Default Anybody had crappy afr\idle after cutting J12?

sup
my car idles like crap.
somtimes afr's jump to 16-21 :1 and the engine keeps runing on that range for a few seconds.

could it be because i had to cut the J12 resistor?

thanks.

nope, it hasnt to do with that.. J12 is for datalogging with UD for example (no cutted) or crome For example too (it's necessary to cut it)..

Check ur map. or what Dmc1 said..
