plastic cover remove this and you will see a few computers bundles of wire and a large relay there is a plastic cover with the hinge facing the front of the vehicle pull this cover up and the is a 10 amp fuse under it pull this fuse out with a small pair of needlenose pliers and replace it
