Anyone know what this night be? Misfire?
Well idk what happened exactly but a few steps id take to help figure it out is this
1. Check ur tuner for any codes
2. Check ur intake system if there is a leak it can mess things up so check the MAF Sensor, and any of the connection points
3. Make sure its not bad gas
4. Check ur plugs and coil packs one of the COP could have gone bad. It rarely happens but it happens sometimes
