Hey all! New LR owner, loving it. Started throwing codes and idling strangely about two weeks ago, codes are P0171, P0172, P0174,P0175, P0455. I've replaced the maf sensor and cleaned the throttle body. I also replaced the fuel tank cap, changed the air filter and had the oil changed. The idling has gotten worse and now will shut off if left for a couple minutes, I thought maybe next move would be spark plugs but wondering if there's another solution? Any help is greatly appreciated I am a novice in this area but bought an LR3 wanting to learn.

 

Does that thing have spacers? What size rims are those?

Looks good, welcome to the fam. Rough idle....hmmm, coils? Plugs? Thermostat (for the stalling). That's all that comes to mind other than what you listed.

 

These engines are very sensitive to vacuum leaks. Make sure the oil fill cap is secure as well as the oil level stick. Next I would check the intake plastics downstream of the MAF, they have been well known to crack. Usually at the ends where the worm clamps compress. RTV sealant can help fill the plastic cracks. Then I would look at the PCV system, the tubes, and probably replace the PCV itself. Not hard to do, just have to move the intake stuff. Lastly check the EGR valve tube at the far back end of the engine. They can come loose.

 

I think its just the offset of the rims.

 

BMW M-Parallels on an LR3. Can't say I've seen that before, but not bad!
