2005 pontiac grand prix catlyst and evap monitors
Do i have to do the whole GM drive cycle to get the catlyst and evap monitors to read ready everything else is ready i really need to get it inspected.
Re: 2005 pontiac grand prix catlyst and evap monitors
yep, fuel has to be over 1/4 tank, should be below 3/4 tank for many tests to run. Some cars need the car to sit overnight to run evap cycles. Ambient temperature will also affect some tests. Just drive normally and it will usually reset in a day or two.
