Question about Land Rover Discovery

Open Question

I have a Landrover Disco2 and I have multiple misfires on cylinders 1,4, and 6. While running the car runs smooth but when sitting idle and with the air conditioner on the car stutters and wants to shut off. My gasmilage is noticably worse when in this condition. I changed the spark plugs but the problem still persist. Can you help me?

The code description is a giveaway.
It could be one of the coils on the coil pack. Most coils nowadays do two cylinders each. This way car makers can get away with one coil for two cylinders.(lowers costs) One spark fires the air fuel mix in one of the cylinders and the other will fire the cylinder on the exhaust stroke. If the coils are removable, and you are fairly handy with cars,switch two around, the problem will follow the bad coil.

some weeks ago i had similar problems with my 2001 s60,i cleaned the etm and fitted a front o2 sensor ,its now idling at around 800 and driving fine.You could try changing the o2 sensor-but remember the earlier etms are troublesome and it may be a big part of your problem,the cleaning can work in only some cases

you have a bed coil (s). That's what causes misfire. Your DIC should be specific about which cylinder coil you're having trouble with.

And for .......

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

My check engine light is flashing, the car runs rough until I get up to about 30mph and it is running through gas like crazy


Sounds like you have cylinder misfire. Any of the large auto parts stores can run an OBDII check and tell you which cylinder is misfiring (not firing). The engine is running with one cylinder out causing the rough idle. The faster the car goes the less perceptible the misfire is. That is why at 30mph the car seems to run smooth.

Trouble codes for saturn ls2 car is showing the following trouble codes. po300, po306, po451 p2bo3 and c112b


P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.
