PK,
I have a 99 Accord and I know for a fact that my 99 accord has a "knock
sensor". It's my guess that your car also has a knock sensor since it was
also built in 99. It might be defective--just guessing.
If you still have the old plugs--put them in to see if they solve the
problem. I doubt that the bosch plugs are the source of the problem unless
they are the wrong type plugs for your car.
