Somehow I don't think the fuel pump relay on Honda other models has anything to do with an S2000.



If the car is actually misfiring you will eventually get a CEL and a misfire DTC stored. No DTC, it's not misfiring.

Did you replace the spark plugs as a result of the misfire? or is this something that happend after the swap? 9 times out 10 a vehicle is not going to get huge hp or performance gains out of "performance" plugs.

no i got the new spark plug from dealership and coil. but i still have that misfire feelin...
