Galaxy rough running and stalling

Spark plug connections are secure. Misfiring is happening. Could a faulty coil pack cause the check engine light to come on intermittently even if the connections appear solid?

Absolutely. Think of it like a flickering lightbulb. The connection might seem fine, but internally it's shorting out. The ECU detects the misfire and throws up the check engine light. Best bet is to get it properly diagnosed at a workshop to pinpoint the faulty coil.

Thanks. I suspected as much. Took it to the shop. They confirmed it was a defective ignition coil and a faulty connector. Repair cost me 95€. Runs like new now.

Sounds familiar. I had similar symptoms with my old 2008 Opel Vectra. Rough running, stalling, and the dreaded check engine light. Is it misfiring? It felt like driving a tractor sometimes. Check the spark plug connections as well. A loose wire there can cause all kinds of mayhem.
