Gents, here is my story.
My problem is based on unexpected “car hesitates to move when the gas pedal is pressed”.
Car – Pajero 3.2DiD 118kW V98W (180k km mileage)
It happened few times (past 2 weeks) during these situations:
– car stopped at lights (to be sure – no Neutral used)
– accelerator pedals pushed, engine RPMs increase to expected range (visually and noisy), no wrong sound
– but car really hesitates to move, speed about max. 5km/h
– several attempts to push the acc. pedal, no change the car speed still like turtle
– it spends 5-10sec and then (magic) car is back into normal operation.
No engine light, no ECU Fault code found.
Till today I found a Fault code: U1120 (by Torque Pro App). I found tons of U1120 dramatic stories, but just this one is logical:
U: OBD-II Diagnostic Network (U) Trouble Code For Engine
1: Fuel And Air Metering
1: Fuel Rail/System Pressure - Too High
2: Turbocharger Boost Sensor A Circuit Low
0: Shift Solenoid E Performance or Stuck Off
Need to measure.
Diagnostic of all measured values (till now) are in normal levels, but just during the normal car operation. Can send if it helps you. Because this situation (car hesitates to move) occurred randomly, no way to measure all the values during whole time of "normal" car operation.
Sometimes (randomly) I feel a delayed reaction of the engine from the acc. pedal. But still no Fault code or the Engine light.
Also checked EGR. No problem found.
But there is still “empty” fault code pool in the ECU.
How is your point?
Thanks.
