Today I cleaned throttle body and MAF sensors, then I did all the procedures... ECU reset, idle learning, throttle body calibration etc looks a little bit better, so let's say car is not "jerking" and not shaking, but
But, the problem is:
If I disconnect the battery for a while, then car is driving like +100 HP, even on NORMAL the performance and throttle response is crazy....much much better than on SPORT, like 350 HP car...
but after 200-300 km (100-200 miles) - back to normall performance, even on SPORT
no CE codes (I checked with Car Scanner).
spark plugs are new, engine oils, filters - everything is new
I'm going to replace the power train fluids as well in next few weeks. - but might this be a problem? ECU is going to "safe mode" or something like this? Is it possible to check this with Consul?
