    1999 175/EFI Timing Specs

    OG947018, Service manual only lists timing specs for a 175 XRI, should I assume it's the same for for a std. 175 ?

    Use the 175xri designation for specifications.

    If you've removed the idle stabilizer/advance module, and index all six cylinders, you may be able to utilize slightly higher timing (not sure what all you've done on it).
