Exhaust Pop
I'm noticing an persistant issue with my automatic FR-S. This happens mostly when the engine is cold and set in sport. I hit that accelerator from stopped or rolling start and in between the shift from 1st to second there is often a exhaust pop noise, similar to but not as loud as a back fire. The shift is also very rough comparable to other shifts from 2nd to 3rd etc.
Has anyone else noticed anything similar?
Car is stock.
