possible trigger reading/error ej205 USDM wrx ver.7 plug in G4

Recommended Posts

hello, sorry for my bad english!

Yesterday we set the car on the dyno and noticed a strange behavior. in the range of 6000-6500 RPM engine car rides badly with jerk's. At this point value of the trigger error counter increases. Above and below the 6000-6500 RPM of the engine is running perfectly. Also in this zone, the car tends to lean sharply mixture, possibly due to misfire. I wrote a log,  ( in attachment )

Why is this possible? Generator, poor grounding, detonation, a defective sensor? We are grateful for your reply!
