I have a 1986.5 Supra non turbo. I changed plugs, wires, cap, rotor, O2 sensor, TPS, fuel filter, and put the timing to 10 degrees. I checked fuel pressure and it is at spec. I did a minor check for unplugged hoses causing vaccum leaks. I check my fuel pressure regulator and that was fine too. Im not sure what to check or replace next. Does anyone have any ideas???

How do you know it is running lean? Do you have a wideband?

I changed the fuel filter and ran injector cleaner threw the system the last 2 tanks of gas. I will chack more vaccum lines when i get a chance.
Can it be my fuel pump??? Do you think im getting pressure but not volume? I do sometimes have extended cranks
