Hi, again, almost third time with this... well, thing
Vehicle: D2, Bosch engine, 4.0, XA chassis number, SALLTGM28XA901101
Problems before: Low power, condenser fan on whenever stationary (A/C was always off) and not such a smooth engine -but quite smooth-.
Repair: Dismantle MAF, change for another (2nd hand but assured to be OK), clean housing, assemble and test.
Test results: Engine not smooth at all, fluctuating idle, erratic and rough idle
Procedure: Cleal old MAF, assemble and test. REsults: Idle even worse after cleaning, rough running.
Testbook results:
P0150 and P0130- O2 sensors
P0171 Adaptative fuel mixture control Bank 1
P0174 Adaptative fuel mixture control Bank 2
too lean!
MAF error according to T4, I did not write it down correctly, if it was p0120, or p1202 or p0122.
Waiting forthe Actron scanner to reach me
After erasing faults, and performing a test drive:
-Erratic and very very very rough idle (from 750/1000 rpm to nearly stalling). After 5 minutes it stabilised, but accelerating hard in neutral and letting the gas pedal return to rest position it nearly stalled.
-So, now it is not lean, the A/C condensor fan does not run continuosly when stationary...
-Not usual exhaust smell (but not as rotting eggs yet).
-MAF? O2? injector? Pump? All them?
Any help (apart from setting my Rover on fire) would be greatly appreciated
Thank you very much and regards
