I think the 0171 code is because of the Intake
. If the Intake
is cold-hence "cold-air Intake
", it makes the computer think that there is a hole in the Intake
so the check engine light will come on. If this is the case, the light will come on during cool nights. (too much cold air). It doesn't hurt the engine, it's just specified in the computer to tell you when something isn't "factory". I've driven mine like this for 2 years and it's been okay. I'm just
because the computer is saying the O2 sensors are bad, and I just put brand new ones on them!
