1999 Chevy Suburban V8 Four Wheel Drive Automatic 138000 miles
Check engine light is on. Used my OBD2 meter & codes 140 & 137 came up. I changed all sensors, cat convert, transmission, & transfer case has been recently changed. Check engine still on. There was a wire lose going to the oxygen sensors & I had it repaired. Check engine light still on with the same codes. What else can it be?
have the same problem?
