ok, fitted my new o2 sensor ( not from Honda but recommended from here ) I also serviced the car at the same time . after this I took it out, vtec would not kick in on the first go but was then ok but it dose not seem to pull as hard as it did before the new sensor. the car is kpro'd so would the new o2 sensor make it lose power ? any help is cool. it could just be me as its a new car and I'm getting old lol
