Hey fellas: Does anybody know a really good fuel injection mechanic in our area that can look at my Vortec 350? I've had a long history of running rich on one bank of cylinders that keeps on wiping out the associated catalytic converter and wasting gas.
O2 Sensor off that bank has been replaced several times(as recently as 5,000 miles ago). Check engine comes on every once in awhile with the same rich code. I can't remember the exact code anymore, but it's been the same. I've lost O2 sensors and catalytic converters on the same side consistently. I just want to identify the problem and get it fixed.
