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
