Bad misfire dont know the cause?
 

i was wondering if a bad o2 sensor would give me a misfire but its all on cylinders so i dont know

Re: Bad misfire dont know the cause?
 

probably a bad coil

Re: Bad misfire dont know the cause?
 

how do you know its a missfire? and that its on all cylinders?

Re: Bad misfire dont know the cause?
 

check it out this is what i got when i scaned that how i figured out it was a bad misfire

my buddies tellin me its gotta be the o2 sensor he can get it for 100 is that pricey

Re: Bad misfire dont know the cause?
 

based on that it proably is an O2sensor. I have no idea about price though...sorry.

Re: Bad misfire dont know the cause?
 

Sounds like the O2 Sensor... to get a sense whether that is a good price, you can compare prices on-line at ECS website and others.


One bad coil will typically cause flashing CEL under acceleration, one cyl misfire, poor engine performance and black / smelly exhaust.
