check engine codes - Land Rovers Only

apbtpetey · 11-27-2006, 11:33 AM

I have the following codes being thrown on my 97 disco

p0300
p1314
p1313

any clues?

apbtpetey · 11-27-2006, 11:40 AM

Well I have a friend at a local shop that is looking at it for me and those are the codes he got from it. He checked and the spark is fine and fuel pressure is fine. He is leaning towards possible MAF, but at almost $700 I really dont want to be guessing at this and that. I started a thread about what is doing so for more details just look down a few more threads. He replaced the vac lines that were bad and I am still where we started from.

John,
The 300 is mutiple misfires, random
1313 and 1314 are failed cats.
No MAF at this time.
You need to start looking at what is killing your cats, plug, wires, coil, dirty injectors, coolant leaks.

well the plugs and wires were just replaced and the tech said the spark is fine. Does this mean my cats are done? Coolant level is fine and hasnt gone down much at all. I do have a small leak at the thermostat, but that wouldnt cause this problem would it? The leak is very very tiny

Cats are junk for all intents and purposes. How bad were the wires and plugs and how long ago were they replaced, they could still be the problem that killed your cats.
My only concern is that if you can't verify what killed the cats, it will happen again and that is getting expensive at that point.

the wires were fine nothing bad looking at all. I changed them out on Saturday thinking that was what was making it run rough, but it wasnt.

The plugs I changed out the begining of the month and they looked pretty normal. One or two had a little bit of oil on them, but very minor

Your cats may be contaminated. The ECU is seeing the pre and post oxygen sensors. Try to get the cats first by geting them up to operating temp.

First clear the codes off the ECU and put a fresh tank with premium and some octane booster. Run it for 30 miles

LET THE CATS GET HOT.

If they are good, the crap will clear out. Second, think about changing out the oxygen sensors if they have not been changed. Oxygener senors get ruined by leaded gas, oil in the exhaust, and of course old age.

John,
How many miles on the truck?
When you say the engine is running rough, go into more detail.
You may want to consider a compression test just to make sure those wet oiley plugs you replaced are not indicators of head gaskets or valves and a leak down.

It has just over 148,000 on it. I replaced the head gaskets over the summer. When in there everything looked great.

As for the running rough here is what happening:

It is stummbling, but stays running. It stalled out on me the other morning and it took about 1/2 hour to get it to stay running without my foot on the gas. As soon as my foot was off the gas it would stall out and take a few tries to get running again. Once it was warmed up it ran pretty good, but still felt like it wasnt 100%.

I talked to my friend again this morning and he said that when he disconnected the MAF sensor it ran fine and he is leaning towards that, but I really dont think that is the problem at least not the only problem. My mom had a car that had bad cats and it did the samethings that my Disco is doing, stalling, loss of power, not keeping a steady normal idle.

Here is a link to what started this all,

If you unplug the MAF, you are basicly turning off the ECU's ability to manage your engine, NOT GOOD.
I understand that you are wanting to try anything to get it running again, but go and try everything people tell you to do till you research it out. You have no MAF related codes so don't go there.
Have you looked at the fuel system, fuel filter, relay and pressure when running at idle and 2000 RPM's as well as when turned off for an hour or so?

I didnt touch the MAF, it was somebody at the shop that did, and I spoke with them again reminding them not to mess with the MAF becuase I didnt think it is the problem. I was just updating on what they have done/tried. They said that they checked the fuel pressure and its fine and that there is no fuel related issues. I also told them that I am not buying a MAF sensor becuase I will not spend that kind of money on a guess by them.

Disco Mike · 11-29-2006, 10:29 AM

I am out of ideas unless you come up with other codes.
Let me know how it goes.

Mike thanks for the help I think I am just going to pick it up from the shop and go over it myself, they seem set on it having to do the MAF and dont want to consider anything else.

I have an exhaust leak at one of the manifolds, would that have caused my problem? I really have no clue where else to look at with this thing. I mean they say the fuel system is fine, the plugs and wire were just changed, The one vac line they changed. I have a chance to get a y-pipe with cats & o2's for free (used, but still free). Maybe I should change it out and see what happens to the codes after doing that, I am not sure.
