mine sadly is doing something similiar, 118000km on the clock.... I've only had the car for about 10 days though
Check engine light comes on randomly and will stay on for a bit, maybe go away but generally stays. Yesterday though, there was a bit of shaky idling and quite a bit of misfire too
I'm assuming it's the coilpacks, i've literally checked everything else and done my homework. Just have to wait till I can afford another $600 on coilpacks, boo
