hello everyone i recently has a ap catback axhaust put on i was told the check engine light would not come on i got it put on last friday and yesterday the check engine light came on i took it to mazda and they said they wouldnt do anything cuz it would void my warranty. they hooked it up to a computer and they said a bunch of posibilltys came up the guy believed it was the o2 sensor does anyone have any ideas?

if you installed it with the catless midpipe, you will get the CEL.

help
 

is the catless the same as the cat delete pipe and if so would it come on a week later also it has been idoling a lil over 1 some time if its in neutrual it goes up and down sometime

yes they are the same. you can get it to clear if you disconnect the negative terminal but it will come back in eventually. only way to make it go away permanently is to put your cat pipe back on.

help
 

so the cat pipe from my original exhaust and whats up with the idoling problem

^................or mask it with the Cobb AP right?

help
 

i have a 2010 cobb doesnt make one for my year

no cat= cel.....try a spark plug defouler...or wait till an ap comes out
