The ECU is such that it will reset itself eventually, but if you want to help it along, resetting will do this straight away. Like you’ve already said the car needs to be warmed up first.
Step 1. Warm up car
Step 2. Turn engine off and pull the hazard fuse ~ 10A (this is for the siR, probably the same for your car, mine is located in the fuse box under the hood/bonnet).
Step 3. Wait 15-20 sec’s and put the fuse back in.
Step 4. Turn engine on and let it idle for 10-15min. DO NOT touch the gas/accelerator pedal!
Step 5. Turn engine off.
Step 6. You’re good to GO!
This will allow the ECU to learn the new settings, i.e. how much air is coming in to the chamber, thus altering the amount of fuel accordingly.
However, as Setanta already said, the K&N have a very poor design, most of the induction kits for the CRX’s/Civics bolt straight onto the throttle body, which is the last place you want it as it’s fairly hot their! You will loose power sucking in warm air. If this is the case, you need to get a induction pipe that positions the cone filter near the battery and add a cold air feed from the front of the bumper.
Aftermarket induction’s will loose you low down power and increase top end power, so take that into consideration. How do you know it’s actually loosing you power? Just feeling it is probably not the most scientific way, put it on the rollers with both setup or a cheaper option is to take it on the track (but this is less accurate).
Also as someone has already mentioned it could be your restrictive silencer.
