Hi, any advice appreciated...

I have a '99 turbo, that appears to pink on light throttle, it clears up on full throttle although is very occasionally noticable whilst accelerating.. The air flow sensor was replaced but it has made no difference.... Any thoughts ? It appears to be worse when cold....

thanks

Matt

 

A few things please
Does the car have any modifications?
What fuel does the car run on?
What oil do you use in the car?
Just those for the moment ta

Back box only, running optimax, and fully synth oil..... apart from that standard - at the moment ! Thanx
