So i have been getting the p1259 code on my 2000 gsr. I just got the car from an auction and it drove fine for a few days when i hadn’t hit vtec once. I decided to hit vtec finally and it was fine until i went to take the car out later... cel came. The vtec stays healthy and when i clear the code it doesn’t come back for an hour of driving. Any ideas on what it is? Again the cars drives no different with the light on or off.
