i got my "check engine light" on for about 3 weeks, it's code 67, but my mechanic told me to ignore it...cuz i got the same code before and he reset it for me, but after 1 week, it came on again, that's why...anyway, i just notice that the light went off tonight. does this happen to anyone before???

 

code 67 is Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system

 

gut that ****.. or just put in a test pipe.....


<-- sorry if i'm no help, but i'm in a bad mood..

 

Sounds like you need a new Catylic converter....time to get a high flow!
