Hello everybody I recently bought a 1995 Honda Odyssey nice interior and exterior drove great was warmed up I paid 1000 I was super happy got home noticed it had 389950 miles on it anyway I failed emissions I noticed the front oxygen sensor on the exhaust manifold was Obviously cut I failed carbon monoxide I have never seen such a dirty air filter on a vehicle and it started idling weird I replace the iacv blocked off the f i c v change the oil reassured all the battery connections are good I get cold one and code 14 even though I replaced idle air control valve I did clean the map sensor with brake cleaner which is bad I tried using a propane bottle with a hose to find an intake leak to no avail I am at a loss I thought it might be that easy m but I don't want to just go change and things *****-
