My Check engine light came on indicating some emissions problems but the engine is running quite nicely. I have followed the instructions from
formatting link
and Bay 13 -- I have read the engine code and I get 1-1-1 indicating No Stored Fault Codes. I erased all the codes anyway but the Check engine light is still on. I disconnected battaery (negative) for two hours and when I connected the battery, the Check Engine light immediately came on. Does that indicate a rusting/ loose wire or other hardware problem? Since the OBD1 is indicatind 1-1-1 (No faults), I don't thibk it will help to connect it to the computer at the Volvo dealer for $85. Please help with any suggestions.
