Hi was just wondering if someone could help me. Been driving the car for a while now. Rb24det 35/40 been awsome. But tonight was giving ir a bit the tempreture has dropped quire a bit and it would boost fine in 3rd up until 6000 rpm the would just feel like ita atopped pulling. And the i tryed ir again the same thing happened tryed in again and put my foot down in 3rd and just struggled like all noise no go and the engine light came on and knock reading went to 94 would this juat be due to the rempreture change and it being run on e85. Was just going to rake it back to my tuner just wanted to see if anyone has had this problem before or may kno what causes it

Thanx

Pls fix your keyboard it seems the r and t have swapped and its spelt "tried" there is no y...

So hard to read...

Bad spark?

Need more specs and info

And putting it in the right section would help, this would be better in forced induction

Sounds like your tuna hasn't compensated for different IATs and I'm assuming you're not running an AFM too.

Do you have a wideband AFR on the car? I'm guessing when it's colder your car is leaning out.

      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.
