Cooling fan on the 500 is constantly cycling on and off ever 10 to 15 seconds in 85 degree weather. Is this normal? Everytime it cycles it creats a 100 to 200 rpm dip and change in idle.
I had it even with the ac off at first then Lund made a few tweaks and now it is present only when the ac is on. Maybe a tuner can pipe in with if this is normal and fixable
