nah not yet but the fuel pressure was all good when we tested it I have put in an safc2 so I can watch for knock... it just hard to look at cause it doent always happen just every now and then! or it will happen like five times then clear up?

the dyno sheet would show if it was actually leaning out, otherwise you are guessing. if it does show this then the things to check have already been mentioned, otherwise get someone to look at it before you break it.

yeah I would guess a fuel pressure problem - put a gauge on it and make sure you are not short of flow up high. dying fuel pump, fuel pump wiring, blocked filter etc etc etc. some of the jap ecus are a bit leaner than we like but they should not be causing it to ping all the time

Check your TPS.

If it isn't working properly, then you will lose the throttle enrichment, hence, a lean out when you first step on it.

Also, earth the fuel pump as mentioned.

Throw some new plugs in it gapped at 0.8mm

Clamp the return from the fuel rail, that will tell you if the pump can't keep up or the fpr is screwed.

I had the exact same symptoms, mine was a torn diaphram in the fpr so it was leaning it off all the time, as well as a fuel pump with ~10v at it when at full throttle.

    • 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.
