Firing on 3

A car day with my wee helper. After replacing a rear shock on the polo, took the 9-3 out with Ems. Sun came out, so decided to get a bit wind blown. Car was misfiring wildly on major acceleration, so we pulled over and had a look. Coil packs needing changed out - can’t handle the increased power. Despite the stuttering and slight judders, I think Ems loves that car.
