is the check engine light on???

Roy

yes seting nock sensor code po cercut malfunchin

is that the only code???
the knock sensor is in most cases a ghost code for another code


Roy

yes a airmeatering coed allready cleard

clearing does nothing for fixing the issue. it erases vital info for diaging it.

never clear a code till the problem is identified and repaired.

mass air flow code will not cause issue. the crank sensor controls injector pulsing issue

Roy
