It is in open loop SD so the maf is not factored in. I have checked for vacuum leaks but have not found one yet. Might bring the smoke machine home from work tomorrow to check it. At this point I am almost ready to trailer it to a good performance shop. I know that is said coming from a L1 certified ASE mechanic who is also a Toyota Master Diagnostics Technician. But I am stumped at this point and am out of ideas. Let me make a list of what I have checked and tried.
1. All grounds are good: PCM, Battery to engine and body, both on back of the motor, and the one by the power steering pump.
2. Fuel pressure is 53psi with vacuum and 60psi without.
3. Have tried every combination of injector data from HPT Repository that has 42lb to 60lb injectors. Seriously I have flashed my truck over 100 times. Ran fine on previous data till I parked it for several hours.
4. New O2's went in with the motor 200mi and 2 weeks ago.
5. All injectors and coils are firing checked by way of cylinder drop test.
6. All input sensors are giving the HPT Scanner good readings.
7. Not a vacuum leak, smoked the intake system.
8. Not the injectors installed new ones from FIC with correct data.
