2004 Fords Tauras, difficult stating, gas milage has gone down to about 12 MPG, all dash warning lights come on after start up-if you turn off ignition and restart-they go off?!? What's up?
Mine is the same way. We replaced the coil pack (it was mis-firing) and all the plugs and wires. That helped the rough start issue. I am getting, at best, 18MPG. I have had the fuel injection system cleaned and that did help for the first month or so get me up to about 21MPG on the highway. Not worth it to do it again. As for the lights.... mine we have determined is an electrical issue. That is pretty common. After thousands of dollars to have all the things replaced (some 3 and 4 times) the lights never went off. :(
sounds like your computer has a problem,have it scaned or reflashed,dealer is only one to reflash a computer,ia around $60.00.
