failed on hydrocarbons at 1771 rpm.
limit 54ppm. Reading 92ppm
passed in all other areas
250,000km. Never failed before.
I checked all of the vacuum lines. I replaced most of them least year. They appeared to be all tight
I think i found a sticky canister purge valve. Now it regulates on and off every couple of minutes. Could be the first time i am ever hearing this valve. It may have been ceased for years. Would this repair be a help?
I also have a few holes on my rear muffler. Nothing loud but a few perforations around the clamp. One in my front muffler too. Does this have an effect?
Any other ideas?
Thanks
