i just installed headers, cat, and cat back on my 2000 civic ex. but now im having idle problems. we were extra careful with the o2 sensors when installing the new exhaust. anyone have a clue? do i need to reset the ecu or tune it differently?

 

Please describe the idle problem in more detail.

Reset the ECU by removing the 7.5 A BACKUP fuse in the under-hood fuse box for 30 seconds; then, reinsert the fuse.

If the CEL is ON, here's how to retrieve the code:

my idle sensor is bad in my '96 civic EX and it flucuates between 1 and 2 grand when sitting at a stop light or whatever.
