csi = cold start injector. It sprays some extra fuel in the intake manifold when the engine is cold. There is a switch for it that is set by coolant temp. It is on the top of the thrmostat housing. IIRC the pre89s are brown while post89s are grey. The injector itself is on the bottom of the intake plenium between runners 3 and 4. Check both the switch and injector.
