Names Kevin. I’m from the United States. Just got a 2000 Prelude 5spd base a couple weeks ago in immaculate condition. One owner and was JRSC at one point. Full Mugen exhaust, good car good parts. Only issue I have is my emissions monitors never staying on ready/complete. Have replaced backup fuse, checked the ECU fuse. I have a OBD scanner, that’s how I know the monitors keeps resetting. No CELs whatsoever, no driveability issues just can’t get past emissions. The previous owner did install an in-line switch to the ecu to reset without having to exit the car. Today I will check that wire and make sure the switch isn’t broken or the wiring isn’t either. Any insight would be useful.

Hi, whats 'emission monitors' precious?

Clean or test or maintain the bits that make it burn dirty. plugs, wires, dizzy, valve clearances, fuel filter, egr etc etc.

Hi and welcome
