I changed the
O2 sensor,
Fuel Filter,
and still the same problems.

finally i changed the Catalytic COnvertor and now all my problems are gone.
the CAT was completely blocked we put a light and looked thru and couldn't see the light on the other side.

if you still have a problem go to a muffler place where they can take out the CAT and have a look (won't cost much) 10 min job.
unless u have the tools.

if you can see light thru the CAT ur ok...otherwise change the CAT. If u don't it will ruin ur O2 sensor as well.

the Original CAT at honda is about $1100 CDN ouch!!! i got the jobber for $250 cdn installed.
