Update:
Just came back from a test drive. I drove 5.3 miles with MAF and 4.3 miles with MAF disconnected. With the drive was a bit heavy and the car sound was uncomfortable while the drive without MAF was very light, responsive and the car sound was better. At the very last minutes it through P0100 and P0110.
After and before the drive I have take some readings. The resuls are as follows:
Key one but engine not started:
Absolute Throttle Position:= 7.8
Engine RPM:= 0
Timing Advance:= 63.5
Air flow Rate (MAF):= 0.00 g/s
Fuel System status:= Closed Loop
Short term Fuel Trim:=+25
Long term Fuel Trim:= -23.4
Intake Temperature:= 24 c
Coolant Temperature:= 23 c
02 Sensor1, Bank1:= 0.210
02 Sensor2, Bank 1:=0.295
Engine started before driving:
Absolute Throttle Position:= 7.8
Engine RPM:= 1080, 1320, 1240, 1400 it was up and down
Timing Advance:= 22.5 -16.5
Air flow Rate (MAF):= 12.42
Fuel System status:= Closed Loop
Short term Fuel Trim:=-25
Long term Fuel Trim:= -23.4
Intake Temperature:= 22 c
Coolant Temperature:= 38 c
02 Sensor1, Bank1:= 0.930
02 Sensor2, Bank 1:=0.765
After 5.3 miles drive
Absolute Throttle Position:= 7.8
Engine RPM:= 640
Timing Advance:= 14
Air flow Rate (MAF):= 1.54 g/s
Fuel System status:= Closed Loop
Short term Fuel Trim:= -1.6 - 0.8
Long term Fuel Trim:= -14.8
Intake Temperature:= 42 c
Coolant Temperature:= 94 c
02 Sensor1, Bank1:= 0.175 - 440
02 Sensor2, Bank 1:=0.830
Engine warm, without MAF before driving:
Absolute Throttle Position:= 7.8
Engine RPM:= 760
Timing Advance:= 14- 12.8
Air flow Rate (MAF):
Fuel System status:= Closed Loop
Short term Fuel Trim:=+7.8
Long term Fuel Trim:= -14.2
Intake Temperature:=
Coolant Temperature:= 84 c
02 Sensor1, Bank1:= 0.714
02 Sensor2, Bank 1:=0.645
After Driving without MAF for 4.3 miles
Absolute Throttle Position:= 7.8
Engine RPM:= 640
Timing Advance:= 14
Air flow Rate (MAF):=
Fuel System status:= Closed Loop
Short term Fuel Trim:=+5, -- +18 -- +14.2 -- +12
Long term Fuel Trim:= -14.8
Intake Temperature:= 24 c
Coolant Temperature:= 91 c
02 Sensor1, Bank1:= 0.740, 0.335, 0.115
02 Sensor2, Bank 1:=0.840
Frank and Japi, I hope can analyze this data and suggest something.
Regards
