Hi there folks. I recently picked up a 2004 1.8 Tino, all seemed fine however first start of the morning is a bit of a stuggle - It fires up fine then after about 2 seconds gets very lumpy for maybe 5 - 10 seconds and then evens out, the rest of the day the car drives and starts great. This morning (it was below 0) it did the same but it put up more of a fight and stalled several times before it got up and running, and again it was fine afterwards. The engine management light isnt on. I have a full service history with car but it is due another one soon. I have read a lot about cam chains, I cant hear any rattles etc but is this the most likely culprit? Thanks
