OK. At low throttle or idle the car shudders.
Pulling the codes shows radom mis-firing. During acceleration, the cars power is unpredictable.
Since it's been going on for so long, I can also say that it occurs at outside temperatures above 28 degree Celcius. In cooler weather the car is smooth. The dealership cleaned the throttle plate one time and it cleared up for about 1/2 a day. They're replaced coil packs and injectors.
They measured the voltage to the injectors and the ECM is trying to compensate for some problem with over-voltage readings. Any suggestions or similar experience is WAYYY appreciated.
Thanks in advance for any contributions to this post.
