    Range Rover Sport / L320
    Hi My Sport 4.4 V8 suddenly experiencing power loss, outrageously low mileage (4.2 km/l) and rough idling. The check engine light came on yesterday but haven't pulled the codes yet. Recently had it serviced with all spark plugs changed. The O2 sensors were also changed recently. Any ideas of...

    Range Rover Mark II / P38
    hi, Wonder if anyone one can help. the breather pipe that the hose connects too on the rocker cover just pulls out. Is this correct, I am assuming not, and its a possible cause for my rough idling.

    Hey everyone , decided to give the engine bay a clean today, and after I was all finished up I started the Range Rover...... And now it's running rough at idle, and while in drive. It shakes a subtle amount when in park, and proceeds to increase the severity of the shake when the Range Rover...

    Range Rover Mark III / L322
    Hi gurus I have switched from P38 4.6 to L322 (TD6 BMW Diesel, year 2003) a year ago. Happy with the ‘upgrade’ but misses the V8. The L322 has been running like a clock until a few weeks ago, where the problems started… Symptoms: I first noticed a brief loss in power/stuttering when travel...

  7. Rough Idle on Startup that has begun a full time problem

    Range Rover Mark II / P38
    Hey guys, Recently I had a rough idle on startup, which seemed to possibly be a cylinder missing. In the past as soon as I got some RPMs going it smoothed out and didn't return. Slowly over time the issue started to return when stopped at lights for a long period of time and such. Now it's...

    Range Rover Mark III / L322
    Hi, Just got home tonight and as I was getting into town, I noticed my 2006 full size was idling rough when I stopped at a stop light. Accelerated fine and seemed fine for normal driving but when I stopped in the driveway, same thing, rough idle. I shut off the rover, tried to restart it and...
  11. Slightly rough idle. Should I be scared?

    Range Rover Sport / L320
    ‘11 RRS SC. 85k miles. Of course the first thing I get scared of is... tensioners. Weve always run a minimum of 91 octane and have for the last couple oil changes started halving the recommended interval as I’ve read and been told that can stave off disaster. Im due for air filters, but...

  15. Off Road & Rough Road Ride & Performance HSE vs Supercharged

    Range Rover Mark IV / L405
    Off Road & Rough Road Ride & Performance HSE vs Supercharged Friends, since relinquishing my L322 I have been restoring my old Classic GDE while searching for an L405 which like all my past Range Rovers will most likely spend much if not most of its time off road. I am wondering what people's...
  16. Rough idle, no power

    Range Rover Mark III / L322
    I just purchased a 2006 Range Rover HSE 4.4. It is throwing p0026, p0028, p0016 and p0018. Just wondering if this sounds more like a timing issue and not a sensor issue. Any help will be greatly appreciated
  17. 2004 Range Rover POO11 and rough idle

    Range Rover Mark III / L322
    Sensor says Camshaft Sensor - Timing over advanced or System Performance Bank 1 I also detect a rough idle. I have been dealing with a suspected cracked exhaust manifold/cat on passenger side. Is this as straight forward as a failing cam sensor?

    Range Rover Sport / L320
    A while back my 2012 Range Rover Sport would run noticeably rough (exhaust was smoking more than usual, idled a little erratically, and the car just seemed louder than usual. Every so often during startup the Reduced Performance indicator would come on as well. Normal driving seemed to be fine...
  19. Check engine light on, rough idle, misfire #7

    Range Rover Mark II / P38
    I'm getting a misfire on the #7 cylinder of my '01 4.6. Mechanic did a quick check on it today and plug is clean (relatively new plugs and wires). So he then did a pressure test and said pressure is low in the cylinder. Reads 100 psi, (when I guess it's supposed to be around 150psi(?)). He...

    Range Rover Mark III / L322
    Long time lurker, second time poster `8) I've done a fair bit of searching on this, and am now just confusing myself, so thought I'd open a thread and get some advice on the exact issue. If I've missed something in my searching that's the same issue, my apologies, and please do direct me...
