[QUOTE="phillyefan, post: 2372039, member: 818117"] my car failed the emissions and I'm trying to find out if there's any way I can fix it without having to spend too much money on a mechanic. The printout said failed HC and CO tests at cruise speeds, but passed at idle. Everything else was fine. Also a note that the engine was just swapped in the other day, so it could be that it needs more time to break in but I need to pass emissions asap as my car is needed for work. The numbers are: HC limit at cruise, 150. Mine was 192. CO% limit at cruise, 1.1%. Mine was 2.53. During idle it passed very comfortably. Also the car is an accord, with a prelude engine. the accord is a 1990, but the engine is a '97 [/QUOTE]
