Assalamualaikum.
I have a Toyota Corolla 1990 AE(91) AEPEK powered by a JDM Stock 5AFE along with AT.
In recent days the Octane consumption has gone as high as 4 KM/L!
I have fixed following:
Injector replacement
Oxygen sensor wiring fixed
RPM adjusted
Butterfly cleaned
VSVs replaced
Air filter changed
Everything that came easy.
Meanwhile, I have connected TE1 and E1 on diagnostic ports and found OBD 1 code of 51. But my AC switch, PNP transmission switches and Accelerator cable is fine.
That left me only with checking/fixing/replacing my TPS and ECU. My garrage mechanics are locally skilled but know very little theory about all these. At least less theories than me.
I'm going through a tough time to figure this anymore.
What should I do now please?
Thanks a lot in advance.
