I have a 07 IS250 with 95k miles. Yesterday I was at a red light. When the light turned green I pressed the gas and the Check VSC came on. The Trac light came on. And the CEL started blinking. The car started running like crap. Super slow and felt like it's bogging under acceleration but at idle it was smooth as normal. I drove it to autozone right away and got these 3 codes. When I was leaving to go back home. The car started normally and ran perfectly fine again . Since yesterday I out another 100 miles on it without any hiccups.


I also have a pretty consuming sound system. It pulls 1500watts rms. I know the alternator struggles to keep the revs steady at idle when the bass is hitting. I'm wondering if the RPMs dropped too low and it triggered the ECU to think there is something wrong with the car.
