    Choppy idle

    That older plug doesn’t look like oem. Plugs are supposed to be changed every 100,000 km/60,000 miles…

    I took the leap...

    Ensure ALL the fluids and filters have been changed. Many of us stick to the maintenance schedule for adverse conditions or heavy use.

    First post- going to look at a LR4 soon.

    I don’t think there will be any need to swap out an scv6, if you keep up on the maintenance…. of course that implies the previous owner did. And they are big and heavy…. so suspension, brakes, wear quicker. But those 5k oil changes are necessary. Now that I have mine sorted, I’m quite happy.

    LR4 Fuel Issues after alternator fail

    Could be…. but pinpoint test #1 still needs to be passed. I can’t imagine “tinkering” without the workshop manual. If you send me a PM…

    LR4 Fuel Issues after alternator fail

    A reading of 12.2 is a battery at about 30% capacity. Not enough to power up all of the modules of the vehicle. See https://www.varta-automotive.com/en-gb/knowledge/articles/article-details/car-battery-testing-instructions

    LR4 Fuel Issues after alternator fail

    Well, the Denso SC2 is the original generator. And compliments of the PCM, the output is variable, by design. But I still can't buy that affected the fuel charging system. Insufficient voltage will ill affect most modules. Out of interest, with the vehicle not running nor a battery charger not...

    LR4 Fuel Issues after alternator fail

    I can’t buy your hypothethis. These are independent, protected systems. And as I know nothing of your particular vehicle, it is difficult to weigh in. Does your vehicle incorporate a BMS. Do you have the correct (and healthy) battery for your vehicle? What complete set of DTCs are thrown, please?

    New Tires to replace Cooper Zeon

    hmmm... I'm not too far from Rochester and I do cut through the Adirondacks on the way to VT in all the weather, in all the seasons. We will have to agree to disagree; imho all season tires are not suitable for winters here. period. As a result, Michelin X-Ice, Bridgestone Blizzaks, and...

    First post- going to look at a LR4 soon.

    You are correct on both accounts @f1racer328 As I shared with the OP in another forum... Knowlege of the maintenance history is paramount.

    Proper coolant direction for the Supercharger

    Looking forward to an experienced reply… but is your perspective based on the “input” to the radiator or the “input” to the supercharger…

    Thoughts on these spark plugs?

    I wouldn't suspect those spark plugs as the root of your issues. Clean paper air filters, clean maf and clean throttle body is where I would look first.

    Block Heater for LR4

    I like the out of the box thinking... The Ford 3.0l ecoboost engine has a number of block heater choices by a number of suppliers... ZeroStart 3100121 ??

    Longevity and Investment

    I hear you about the engine troubles some have experienced…. preventative maintenance is everything. (knocking on head again, this week) Mine runs noisy, but perfectly. I do have the oil and filter changed every 5000 km. That should keep the premature wear at bay. A close friend with...

    Project Dark Knight Rising

    i was thinking, have a look at the jaguarforums.com site. Especially the x150 forum. Many play with sdd and upload just the engine tuning components of the software… worth a shot.

    2012 LR4 coolant leak

    Its a little more specific... SAE 5W-20 Full Synthetic conforming to WSS-M2C925-A An example would be Castrol Edge Professional A1 or Motul 8100 ECO-LITE 5W-20. I believe its 8.0l with the filter change. The wrong oil and infrequent oil changes have been blamed for the premature timing chains...

    in a word…. “nope” I don’t think you’re pressing your luck if you keep up on maintenance. But please don’t use the word “investment” ;-)

    2012 LR4 coolant leak

    @CindyLR4 , welcome back! Sorry to hear of your loss. Now we are getting somewhere. You started this thread with the title “coolant leaking”. And it is possible that it is leaking from many places, though that would be very rare, indeed. Coolant can leak at the oil cooler. It can leak at...

    vibration at idle - motor mounts?

    +1 on @Longtrail ‘s suggestion. Looking forward to an answer from a pro, too. (@Rover Range , where are you?) The only way I know how to check a bushing or mount is to check for movement/play. And I do that with a pry bar. Would a scope/camera work while at idle? But I think you are have the...
