my check engine light has been on since the swap. I just ignore it.

Its code 91 (fuel tank pressure sensor ) something to do with fuel mixture... i found out upon investigation that Vtec and non vtec have different fuel tank pressures (believe it or not) so in order to make the check engine light go off, I have to go get a 97 civic EX fuel tank pressure sensor.

Get out the Haynes manual :thumbup: and read
