Since a couple of weeks a got the problem that the combustion stops for some seconds.
I do not call it ignition failure because my wideband is reading 17+ in that case until the engine runs normal again. If there would be only a failure in ignition the wideband should read fat mixture not lean as mentioned, right?
Before and after that behaviour everything runs fine. Lambda is jumping up and down - everthing alright.
Most of the time, that failure ends automatically within 1 or 2 seconds, if not it helps to push the pedal to the metal. It even occurs with MAF is disconnected and the ecu runs in limp mode.
Currently there is the C53 ECU in the car but it's the same with my evo8 ecu. I dont have another spare ecu to test, just a 2g N/A ecu - how far are the differences between evo8 and 2g FL?
Temp sensors look fine so far and no code saved in the ecu
Hope you have some more ideas - thanx
