  4. Engine Misfire on 2005 L322

    Range Rover Mark III / L322
    Greetings, I just bought a non-running 2005 L322 (BMW engine) to rebuild/fix up. The engine starts but misfires badly (some backfire) and dies after running 10-30 seconds. IIDTool came up with Camshaft position sensor circuit bank.2 and misfires on cylinders 5,6,7,8 (makes sense, driver side...

    The truck sat for a over a year before I bought it. I replaced the BECM, ECU and instrument cluster and it started to run. I replaced the leaking heater core o-rings (the carpet on the right hand side was soaked). I replaced the spark plugs and did a compression check. a couple of cylinders...
  6. misfire sometimes 2010 Range Rover Vogue 4.4 TD V8

    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 problem . regards Andy
  7. Misfire solved!!

    Range Rover Mark II / P38
    Well almost. I've finally got to the root of the problem I've been having ongoing for months! At first I was under the impression I had a failed lifter, but when i got the valley gasket or of the way, one of my exhaust cams was completely round. New camshaft then, assuming might as well put...
  8. P0021 and Misfire on #7

    Range Rover Mark III / L322
    In my never ending timing chain guide project, I finally reassembled and started her up. Idled great. Got the coolant bleed and looked like we were good to go...until I got a P0021 and a misfire code #7. It idles well and smooth, but try and drive it and I got the codes. Looks like timing...
  9. 2004 L322 misfire codes P1300 and P0305-308

    Range Rover Mark III / L322
    My 2004 L322 was running and sounding fine until I tried to start it yesterday morning. Really rough idle and engine light. Pulled the codes with my generic reader and it showed P1300, P0305-P0308 (a generic misfire and misfires on all of Bank 2). I should have used my RSW reader, but it is...
  10. Issues Passing SMOG

    Range Rover Classic
    Hi all, I've got an interesting issue and wanted to get a second opinion on something. So first off, I have a 1991 RRC that I got from a coworker. He bought it in 2016 and left it in our company parking lot for 2 years, where it just sat until I got the keys and title a couple months ago. I've...
  11. ongoing intermittent misfire

    Range Rover Mark II / P38
    Hi I've had this problem for quite a while now, ever since I replaced the head gaskets, but I've been busy with work and just not had the time to spend on it. I've finally 'given in' and let the local garage take a look and see what he can find out. He's come back to me and said he's put an...
  12. 2010 Misfire codes. Seeems to be resolved

    Range Rover Mark III / L322
    I have a new to me 2010 HSE with 124k miles. I first got a code for a misfire at cylinder 4. I reset it then came back with a few cylinders. Then the CEL went off on its own. Once again it showed up in multiple cylinders. I read about the BG44k cleaner as suggested by Land Rover. I ordered a can...
  13. Live Data - Misfire M62

    Range Rover Mark III / L322
    Hi All, Can anybody see any faults in the data that would cause my 2004 4.4 to misfire but only when up to temperature? It drives fine first thing in the morning but after about 10 or 15 minutes, a misfire develops. I ran a dose of cataclean through the system but it has not helped. Are the...

  15. misfire woes

    Range Rover Mark II / P38
    Hi Since I changed the head gaskets, I've been getting multiple misfires on both LPG and petrol. (both perfect prior to head gasket change) I'm getting P1319 which is fuel related, but I think this is a red herring. The reason being, when I put a timing light on a HT lead, I can see misfires...
  16. Misfire Under Load

    Range Rover Classic
    Been chasing ignition issues on my 95 SWB. Had a crank no start situation that was the result of a faulty distributor rotor. Replaced with genuine LR part and it ran great for about an hour this after noon then started misfiring. If I let the truck sit for a few minutes turned off it would run...
  17. Check engine light on, rough idle, misfire #7

    Range Rover Mark II / P38
    I'm getting a misfire on the #7 cylinder of my '01 4.6. Mechanic did a quick check on it today and plug is clean (relatively new plugs and wires). So he then did a pressure test and said pressure is low in the cylinder. Reads 100 psi, (when I guess it's supposed to be around 150psi(?)). He...
