Eh? How would a MAF help troubleshoot worn rocker arms?
MAF measures volumetric air flow entering the engine. Worn rockers do not open (lift) the valves as much as good rockers do, hence lower volumetric air flow through the motor across the entire operating range and engine is much less efficient.
From experience by others on this forum and established baseline data, it has been determined that lower MAF numbers at idle indicate worn rockers.
LO teens are bad, high teens are good!
You have to have a scanner tool and software that allows you to monitor certain engine operating parameters to view the numbers!
