Ermmm...cold start injector maybe?
About the ECU codes and timing:
You can get the ECU to give error codes by putting a wire (shortcircuit) in the yellow connector with rubber cap that dangles on the firewall somewhere around the intake manifold. Late model ae86's have a diagnosis box where you need to short 2 terminals or something.
Anyway, when you do this, the ECU gives you error codes through the
orange check engine light in your dash. It makes patterns of flashes (you need to count how many flashes it puts out), the description of the codes is in the manual. Also make sure that your timing was checked when the diagnosis connector was bridged, because it stops the ECU dynamically changing the timing (which is the only way you can set the timing properly).
