If you can please list the code that was read and also the symptoms for me I may be able to give more specifics on the code itself. As for a misfire in any cylinder I will lists some things that are indicative of this.
Spark Bad fuel injector
bad 02 sensor
out of gas
bad catalytic computer
burned exhaust valve
Symptoms can be a hard to start engine.
Hesitation or bucking when accelerating.
A rotten egg smell from the exhaust can indicate a bad Catalytic Converter.
If it has been a long time since a tune up then plugs and wires may be in order.
blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage
the oxygen sensor is located in the exhuast pipe,there could be more than one sensor, maybe 4 sensors on a 6 cylinder car and 2 sensors on a 4 cylinder car,so youre gonna have to know which one is bad,if the check engine light is on it will tell you which position sensor is bad like bank 1 sensor 2 something like that,also there is NO fuse for the o2 sensors
White smoke from exhaust indicates burning coolant. Blue smoke from the exhaust indicates burning oil. In replacing the valve cover gasket for an oil leak, some smoke from residual oil is normal but it would be excess oil burning off on the manifold from the engine compartment, not the exhaust. Hope this helps with your question. Greg
I have had this issue. You may have noticed black smoke coming from your tailpipe when you step on it as well. There are two oxegen censors on your exhaust likley under the passenger side of the car close to where the passenger seat is. These will likely need to be replaced. Sometimes you get a check engine light as well when they are bad.
The second hing is to check your filler tube as it may have a seperation and the fumes are coming from there and you can also be leaking fule from the same location.
