making a CAI
 

hey, i was thinking about making my own CAI,
well i sortof started, i put a APC filter on and got rid of the whole stock intake... now i got a small problem with the what i believe is a O2 sensor.. it was just hanging there, so i stuck it in the filter that i got... so now that sensor is in the filter, it goes in right by the gasket that goes over the stock pipe, today i got a check engine light on... what can i do to make it go away......

Disconnect your battery for about 15 minutes...
That's actually a intake air temp sensor, but that alone shouldn't have thrown a CEL. If the problem persists, find out which trouble code(s) is/are stored.
