Throwing parts at a code hoping it will go away.....only a honda guy. You have to diagnose first, then replace the part!
P0421
Warm up catalyst efficiency below threshold
Here is the t/s info....good luck! You sure you can handle this...
I am also assuming you are out of the 7 year emissions warranty?

First of all i asked for advice not for u to talk **** on my thread so wtf dnt asnwer if u aint got **** to say dick head fyi smart *** i did my search and aint **** come up but a whole bunch of bull**** bout takin it to the dealer so take a dick nd shove it.
since it looks like you want to shoot a few rounds at the mitsu product... I own a lancer, and a honda. My honda's got more issues than my lancer, and you don't see me go on honda-tech.com and open a thread like you did.
Google the god damn code ffs.
Or at least search it on this board.
If there ain't a million threads about it on this board, there isn't a single one.

I got better things to do than read your e-thugin bs.
Change that diaper of yours, I think it's getting full and possibly messing up your temper.
Help your-self and we'll be more than willing to help you.
But don't forget... help your-self first.

Please attempt to spell things right, people give you more respect that way, and in the end, more of their time.
