159 2.2 JTS Misfiring and Check Engine Light
My 06 159 2.2 JTS has over 200,000km and now has a Check Engine Light on. From cold, it misfires until revved for a few seconds. It also sounds rough when the timing changes (1500 - 2000 rpm). No loss of power and seems to drive well once going. Local independent says it's likely a head-gasket leaking coolant into cylinders (he can see misfires on cylinders 2 and 3 on startup). The 'rough sound' at timing change happened about 6 months ago too and timing chain was replaced which solved it for a while but it's back.
