i bought this car a couple days ago and it was sitting in the lot for a year, i took it to autozone because the check engine light was on and they told me that the cylinders 1,3, and 5 have miss fired so i changed all the spark plugs and put fuel injector cleaner in the tank and the light is still on. I went back and they told me that maybe the head of the engine might be bad that the 1,3, and 5 is on or the fuel rail. I've decided to give it a try and just do a tune up and change the oil filter and the fuel filter and see if that works but i need to know where the fuel filter is located? please help!
