Engine Performance problem
2001 Mitsubishi Eclipse 6 cyl Front Wheel Drive Manual 104xxx miles
My mitsubishi has been misfiring 2 days after I have put in premium fuel. The code; P0301, misfire, cylinder 1. About a week or two, I noticed that if the car starts misfiring, I can restart the car, and the misfire would go away. Today, coming back from work, it started to misfire, then died. I tried to restart, but the car would die again, then I restarted and held the gas pedal, at about 2 - 3k rpms, then the misfire went away. Then when I got home, she died out, and will not start unless I keep my foot on the gas.
Replaced with no change in performance; wires, spark plugs, coils, distributor cap and rotor, cylinder 1 injector.
I also noticed that, when I turn my key to ON position, I cannot hear my fuel pump pressurize. Could that be the cause of the whole problem? And could the fuel pump have thrown me the P0301?
have the same problem?
