I've got a '00 Mirage, and I just put a new catalytic conv. on. The first couple of days after my car drove great, like it was new again. Then for some reason my car has gotten cold natured, really hard to get it to quit spitting and sputtering after i crank it, but seems to get better after it warms up. This all started about two days after the new install, when the check engine light started coming on. Does anyone know what could cause this, and what can I do?

 

well if your check engine light is on then go to autozone and get the code then come back with the results for us.

 

well, i did that, and all they told me is, it has to do with emission problem. i guess i can go back and see if there's a code.

if its an emmission problem then it might be a bad o2 sensor or something like that since you already replaced the cat. Yea just get the code and come back
