It doesn't seem fried or damaged or anything else and its fault code didn't show up again.
I have checked everything I can find in the engine including:
Intake air temperature sensor
Coolant temperature sensor
Spark plugs and wires
Fuel pump and filters
But nothing. I mean there was no codes. Checked their resistance with dvm or their values and live dates on torque app.
The only thing that didn't work normally was o2 sensors that I changed them.
But one strange thing is my long fuel trim is the same as before o2 sensors change for both banks even after o2 sensors changed and reset ECU.
Just one thing changed in car behave
with my previous o2 sensors when I started engine from cold start sluggish acceleration was permanent unless I restart engine after restart engine, that sluggish acceleration was gone completely.
But now it's comes and goes even after restarting engine.
