Question about Vehicle Parts & Accessories
Multiple misfire detected dtc code p0300
Bad upstream O2 sensor on driver side. Low voltage to sensor sends lean code, which in turn sends more fuel to bank 1, resulting in multiple misfires. That being said, lets me say this as well, take it to a shop and have them look. So many other things can cause this problem from vacuum leaks to looking at it cross eyed. Hope this helps
