Hello everybody,
I have a 2007 Honda Accord 2.4 and the problem is that my short term fuel trim is negative (-18%) causing my car to run rich.
If I switch off the engine (cold or warm) I have to wait a few minute before I can restart.
The idle is fine until the engine gets warm and the car will eventually stalls if I press gas unless I create a vaccum leak (Disconnecting PCV hose for example).
Fuel pump, fuel filter, sparks plugs, ignition coils, injectors, crankshaft sensor,...they have all been replaced recently.
I suspect a bad O2 sensor but I have no check engine light.
Any help would be appreciated.
