Ok everyone,
So....the situation is like this....
When the engine is cold it starts but when I am driving it, on the first stop sign the engine dies (when in neutral)...if I am trying to start it ...it start on the 2'nd or 3'rd try.
Somethimes the check engine light is coming on.
I have done a check with a tester and the error is "overfuelling".
Now......I have changed all the spark plugs with original Denso plugs.....
For example: if I am turning the engine and let it warm up in the parking lot, it doesn't stall or stop at all.

What might be the cause of my problems?

Thanks

 

Retest the code and post it, it should be Pxxxx.
