hello guys i 've a small question.
can a worn camshaft cause detonations?
I have problem of detonations only on middle throttle and when I accelerated brusquely, I already checked timing (12 degrees at idle) and afr (14.6 on light/middle throttle 11.8-12.2 wot full boost). the engine is standard with standard boost pressure.
the detonations disappear only if the retard the timing to 5-6 degrees
any advice will be appreciated
thx
Marino

edit: today I was in 4 gear at 2500 rpm, i have accelerated and, over the detonations, I noticed that after the peak, the boost started to decline according to the rpm. in 4500 I was only 2 psi boost
