took my car in for a diagnostic and had a new battery, MAF sensor and fuel pressure regulator.
The car feels better than ever to drive, nice and smooth and feel like some of the power is back.
However, i usually got around 600-650 from a tank so I averaged 45mpg.
Now ive noticed when I brim the tank im getting around 500miles.
Ive checked that there are no fuel leaks, brakes binding etc and the car recently had a full service so what could the problem be?
Ive also noticed a high pitch whistling when driving at around 30-40mph.
This only happens when the revs are constant and goes when I accelerate or decelerate.
I dont know if this is related to the leaking intake manifold that I repaired in my last post
thanks
