IVE STILL GOT A CUSTOMERS HYSTER IN THE SHOP THROWING A 522660-0 (RICH FUEL READINGS)
HYSTER H50FT (6278 HRS) 2.2 MAZDA. IMPCO SERIES 3 REGULATOR. O2 SENSORS WERE REPLACED ON THE UNIT A FEW MONTHS PRIOR. I REALLY DONT SEE THIS BEING AN 02 SENSOR PROBLEM. THE CATALYTIC CONVERTER HAS NOT BEEN REPLACED ITS FACTORY. PLUGS ARE NEW AND GAPPED TO SPEC. NO EXHAUST LEAKS, OR INTAKE LEAKS.
THOUGHT ID RUN IT BY A FEW MECHANICS IN THE FIELD BEFORE WE ORDER A PRICEY CAT. THANKS SO MUCH FOR ANY HELP.
