The wrong room to post in fella would have been better in the Car related general room,

what car is it? could be a multitude of reasons causing it and its usually the process of elimination with these sorts of problems,

a few good tuners over your neck of the woods and I'm sure the PF massive will advise

a bit of constructive critisism with regards to your post its written in the 'text talk' style which is not really a favourite on PF

Good luck with getting the motor sorted
