i replaced the battery in my moms old buick because it had been sitting up for weeks dead. the tag has been expired since last year, so driving around in it is risky. i took it through inspection and the obd failed because the car hasnt seen 50 miles before the ecu starts logging error codes (this is what the person said) so i drive around the city putting on at least 50 more miles, risking getting pulled over... go back through inspection and fail again because its still not enough miles for the ecu to say "okay im ready to display any codes" this is bullshit. how does one know how many miles to put on a car before the ecu starts logging? and how fucked up is it to say your car needs xx amount of miles put on if your tag is expired, or about to expire? imagine people that are trying to get inspection at the end of the month having to go through this dumb shit... rediculous. what should i do? or be done? i really see now why this obd scanning is utter bullshit... keep in mind, the tag is expired on the car, so any driving around is very risky as memphis has turned into an army sized police run city would putting the car on blocks and letting it run be an option? or just plain dangerous?
