Hello,

reset the learning values in the engine ecu and test it again, If all is okay maybe it have bad fuel inside

Thank You, I have already found the solution, the cause was prosaic - spark plugs, the wrong spark plugs were simply ordered for this engine.


But I have one more problem, I cannot connect with the engine controller using lexia, it connects with other modules without a problem, but with delphi it connects with every module, to test this I connected lexia to another car with an identical configuration, make, model, year of production and I also cannot connect only with lexia and only with the engine controller.

try to connect when motor on idle, or another version of Lexia
