Review on 🔧 Enhance Engine Performance with FRAM FV163 Positive Crankcase Ventilation (PCV) Valve by William Dean

My Grand Caravan 94 randomly turns on/off the check engine light while driving, poor mileage, a gallon of gas is only 10-12 miles, my car hesitates, sometimes loses power while driving. I change a new EGR, still bad mileage, car still hesitates. We fill the Sea Foam in the gas tank, the mileage is bad, it still fluctuates. Replaced new spark plugs, still poor mileage, still fluctuating. Change oil more often, mileage still poor, still fluctuating. Chrysler's original PCV still rumbles nicely, but I changed it anyway. Now no more hesitation, the car runs smoothly, the most spontaneous thing is that the check engine light no longer lights up.
