Hello,
I've deleted this fault code on my Forester 2001 non turbo, but after a few short journeys it keeps returning.
'Apparantly' this means misfire on number one cylinder.
It doesn't seem to misfire, seems to run fine. Though i put in new spark plugs and swapped over the newish HT leads... the code still returns. I pulled off the spark plug cap with the engine running and yes it misfired, so normally it seems to run fine, though i have to admit that it doesn't quite have the same power that it used to, which I suppose is normal for a petrol motor with 160,000 miles.
I'm wondering if other owners have had the same code with the same lack of noticeable misfire?
What is the most likely cause? And am i best to just ignor it?
Is there any problem with constantly driving with the check engine light illuminated?
Thanks for any helpful replies.
Ben
