For now I only have some answers , I don’t have any values HC,CO or O2 , at inspection they only said have to much emissions , last year I lost 4 times and at last time i have the help from the inspector (I believe he help-me).
In February I have the anual inspection , and I know something is wrong because the lamba correction the value is arround 72 and must be 1 because I have measured in other same model car.
I have readed your last post and I have changed the coils but same result.
Three day ago I have replaced the switch fan sensor.
The temperature (blue sensor) is working because using IAW software I could measure the temperature.
In this car I have previously replaced all injector body , replaced ECU , replaced Lambda (removed from another working car) replaced the canister and respective valve , replaced the MAP sensor , and same problem.
Today based in your last message I do the mesure and apparently the conclusion is , with the motor cold , I start engine and the lambda shows open , and when temperature is arround 45C lambda shows close , could be coincidence because I have this test only one time , but , during the period the lambda is open , the lambda correction value is the desired , the 1. Tomorrow with engine cold I repeat again this procedure to determine if was coincidence or not.
One last procedure I have done based one factory manual is the readaptation modules , I have disconnected the blue temperature sensor, MAP sensor and trotle potentiometer in injection body and start running (have done 2km) when arrived , disconnect the battery and past 5 minutes reconnect itens previously disconnected , reconnect battery and put motor working , when hot the fan arm , i have done 3/4km km. But this don’t solve my problem.
I fact i don’t know more what to do. The strange is the car works fine , apparently there is no problem. Start well , run well.
About sparks color , if i run the color is normal , but if only put motor working for a long period with moisture rich probably the sparks goes black.
This car I think don’t have the thermostat.
