Thanks much Doc but what the others are getting at is the massive lack of details in your post?
We can't remember what car you have or what engine and we can't for sure know what after market mods you have done to the car.
All that matters greatly!

So we are not going to be able to give any kind of valid advice with the lack of information.
Why don't you put your car details in your signature as suggested above so you don't have to explain everytime what you have?
It would be much simpler that way.
