Hook timing light to the spark plug cable closest to the belts on driver side (#1). [90% sure since that's how it is on my d16y8].

Also,
check for vacuum leaks using carb cleaner/brake cleaner.
check MAP sensor - some1 can probably take a couple of pics from Helms manual for you on this...
coolant level
warm engine up before driving

In any case, depending on how long it has been running rich, your O2 sensor and your cat are probably fried. Probably worth it to replace those after you figure out why it is running rich.
