according the DEQ in oregon, the 98 vintage volvos are known for problems with their OBD-II system, the onboard diagnositcs system.. apparently the computer needs to have the car drive on the road at certain speeds and RPM's known as the "Drive cycle" in order to either reset the OBD values, or kinda of trick it. not sure...<p>anyone heard of this? the DEQ fellow sezs i should just get a fax with the speeds and rpms from the dealer to do it myself before bringing the car back. we've tried 3 times. im getting tired of this.<p>so looking for info on drivecycle stuff. thxs.
