I have not run out of gas ever, the car just started to run crappy? It did run pretty low once, but not empty. I guess the best thing to do is to change plugs and wires and go from there. I looked at the wires that are in there now are numbered, so I am assuming they are original. The plastic cover over the front plugs has bolts that looked a little stripped so I am assuming the cover has been off before. G Pappas, thanks for the input although I did not understand a whole lot of it. The guy at autozone only got the one code after several tries. What are the best plugs and wires to use? I got one input on motorcraft 9mm but the car is basically a daily driver, and I don't have a huge budget. Thanks for the help so far.
