Hi all first time post.
My wife has a 04 astra coupe turbo that has two issues.
after the engine warms up and say you stop to get fuel you cannot restart the car. it turns over fine it just wont fire into action. let it cool for an hour and it starts first time and your away.
also it has just started to cut out when idling in traffic it did this the first time the other day and because it wont warm start then your in a heap of hurt untill it cools after an hour.
SO, im thinking crankshaft position sensor is the first thing to replace, what do you guys think.
this may be related but idle is smooth then just suddenly drops to almost stall, but then idles fine again for say 10mins, then it again drops, somtimes its almost a stall, other times its just a little blip of a few revs. car idles at 750rpm approx. this problem happens when engine is hot or cold.
thanks for your time
