    Hello! So for the past couple of months I've been having issue with my car running lean (on both banks). I haven't yet done a smoke test but that is my next step and will be doing so in the next couple of days. The car runs perfectly fine and if not for the check engine light I wouldn't be...

    This is regarding a 2007 HSE with 190k miles. I'll start off by saying I have searched and read through every relevant post on this topic this website and google has to offer, so I'll ask a few different questions than what others have asked. I recently had my fuel pump fail (one day vehicle...

    Hello, I am doing some trouble shooting try to figure out why my bank 2 is running lean. So when I was replacing the spark plugs I look all over the fuel rail and can not find a Schrader valve ANYWHERE other than the AC system to check my fuel pressure . and do not see if on the code scanners I...

    Have a 2006 HSE. P0171 and P0174 showed up a about a month ago (at the same time). Got a smog need to pass in a couple weeks so have started to troubleshoot. After a bit of research, I think I've narrowed it to MAF and/or fuel supply. Here's why... 1) At IDLE long term fuel trims are around...

    System too lean, --Short Term Fuel Trim 1 is 0.0 --Long Term Fuel Trim 1 is 15.62 --Short Term Fuel Trim 2 is -.78 --Long TermFuel Trim 2 is 18.75 Im pretty sure those numbers aren't right and I'm using way too much fuel. I had it smoke tested and the shop told me I had a vacuum leak in my EVAP...

    I've been having ongoing problems for the last 2 years that I still haven't solved. Currently I'm trying to figure out why I'm getting lean codes on 1 and 2 banks. At idle the LTFT is 18 and STFT is 0. At 2500 RPM LT drops to 10.2 on the 7.6 while STFT stays at 0. Last week when I checked...

    Gotta a 2006 hse 4.4 jag and 135k replaced the alternator in it last weekend and after driving it around it got a new Engine light. System to lean bank1 and bank2. So my question is could this be from the software needing updated or just another sensor to replace?? any advice is always appreciated.

    I cleaned the MAF and then cleared the fault...fault will pop back up again...also as a result it has an idle issue where it will sometimes hunt for idle...i thought the MAF cleaning might have been the issue but I would have expected that it would have an effect on both banks... I did check...

    Hi, I bought a RRS 2008 a month ago knowing there's a orange suspension fault sign which reads 'Vehicle lean when cornering'. The guy said it started to show up after he changed the wheels to 22 inches with low profile tyres and that it not not a problem. In some youtube videos it is suggested...

    Getting pending codes P0174, P0171, P0130 & P0154. (Lean trim and O2 Sensor). Also ever since I've had the car it has misfired / vibrated at full throttle and high RPM. Using torque I can see the O2 sensors working fine, but the other day I managed to catch it misbehaving. Flooring it up a...

    to start, I have a 2006 L322 HSE 4.4L non-sc, bought in New York if that matters, but in Maryland now, 152,000 miles. P174 and P171 Lean codes on banks 1 & 2, I have a pretty good understand of what this is telling me, excessive UN-metered air and/or not as much fuel as requested, etc. I do...

    Hi all, Two times in the past few weeks, I've been driving the RRS when it seems to go a bit lopsided. Kind of like the entire car is leaning hard (in this case to the left). Handling is extremely poor and 'floaty' when this happens too. Pretty dangerous IMO. Seems to go away itself. The car...

    Happy holidays to you all! I have a 2006 L322. Not an SC. About a month ago had to replace the alternator and had the throttle body cleaned. At the time it was throwing the P - 0171/0174 codes. Mechanic cleaned the throttle body. I'm did notice the power increased a bit but my mileage dipped...

    Good day to all. As usual, every now and then when I go out in the morning, the Right side of my 2006 is leaning. The Rover folks at Al Faris here in Bahrain said I have to bring it in for a 'look-see'. - When I start the Rover, she balances out before I drive off. - Two days ago as I was...

    Hi everyone; I recently bought (3 months ago)a 2006 RR HSE. 67K at the time now 74K. It had a trans sleeve leak which splattered tranny fluid all over the bottom and a radiator leak(must be very small as I didn't notice it) as per my first diagnosis from the dealer. The used car place I...

    Hi all. I have a 2006 RR HSE. I have been experiencing a recurring PO171 code. I've had my RR mechanic keep it for the day and he had advised that the truck is fine. Possibly the "winter fuel" was the problem. I've been running super per his advice to see if the issue would resolve but after...

    Happy Holidays to all, I have a 2003 L322 and love it (of course.) I was wondering if any of my fellow owners have experienced excessive lean or body roll when going around corners at low speeds. I realize the vehicle is very heavy to begin with and all of that, but I was just wondering if any...
