Hello all! Issue with my 1990 audi 80 non-quattro. cold start in the morning is rough. starts after 4-5 tries. shakes when it starts and then idles pretty good when it gets over its little fit.(like getting a child up for school) once she warms up for a minute or so she runs beautifully the rest of the day. warm starts great most of the time. has new plug, wires, distributor cap and rotor. put some fuel injector cleaner also. cold start valve replaced to no avail. any ideas or suggestions would be greatly appreciated. thanks.....
