like scott says it is ok then goes into closed loop where all the sensors are working . where are you located i have a scanner i might be able to hook it up and scan through the paremetors and see if anybody lnows what is off for readings f no codes come up not sure on obd1 but i know obd II throws a code for o2 sensors

you either need a good digital multi-meter or a scan tool and start looking around. i was borrowing an isuzu trooper about 10 years ago that had a 2.8 gm engine in it. i had to replace the o2 sensor and just got one from pep boys. about a month later the c.e.l. came on and it had an o2 code in it. the voltage from the sensor was stuck around .300v which indicated lean, so i sprayed some carb cleaner in the throttle to richen it up and the sensor didn't move. so i bought a gm sensor and problem solved. as someone else stated what sensores did you use?
