o2 sensor...

so here's a Q: anybody put on a cai to fix the prob with running rich? seems cheaper than putting on new o2's. then again if the eng gets more air isn't it gonna put even more fuel in?

A cai may lean it out temporarily, but it isn't a permanent fix. The computer will adjust for the new intake and add accordingly. How rich are you running? And are you having any trouble codes pop up?

sometimes the code comes up but i don't feel like spending a bunch for 2 o2's and then some more time under the car to replace them - my hands are too big for a japanese engine compartment
