Fuel trim question: I’ve got a 97 1FZFE. Set my Ultra Gauge to monitor fuel trims. Long term fuel trim is ALWAYS +8 to +11%. Short term fuel trim is always +/-5%, and typically less than +/-3%. If I had a vacuum issue, I’d suspect the LTFT would drop significantly when I hit the gas pedal hard, but it doesn’t really change. I can’t detect a vacuum leak and pretty much everything is new or rebuilt, except injectors and knock sensors. Injectors were rebuilt and flow tested by Witchhunter. Fuel pump, strainer, fuel filter, fuel pressure regulator, fuel pump relay, and igniter are all new. Any ideas of where to look?
