Thanks for the reply. Can you share more about the symptoms you saw with your Astra? Did diagnostic codes point right to the crankshaft sensor, or was it a guess based on how it ran?

Yeah, the diagnostic codes were all over the place, timing issues and whatnot. Eventually, the mechanic suspected the crankshaft sensor. I would say it's best to get it checked in a workshop to be sure

Thanks for sharing your experience. It helped confirm what I thought. It was a bad camshaft sensor connection, like I first thought. I fixed the connection and cleared the error. The car runs fine now. Thanks again.

Whoa, sounds familiar! I had similar rough idling and engine misfire drama with my old Vauxhall Astra. Turned out to be a dodgy crankshaft sensor. Made the car run like a bag of nails!
