I have an 07 avalanche with plenty of mileage 170k , my gauge reads roughly at 20 at idle , on the road hits 40 , sometimes drops below 20 at a stop , when parked ive also noticed my lifters start ticking after a while of running the motor , it also has the afm system in it , any ideas as to what may be going on or why my gauge doesnt stay at around 40 when idling ? , could my oil pump be going bad ?
