If using an OBDII reader will not help as this will only give you the present codes
and since you don't have check engine light on all the time this will not detect any faults
if you are to use this OBDII reader you have to scan when check engine light on
need to have it scanned with a scanner it will give you more options as to look up history and different modules readings and codes
good luck
