Did you replace the distributor with a new OEM unit, or an aftermarket one? The quality of many aftermarket distributors is less than acceptable. Code #15 indicates a problem in the distributor-check all wires in the distributor carefully and check the wiring between the ECU and the distributor. Did you plug in both connectors to the distributor? If the distributor is good, the problem is probably something simple. Nine times out of ten, these kinds of problems are something that we have overlooked. It happens to the best of us.
