Engine Performance problem
2000 Chevy S-10 4 cyl Two Wheel Drive Automatic 50000 miles
My Chevrolet S10 is burning more fuel now. My OBDII scanner gives the following readings for the oxygen sensors:
O2 B1 S1 shows fluctuations from.1 to.7mv
O2 B1 S2 shows a constant.7mv
This is in Closed Loop after warm up.
The O2 and CAT monitors show that they have not completed their monitoring.
I appreciate your help.
