Hi, I have a Fiat Brava 1.2 engine, my car started to feel like it lacks power when accelerating and maybe also a higher consumption. I received a error 3 times , the error disappears after I turn of the engine and let the car stay off for some time , the error appears rarely (like 1 time at 2 months randomly) when it appears the engine has no power and the accerleration it's very delayed.
When there's no error light the car seems to work almost fine except the lack of power when accelerating.
There's no errors in Multiscan.
Things that I tried/changed:
-Lambda sensor
-Ignition coils
-Spark plugs
-Distribuitor cap

So it is an older version of the engine with more basic electronics ? That means not much diagnostic information but also less things to go wrong or disturb the engine.

With an older car you need to check for damaged wiring or hoses, air leaks etc (also in the exhaust near to the lambda) can confuse the fuel mixture and make the car run rich.

Do a good service on the cooling system - flush everything, check / change thermostat and change temperature sensor.

Also consider maybe blocked or failing fuel injectors ? Or blocked / failed Cat ?
