Can anyone help me and tell mw the drive cycle of my car
what is the drive cycle for my grand prix 08 on 2008 Pontiac Grand Prix
Good question. Each of the 8 readiness monitors have different protocol or driving conditions-requirements. Usually 5 or 6 will set fairly fast. Yours being a 08 model can only have 1 unset readiness monitor. A day or 2 of normal driving should do the trick. Keep the tank around 1/2 full because the evap. monitor won't run if the tanks near full. Try driving at highway speeds above 50 for 10 to 15 minutes also.
