I have a 1998 Civic DX...and I installed my AEM CIA. After driving for a day or so, my 'Check Engine' light came on...figuring it was b/c of my O2 sensor, i reset my ecu, and of course it went away , but it's back again , NE ideas?

Help Much Appreciated....

 

Have you checked the code? I have a feeling it couldn't be the O2 sensor if you just installed a CIA. Maybe something's just disconnected.

 

Alright, I might sound stupid, but what code?

 

Here ya go:

The site's also got some other pretty useful info. Let us know what you find out.

 

Thanks Man.

 

Make sure all your clamps are really tight and you no vaccuum leaks, and they are all connected. That usually throws a code.

 

Did you install the IAT into the pipe and reconnect it?

 

Yea, I did check the IAT....

Also,
I checked the code using that stupid papercclip method, and it came up as "Evaporative Emissions System Control Leak in Gas Tank Area"

I thought mabye my gas cap is loose, but i checked it and it was on really tight, so I'm still lost.....ugh

 

How about the gas cap gasket?
