Just had car fully checked and everything seems fine from spark to fuel.

Until I checked to see my power fc inside and looked like this.

Car is still hunting bad on idle and wont drive past 2500/3000rpm and runs pretty horrible with no power.

Most likely this is the cause as have changed just about everything.

Would anyone let me borrow for 5 minutes there power fc to test so I no for sure it is the problem, but I guess it still needs replacing by the looks of it lol

What do you guys think.

Holy Shit, I'm suprised it's driveable at all

Yes I'd say that is your problem. Do you recall anything that may have done this (bridging plugs etc)? Probably just the Power FC crying enough over age but if it could be something that has caused it on your car, then you need to fix that before replacing the ECU or it will happen again

I bought it few years ago and it had water in it and didn't no much then and as when I hooked it up it made a choooof sound and smoke came out and didn't make much of it back then so really forgot about it.

It ran ok till now but I just bought a adaptronic ecu all hooked up with a tune in it similar to my set up and still done it and I found the problem injector 5.

As soon as I disconnect it does nothing in engine sound at this point as all other injectors are fine as they change the engine sound when I disconnect the plugs from them,but sometimes it might start working but for now that's it.

Must be cause I ran the injectors real hard on e85 pushing 330rkw and think there 550cc.

Either blocked or leaking injector 5 but there's really nothing more but that as I changed every thing and this problem got worse after e85.

Still needed to change the ecu no matter Wat the outcome was as that PFC was ftt up and guy ripped me off which was not nice for $900

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
