this are the latest:
If I connect the lambda sensor after 2-3 sec the car idles erratically, also under load in the first or second gear it shakes and doesn't catch itself if I don't push a bit the accelerator!!
If I disconnect the lambda sensor, the engine gets more stable and idles more rhythmic, and under load it doesn't suffer that much at idle speed.
I still have the problem of turning on the engine when cooled down and it happened twice that it turned off itself after just turning on???
Engine still doesn't change it's mod after passing the 40*C, even I have changed the Temperature Sensor for Engine Management!?!?! (after this temperature the idle drops to normal 1000rpm)
Swapped the MAP sensor also with my spare one , but no change.
Yesterday I went to a garage that does computer diagnosis. We connected the car to the computer and from what I saw the program was Autodelta. With ignition on, the car communicates with the computer until a certain point and then disconnects it self
So I could not get a diagnose. Today I will try another garage, but I need to know if there is any trick to do that or it's just straight forward?
Any advice on this situation? Can just a bad oxygen sensor cause all this?
