Mike,

My disco II's service engine ligt came on at 51,500 miles it went off so i thought it was a reminder. Well it came back on at 52, 181 miles and now the truck runs mildly rough between 25 - 35 mph. How can I get the codes read, do they do that at Advance Auto or Auto zone?

any suggestions?

Went to Advanced auto got codes read:

P0154 - O2 SENSOR CKT NO ACTIVITY(BANK 2, SENSOR)

PO442 - EVAP EMISSION CONTROL SYSTEM LEAK (SMALL)

CAN ANYONE HELP WITH THESE CODES?

 

yeah, i go to autozone and or advanced and they read the codes for me all the time. its free.
