Hi, I have a 1995 Olds Aurora and the check engine has been coming on. At first it only came on after idling for a coule of minutes but never when driving. Now it comes on almost imediately after starting the engine. I have tried to read the codes but I can not get the reader to work. I have also had the guys at the parts store try and they were also unsuccesful. When connected it sends back an error messege saying cannot read codes. Even though its a 95 I have to select 96 OBDII and use that cable to connect and it reads connected but will not scan. Is this a common problem? I think we peobably have a bad oxygen sensor as our milage has dropped a from around 19 city to 14. Also hetting more of that unleaded fuel smell and used to not smell that way.
Just learned that 95 Aurora's were built during the change from OBDI to OBDII so it seems that they installed a OBDII port with a OBDI compatable computer so most code readers can't access the computer. Guess its time to take it to the shop.
have the same problem?
