Hello!

What do these misfires mean?

I also have misfires P0134, P0135, P1300 and P1319.

I believe the first three are O2 sensor related and or plugs.

I can't seem to figure out the misfires though..

Please HELP!

 

How many miles on the truck, when was it last tuned along with wires?
If you are over or near 100,000 miles replace all 4 02's also the wires if they are the stock grey wires.

 

I am at 65k miles. I ordered one O2 sensor and Ignition Coil Pair. I don't know if they are the stock grey ones, the mechanic has it right now. The service engine light came on and it had all of these errors. Do you think that the codes will go away once these parts get changed out?

 

First two are O2 codes, second two are multiple random misfire and low fuel misfire codes. Mechanic will clear the codes when he is done, now if they come back he will have more work to do ;-)

 

Cancel the order for a coil pack, you don't need one, if your wires are original get a set of 8mm STI wires ordered from British Parts of Utah for $70.
Get the wires and plugs replaced.
As for that 397 code, that is not a good Rover fault code number.

 

It worked!

The wires and spark plugs were changed out and now the misfires are gone.

Thank you so much for your help!!

 

Glad it worked out so easily.
