Misfire on single cylinder with no check engine light
Hello all. Just wanted to see if I can get some help as I've been stressing my self out trying to find what's wrong with my car.. I have a
2017 supercharged brz. Car had 37k miles. I've been getting a single misfire on cylinder 3 but the misfire is only happening at cold start/idle. Once I drive my car and put it back to idle my misfire is gone. I'm not getting no check engine light so I can't go based off any code.. I've swapped out coil pack, spark plug and even threw in new injectors. Once My car is in drive the misfire seems to go away as well. I'm including 2 logs one at idle and one on normal driving. If anyone can help I would really appreciate it. |

how do you know you are having a misfire? What injectors did you replace?(PI, DI or Both?). Being modified I would look at the tune first.

My na FRS runs a little rough on cold start, no cel. I've been told it's because I have a lightweight flywheel. Not sure if it's true. Just repeating rumors.
