I need help. I have a 97 camry. That plain shuts off at 3200 rpm or below 1200 rpm. Have to hold throttle between there to keep it running. Already replaced idle air control valve, and cleaned throttle body. Replaced fuel in tank because 3 year old gas. And replaced injectors due to injector balance test failed . One injector was dumping fuel and not holding. Fuel pressure is good at 50 psi. Regulator is part of fuel pump in tank. Scoped tps, maf, 02 sensors all looks okay. blocked off egr to see if there was a change there isnt. verified all coils firing. Timing belt is new and in time. Spark plugs replaced. Compression test is good and leak down test is good on all cylinders. Im running out of ideas i dont know what it can be.
