Fault codes - Trouble

[Trailpimp]

Just got the fault code P1300 "catalyst damaging missfire, multiple missfires"

what could cause this? I just passed 60K miles and have an service scheduled for Monday. I am assuming I shouldnt drive on this?

Any help would be greatly appreciated.

Good chance your plug wires are gone, your plugs are syre warn out at this point.

So replace plugs and wires? I am assuming catalyst and the cat converters? These hopefully wont need to be replaced, or will they. Also it is safe to drive the 10 miles to the dealer?

Thank you!

Dan:
Go ahead and replace your plugs/wires, but beware this is a classic error code for the dreaded sticking valve issue so common to these vehicles.

How are you reading the codes? Generic OBD-II reader?

Yes, it is a generic OBD II reader. It is a 2000 disco. I will have the mechanic check it out on Tuesday. Thanks for your help!

Have fun replacing the wires! If I ever find out who's idea it was to set the coils up in that fashion, I'm gonna string him up!

What a pain! I hate motronics engines! Engines without distributors are the devil's child

If the light is solid, drive on it. If it is blinking, do not drive on it.

If your OBD II code reader has freeze frame data, then find out when the fault occured. ( out of 10 of my CEL's occur WHEN STARTING THE VEHICLE, or shortly there after. I log the date, code, and conditions in my logbook, clear the code, and go on w/my life. I do look @ the pending codes & I do repair my Rover as needed, but unlike the "American" brands, the Rover CEL stays on until it is shut off by someone. A ford for instance will usually turn itself off after X# of "clear cycles", where as the Rover, to my knowledge, will not. Thank You, LRW.
