Anyone knows what these fault codes could be
P0606 ecu microprocessor fault
P1177 mixture correction
P1178 mixture strength
After only 20 km driving the mil goes on on most of the time i have these 3 fault codes, the P0606 is not always there.
Engine doesn't have the good performance, I did a measurement on my test bench, only 105 hp on the engine
These fault codes are allready a long time there.
A few months back the engine failed, 1 piston melted, scracthed the liner, strange thing was that the inlet valve was looking as clean as new, the other 3 weren't, so it looks like the injector maybe kepped injecting, therefore a clean inlet valve and maybe the melted piston.
We repaired the liner, and fitted a new piston , engine is back running but as I said these fault codes and not much hp.
The injector of that cylinder I allready replaced when I repaired the engine.
We have this car allready 5 years I think, but never this car went so good as 150 hp, so i think there is something wrong for a long time.
Maybe some one knows or had this problem also.
