I have a problem with my EVAP system that keeps generating P0442/P0455. I plan to fix this when I can afford to, but in the mean time I've been connecting my scanner and deleting the code every time the check engine light comes on. Is that bad practice? Obviously best practice is to fix the problem, and I am, but is there a finite number of times you can delete these codes before you cause more problems? What kind of storage technology is the ECU using for this? ROM? RAM?
