2002 Oldsmobile Alero P0300 misfire code
2002 Oldsmobile Alero P0300 misfire code
I go to start my 2002 alero 2.2l and it has trouble starting... check engine light starts flashing... used a hand-held scanner and got the P0300 random misfire code. I've been doing as much research as I can and think that this my be an easy fix with just plugs and wires (perhaps even a coil) but the thing that is throwing me for a loop is that the ETS has been kicked off as is indicated by the "Trac Off" display lamp in the dash. Should this be a clue to point me more in the direction of a coil issue or is there other possibilities?
Re: 2002 alero p0300 code
The fact that the ETS light is on and traction is disabled is just a result of the check engine light flashing. There are many codes that will turn off traction control. A flashing check engine light means that the misfire is bad enough to cause possible catalytic converter damage. Yes spark plugs, spark plug wires and ignition coils are the common cause for misfires on this engine. Also a leaking fuel pressure regulator will do the same thing. When the FPR fails, it leaks gas into its vacuum line. This causes an extremely rich condition. It will usually clear itself up after a few hard accelerations.
