    Persistent misfire under load only

    Ok, so if I’m interpreting the information correctly I should have a vaccum leak because short term fuel trims drop significantly at 2500 RPM?

    Anyone know this part number?

    Discovered today why I’ve been losing a little bit of coolant. Seems like the bleeder cap on the top of my front cross over pipe is leaking. Does anyone know the part number for this, I can’t seem to find it?

    Here are the fuel trims. I took 2 screen shots at 1500 ish rpms because the rpms like to fluctuate at that rev range.

    2012 lr4 5.0 misfires and p0003 fuel volume regulator

    If the pumps are testing good, could point to a wiring/electical issue. How’s your voltage and how old is your battery

    Persistent misfire under load only

    I’ll get the car warmed up and take some logs. Any specific RPMs you want me to hold it at? I think someone said 1500 but when I try to hold it there the rpms like to fluctuate 100-200 rpms up and down. I could be wrong but wouldn’t it mean that both O2 sensors are bad since both banks read...

    Persistent misfire under load only

    At idle when these cars are warmed up they I believe the general rule of thumb is long term-short term=<+/-10%. As you can see mine are way past that point.

    Persistent misfire under load only

    Ok, updated the tool and can see everything now. The car is running rich… super rich. The first screen shot is before I cleared the fuel adaptions. The second is after I cleared them and took a short drive around the block. Additionally, I pulled up some voltages that seem a bit high but could...

    Persistent misfire under load only

    This is what I’m aiming on. I emailed Gap, they just sent me an update for the G3. Really hoping that I gain the ability to reset fuel adaptions because I think this could possibly be the issue. Probably a long shot though. I’ll keep you guys posted, I’ll be back with the car on Saturday.

    Persistent misfire under load only

    the tool won’t even go as far as giving me a misfire counter for live data… I’m going to purchase this new tool to properly diagnose. In the meantime, does anyone have any ideas why fixing a small leak in the PCV system would make a misfire/stutter in rpms so much worse?

    2016 LR4 Landmark SCV6 Engine Failure at 65k. WWYD?

    When you do this make sure the hood is open.

    What does the codes mean vs gap. If I got a code for misfire on cylinder 4 on the gap tool would that mean drivers side middle cylinder or drivers side front cylinder? I wouldn’t have a problem pulling another injector if it is the middle cylinder

    Persistent misfire under load only

    Is the SSD cheaper than the upgrade?? I’m just not trying to spend more money than I have to on a tool that realistically I would only be using on one car. I can’t get the money back that I already spent on the gap tool.

    Persistent misfire under load only

    I read the forum and I did the thing where you unplug the coil and see what it labels each cylinder. When I did it I unplugged cylinder 2 on the V6 layout and it called out cylinder 2 when I put the ignition on engine off. Did the same for cylinder 3 and it labeled it cylinder 3. Do you think...

    Persistent misfire under load only

    It’s because this is discovery 5 and I’m using a gap tool G3 which doesn’t have the full reading capabilities, I know it’s weird but the information it provides is accurate, the actually issue is that it doesn’t provide much information. What I mean by that is I don’t have access to all of the...

    SCV6 Hey all, Just have some more updates: So I was snooping around last night and found that the PCV system had a leak. The pipe that comes off of the intake duct and goes into the PCV system for bank 2 was cracked where the male side of the pipe fused to the intake duct. I sealed it shut...

    Persistent misfire under load only

    Update: no difference. I replaced plugs coils and injectors, nothing. Side note: I noticed that if I put the car in park and put my foot on the throttle in a fixed position rather than the rpms going to a certain speed and remaining there they will actually fluctuate about 300-500 rpms. When I...

    Persistent misfire under load only

    Update: I am a huge *****. I’ve been doing research on the issue trying to make sense out of everything before pulling the trigger to upgrade my IIDtool. While doing research I had an idea to check if I had any lean/ricg codes stored in the PCM when I took a screenshot of the misfire code last...

    Persistent misfire under load only

    I would’ve provided this data already but unfortunately the G3 gap tool shows limited live values on the D5. I’m going to have ti talk to the Gap team about upgrading, I’d really like to get the discounted trade in price for the G4 tool. I believe the discounted price is around $170 while the...

    I know, which is why I did coils plugs and injectirs on cylinder 3 on the V8 pattern and the V6 pattern no difference.

    Persistent misfire under load only

    Hey all, Getting a lot of similar symptoms with a D5 which has the SCV6. The misfire only happens under load and is mostly noticeable when the car is cold (oil is below 180) when first starting to drive. The misfire only happens around 2500-4500 RPM when under load in any gear from 4th to 6th...

    I did mine on the inside of the door cards because they would rattle like crazy with my music turned up.

    Coolant Temps

    Good to know, thank you @Rover Range . I’m guessing it runs higher temps because of the colder intercooled air? Does the SCV8 run this way as well?

    Coolant Temps

    did you ever figure this out? I’ve got a 2017 Discovery with the SCV6 that I just replaced an injector on. While test driving it I was running temps and started to notice that the coolant temp climbs to pretty high temperatures. Was climbing up a hill for a couple of minutes and the temp touched...

    Diagnostic Trouble Code: B1A85-96 (28)

    I’ve had this fault for years, both codes and everything. I’ve never had an issue or noticed anything wrong, everything works as it should. If I didn’t see the code I would have no idea it existed.

    150k miles, time for differential and transfer case fluids

    what fluids have you found that match the specifications that aren't going to drain my wallet? I saw Atlantic British had a rock oil Gearaxl https://www.roverparts.com/differentials/gearbox-oil/IYK500010/ not sure if this meets specification for the transfer case? would their rear differential...
