Check engine light?? - 6/9/2004 12:17:45 AM    OrangeCivic Posts: 24 Joined: 6/9/2004 Status: offline I have a 93 civic cx and just put a 4-2-1 header on it and now my check enging light comes on after about 5 to 10 min. I still have the stock oxygen sensor and catalytic converter on as well. There is also a cat back system already installed prior to the header. Any ideas on how to fix this problem?? Post #: 1

I have had ppl tell me having the cat on will mess my oxygen sensor readings up, ever heard of that? I also have a cool air intake but that went on after, dunno if that would make a difference?

It will reset the computer in your car and force it to relearn everything it knows. _____________________________ -brian (in reply to green98lxsedan) Post #: 6
