My '96 civic EX has been getting around 350 miles per tank full for as long as I can remember. All of a sudden in the last month or two I barely get 250. Driving habits have not changed and I was wondering what could be the cause of this sudden loss in gas mileage? I do not smell fuel and had garage check for fuel leaks but they found none.
I did a major tune up including fuel filter but minus the pcv valve, which I will replace with next oil change; checked and fixed tire pressure, which was a little low 25 vs 30 fronts and 25 vs 29 on rears; the 02 sensor was replaced this past summer.
The car is leaking oil but I'm not sure from where exactly but after steam cleaning the engine last week, I see oil under the valve cover and distributor.
I did notice that when idling the car sometimes idles with a bit of a rough vibration. It kind of feels like when A/C would kick on but I'm not running A/C this time of year.
