Persistent misfire under load only
Combined short and long term fuel trim looks consistently positive at all RPMs tested, so it's running somewhat lean. Both banks are tracking the same, so the cause of the lean condition shouldn't be something bank/cylinder specific. Looks like at idle combined fuel trims are sitting at... -

Persistent misfire under load only
I just do my best to hold the accelerator steady for long enough to see the fuel trims get steady then keep it there for maybe 4-5 seconds - long enough to get it on the graph. For instance, if you increase to 1500 and see the fuel trims start to move, I’d try to keep it steady at 1500 long... -
Persistent misfire under load only
Are you still getting misfire code/live data only in one cylinder? I was thinking the misfire was causing the fuel trim code, but that time recording of fuel trims you posted in the other thread is showing identical behavior in both banks. Fairly lean most of the time with massive lean... -
Intermittent P0174-00 Code on '13 5.0L V8 w/ 130k Miles
@stone4567 Not likely a MAF if it’s affecting just one bank. Vacuum leaks also tend to affect both banks. If you can do it with your tool, check lambda and fuel trims to make sure the lean is just on one bank. If not, maybe try replacing the upstream o2 sensor on the bank with the code... -
PCV Valve, Diaphragm, Spring Replacement
The main thing that interferes with replacing the PCV on the supercharged models is the supercharger. It doesn’t interfere enough to make it worth removing it just for the PCV. I used Some string to keep the spring compressed while I got it into place, then pulled the string out - see post 13... -
2014 Land Rover LR4 SCV6 Hesitation/Shutter While Accelerating
You seem to have a code reader - can you check fuel trims? Also, you might take a look at your throttle body - see if there’s any gunk that might be causing the butterfly valve to hang up. -

Battery life
I believe there are low battery warnings for the tire pressure monitors and the key fob as well as for the aux/main batteries. I’m not sure what the particular messages are that you get with each type of warning. I seem to think the main battery warnings says something like low battery - start... -
Cylinder 8 Misfire
Spark plug, coil, fuel injector would all be cylinder specific failures. Any could give these codes and symptoms described. -
Fuel Related Issue at Start Up
I think I’d start by just replacing the HPFPs and see how it runs. Replacing the pumps looks to be a pretty easy job - not so much the timing on the pumps, but they might be fine. Vacuum pump is an easy replacement too. As for the alternator, you are aware that it’s a variable output... -
Where is my coolant going??
I thought dealers would have a qualified mechanic on staff, or at least on retainer. At any rate, a coolant system most often will only leak under pressure - just filling the reservoir will not tell you anything. And you don’t check for coolant leaks with a vacuum test. With the car... -
2015 LR4 Coolant Issue - Nothingburger or...
Coolant is pink or orange? If pink, someone has replaced it in the past. OEM coolant is orange. I don’t think an empty reservoir would cause me to pack it up and send it to the dealer. If you arrive at the dealer on a flatbed, I think they get dollar signs in their eyeballs. If the level... -
Auxiliary Battery
It’s the aux, and many of us don’t actually use it for anything but keeping the light off. i’ll take whatever ebay is selling over getting ripped off to the tune off 350 or 400 for the exide stateside. with the prices increasing, the other option (which i’ll do next time) is changing the...
