It's the resistor pack for your injectors. Its there to change from high impedence to low impedence. If any wires are shaved, try repairing it. This unit can be removed for repair, but for now lets try fixing the problem you have now.

Check No.1 coil very carfully - something might be there

Photo's are there now.........

No problem, thats one of the reasons why we are all here, share, talk & help.

Your plugs must be gapped down, its not hard it you have a filler guage. I can guide you through it if you like.

been reading a few threads, and i found this one:

almost the exact semptoms. i realy hope its not a gasket

OK, I have read this post. This is true - if your car runs very rich, it will misfire but if you replace the spark plugs - as I have suggested - it will run fine for a while until it misfires again but we at least know where to start looking.

In any problem solving, process of elimination is your friend. We have to check what works to find out what does not.

P.S. Gapping plugs with even a good Mallet, hammer, brick is a health hazard....... only qualified professional machanical engineer technican should use these devices.

is this what your talking about? coz i found one! loool

Thats the one!!!! Even people like you and me can use this, no qualificians necessary.

1. find 0.6 filler guage.

2. on something soild like a metal bench, tap the spark plug with just enough force to shorten the gap.

3. Contine doing this & check with the filler guage.

4. If you over do it just use the filler guage or something else to very slightly open it up.

5. The filler guage should slide in without moving about or move very slightly.

In your situation because you have 1.1mm gapped plugs, measure from the tip of the spark plugs, they have to be bent a far bit - this is why the BKR6E has a factory setting of 0.8mm gap, better and easier to gap to .6 or .7. Another thing, the 6 is a hotter plug, does not foul as easy as the 7 plug range.

0.6 is probably a touch to small, the gaps on modded GTR's i've heard used are usually 0.65mm-0.8mm... Not sure about 0.6mm but can't imagine it making a huge difference either way - why not aim for the middle of that - say 0.7mm?

oops sorry, I meant 0.7 as your other spark plugs were gaped at these & 0.7 is a good gap to keep. Mine are at 0.6 but I have alot more boost & fuel to iginite.

Sorry about the confusion

      Unpeeling the Orange

      By MBS206 · Posted

      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.
