    06 LX470 Towing Update

    All, I wanted to update the thread here. I've now replaced the CATS with the DEC option. This cleared the P0420 code, but the P0430 was still popping up periodically (cold start). I noticed that my truck would kinda stumble at idle and had choppy throttle response in neutral, just revving it...

    Failing Fuel Pump Symptoms? Edit: Now With Data

    My truck has a bit of a stumble at idle and a choppy throttle response when revving in neutral. I'm not seeing a noticeable drop in vacuum when holding steady at 3000 rpm relative to idle vaccine pressure.

    Failing Fuel Pump Symptoms? Edit: Now With Data

    I just replaced mine with OEM at 225k 06 LX after having fuel vapor lock and stalling. I have the CEL still on with the P0420 P0430 CAT codes. The exhaust shop here says the fuel additives are clogging up the CATs

    06 LX470 Towing Update

    Yup, replaced all O2 sensors. I've put 2 tanks through since that swap and CEL keeps coming up. The 06-07 has VVT engine and it has a different CAT setup.

    Am I an idiot for selling my 100 for a new defender?

    You might compare the number of TSBs between the two just for kicks.

    06 LX470 Towing Update

    ^^ thanks for the posts here. I did get myself an OBD2 reader and have been resetting the CEL and testing. Unfortunately the P0420 P0430 codes keep coming up. I will try the premium fuel and report back, but I believe the CAT on the passenger side is blocked up. The 100 series can tow. Some...

    Strange clunk and window movement in both front LX470 power windows

    I think there are a few bolts with slots for adjustment forward and aft. They become loose over time and the windows have some movement. I did tighten them up on my 02LX, but my windows are little loose on the 06LX now. It requires removing the door panels and the vapor barrier, then 10mm socket...

    Troubleshooting Overheating - What Next?

    I saw a video on how to check for exhaust gasses in the coolant. You might see if you have a head gasket leaking. I have experienced the burp issue in other land cruisers. It ran fine for months around town after radiator work, then on a long highway run the bubbles made their way past the...

    06 LX470 Towing Update

    Update on this: I've been driving around and hoping this would clear up on its own, but that's not happening. So I stopped in at one of the aftermarket muffler shops in town and they confirmed that the passenger side CAT is running way hot. So I watched some "Clean your CAT" videos on YouTube...

    06 LX470 Towing Update

    I did, but I will check that again. I know I'm pretty anal about checking 3x, so I should probably check again Lol

    06 LX470 Towing Update

    Well a few months ago (March) I did clean the MAF and TB. I also changed the air filter, which I checked this morning and it was relatively clean. I was pretty gentle with that MAF when cleaning it.

    06 LX470 Towing Update

    ^^^ I've been driving like 3-4 hours a day this past week and have filled up 2x now since the towing events etc. I am filling up with mid grade 89 as I normally do. I am getting better fuel mileage. I'm averaging like 15 mpg with some stop and go and 45mph back road driving in the countryside.
