Hy guys never thought I'd be one of those people that ask questions on a forum but I'm seriously out of ideas.

 

 

car - ke70

 

engine - jdm bigport 4age

 

problem- wont rev

 

ok so Ive just bought a 4age ke70 from a friend that just seems to not run right, it'll idle just fine but as soon as you blip the throttle it does and starts to stall like its sucking in too much air and not supplying the fuel for it.

but if you disconnect any injector and rev it, then it revs fine just on 3 cylinders. The moment you plug the injector back in it doesn't rev at all once again.

If you hold the throttle open the minimalist amount you can allow it to slowly pick up to 6000rpm but the moment you go any further throttle it just dies and goes back down

 

So far I've changed fuel pumps and upgraded the fuel lines to 8mm

different injectors

Fuel regulator

about 5 maf sensors

Igniter (changed to a camry one)

tps

Coil

cleaned all earths and added in some more

3 different ecus

changed timing numerous times (seems to slightly prefer to be at 25 degrees btdc) also was set properly with lining up the cams and crank.

looked everywhere for air leaks

re-sealed the iac (blocked off)

Also done test from the ecu to to most the wiring in the engine bay and can fault it.

doesn't matter if running temp or not just does it all the time

 

 

I've looked everywhere on the forums and I couldn't find anything (with the actual end result at least)

 

also my friend said it was running fine in a defected shell then he put it into another shell and that's when it began

 

Plz someone halp

25deg btdc at idel?

 

Seems far too much.
