my car knocking sensor needs tuning as my new exhaust is a de-cat and keeps knocking the sensor out of order. my car is lacking torque and so the sensor requires adjusting. does anyone know how i can do this?? can it be done DIY eaily or has to be pro. how much would a new knocking timer be??

if by the way anyone thinks it might be something else or a combined problem please let me know.

like i say, the car lacks power and does not have that boost feeling like it did. its 0-60 has considerably reduced and feels like as if iv got one foot slightly pressing the brake, while the other is flooring the acceleratorr.

im worried, i dont want to be beaten on the streets by a corsa or a similar ****emobile!!



please help...

many thanks.

Pete
