  1. Control problem during hard acceleration

    Range Rover Sport / L320
    Hello Folks, I recently bought a 2009 4.2L Supercharged. During hard acceleration on the highway it darts a bit from left to right and requires careful steering input to keep it going in a straight line. It feels like a front wheel drive vehicle hunting for traction in slippery conditions...
  2. 4.4 tdv8 acceleration hesitation when building speed

    Range Rover Mark III / L322
    I have a tdv8 4.4 and when accelerating hard the car seems like its hitting the rev limiter but its not as the revs are at 2000-2500. the harder the acceleration the worse the hesitation is . could this be a fuel issue or a torque converter issue . to myself the symptom does feel engine more...
  3. Radar cruise acceleration settings

    Range Rover Mark IV / L405
    I have a 2018MY full size with radar cruise. The owners manual tells me that I can change the speed at which the car "resumes" via the in-dash menu.... but I cannot find the menu. I can see how I change the "follow gap" via steering wheel buttons, but not the glacial pace at which the car picks...
  4. Input needed: rattle-like sound on hard acceleration

    Range Rover Sport / L320
    I've had this noise for close to a year, and haven't done anything about it. The only time it appears to diminish is after extensive driving, where everything is very warm. For this reason, I assumed it to be a loose fragment in the catalytic converter/loose bolt/clamp in some exhaust fitting...
  5. RR 2018 HSE acceleration issue

    Range Rover Mark IV / L405
    Just got my RR2018 HSE a month ago and has been at the service center 3 times. Since the beginning I couldn't deal with how slow it was compared to the one I test drove, being the main problem an acceleration lag whenever I use the brake for a few seconds (example: Stop signs, turning left in...
  6. 2008 RR SC Falls Flat On Hard Acceleration

    Range Rover Sport / L320
    Ive been reading through this forum for years, we now own 2-2008's. 1 RR Sport HSE, 1RR SC. The supercharged runs great but seems to fall on its face under hard acceleration. There seems to be a "sweet spot" (about 30% acceleration) that the supercharger will make her move quick, but it just...

    Hi all, I've done a few quick searches but couldn't find anything definitive to help me so I'd like to ask for your help in brainstorming what could be wrong with my Rover. It's a 2004 HSE 4.4 M62 with 110,000 miles and the symptoms are as follows: when accelerating the front end wobbles...
  9. Acceleration Causing Electrical Problems?

    Range Rover Sport / L320
    Been a lurker here for some time, but fortunately this is the first assistance that I've needed thus far. I've had no problems even remotely related to what happened today, but got in the RR backed out of the driveway and no problems until I was pulling onto the major roadway. Once I pressed...
  10. Infamous black smoke under acceleration

    Range Rover Mark III / L322
    So after checking for all the usual splits in the boost hoses I finally found the problem a crack in the right-hand inlet manifold if anybody else is having this problem pressurize your inlet hoses from the intercooler and squirt some soapy water over the top of the heads to check for any...
  11. Touchy acceleration after startup

    Range Rover Sport / L320
    Just trying to see if this is normal, 13 rrs SC with 70k miles. I've owned it for almost 3 months. All service history up to date, dealer stated there is a minor rear main seal leak but no drips/leaking as far as I can tell last 500 miles or so and oil level is good. Other than that, clean bill...
  12. 2018 V8 Hesitation on Acceleration?

    Range Rover Mark IV / L405
    Just picked up my V8 today, loved everything about it so far, but I noticed when I step on the accelerator from a stop, there is a slight (but noticeable enough to be annoying) hesitation before the car gets moving. Yes I did turn off the engine auto-stop feature. Came from a 2012 RR V8 that...
  13. 1999 4.6L HSE Clunking noise upon acceleration

    Range Rover Mark II / P38
    Hi guys a few month ago I bought my RR with only 100k miles from its original owner. I love it btw. It was a leisure vehicle before but I drive it daily in a mountainous environment and it’s awesome. Lately though when I accelerate from a stop or up a hill I’m hearing and feeling a clunking...
  14. No acceleration until letting off gas

    Range Rover Sport / L320
    Sporty has developed another pesky fault. When accelerating the engine revs up without changing the speed. take your foot off the pedal and try again and the car then speeds up. No fault warnings come up Dougal
  15. TSB - LTB00305NAS3 - Vibration under Acceleration

    Range Rover Sport / L320
    On my recently purchased 2013 RRS HSE LUX I noticed that I was getting a consistent vibration right around 2700 rpm, regardless of which gear I was in. The vibration would appear at that RPM range and then disappear as I passed thru to higher RPM's...would also feel it again when descending...

  17. "Popping" noise under acceleration

    Range Rover Mark III / L322
    Hello i just solved an overcooling issue thanks to this forum and have another issue that ive been noticing with my 2006 range rover hse. From a stop or even under hard acceleration there is a "popping" noise coming from under the vehicle. At first I suspected it was a possible noisy strut from...
  18. Low speed hesitation with acceleration

    Range Rover Sport / L320
    For the past few weeks, I've been getting this new hesitation intermittently when traveling between 40-55mph and slightly accelerating in-gear. It's as if the truck is "bucking" (sometimes very aggressively), like the torque converter is not locking up appropriately. When I manually shift it to...
  19. Sluggish acceleration - gearbox?

    Range Rover Mark II / P38
    Hi Everyone 2001 P38 2.5 D HDE 130,000 miles. I've had a search of the forums but can't find anything specific to this. I've owned it for a couple of weeks now and as I'm getting used to it, it seems very sluggish to accelerate particularly up hill. The engine revs perfectly well and is, I'm...
  20. 95 County LWB Acceleration

    Range Rover Classic
    Hey gang, My 95 County LWB is hit or miss when it comes to acceleration. Just bought this rig a few months ago. She is a bit of a rust bucket, but she's my rust bucket. The frame is solid and my mechanic says the engine is in great shape. She has about 140k miles on her. I replaced the fuel...
