Emmisions control valve. It wont pass smog without it, but will drive fine. Emmissions control stuff has a 5 year dealer warranty. What year is your Jeep?
Yeah, if you just put a piece of electrical tape over the light, you won't even notice it...oh well, it's a 99...
i'll have to take care of this soon cause that check
engine light is driving me crazy. it's all i can see by
the corner of my eye...
is it a simple fix?
