I have an 05 TL that's not passing the inspection. It sat for a while but when i go to the inspection place..the mechanic tells me it's not ready for inspection. He can read the info from my car but somewhere in the process it stops. he says it's something to do with the drive cycle? i have driven for more than 3000 miles and all in vain. therefore I'm calling for help..does anyone know what the problem might be?
