Perhaps the wiring has broken. Seen that before (wiring is too tight and snaps just near the sensor)

The knock sensor is a pita to get to, and the coaxial from the sensor is incorporated into the loom for the injectors. I should have a spare for that somewhere too if you want to change them both.

Have you checked the ecu plug inst loose or corroded?

Thanks for the responses.

Symptoms. Runs OK. Significantly down on power, comes on to boost later and not as strongly. Uses about 3L per 100km more with gently driving. Runs even more ridiculously rich while warming up.

I assume is running rich and retarded. (Who does that describe?)

Mechanic had analyser attached and it showed knock sensor faulty. I asked if it could read same if just a problem with the connector. He said the software could distinguish between faulty sensor and faulty connection.

I was quite suprised that the stagea was in his device. That said, he tells me he paid a few grand for the last SW upgrade to it alone.

Will double check connections on the week end but he isn't known for BS when not sure what is going on. Sounds like I might get him to put it in so he can do the swearing and loose skin but will have a look at where it is first.

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
