Good morning all
The above car came in last December with EWL on, 17545/P1137 LTFT Trim too rich stored. Monitored live data & carried out emission test all appeared good.
On road test car discovered engine running cool.
Replaced faulty thermostat now runs correct temperature.
Same fault returned ten days later, again everything appeared ok so renewed coolant sensor.
This code keeps returning every 7-10 days with no other symptoms.
I have read the excellent threads on fuel trim, what am I missing ????
Sorry to go on a bit & thanks for reading
Glyn
