Opel Adam no longer starts since the spark plugs and ignition coils have been replaced

Hello everyone, I have a problem with my Opel Adam (built in 2012, gasoline engine). Symptoms: black smoke from the exhaust when accelerating, check engine light on, loss of power, engine runs rough, jerks when accelerating, won't start, poor fuel consumption, engine stalls at idle and shakes. I suspect that the ignition coil is defective or that there are misfires. Has anyone ever had similar problems? What has helped you? How did the repair go at the workshop? Thanks for your help!

Summary of the thread

The Opel Adam is experiencing issues such as black smoke, check engine light, loss of power, rough running, and failure to start after replacing spark plugs and ignition coils. The initial suspicion is a defective ignition coil or misfires. A similar case with an Opel Corsa suggested that a faulty engine control unit could also cause these symptoms. It is recommended to have the engine control unit checked in a workshop, alongside verifying the ignition system's condition, to resolve the problem.

Hello, I had a similar problem with my Opel Corsa (built in 2014, also petrol). I have a bit of experience with cars and prefer to go to the garage when I have major problems. In my case, the symptoms were almost identical: black smoke, check engine light, loss of power and rough engine running. After the diagnosis in the workshop, it turned out that the engine control unit was defective. The repair cost me around 1000 euros, but after that my Corsa ran perfectly again. Your assumption about the ignition coil may of course also be correct, but if you have similar symptoms to mine, it could also be the control unit. I would recommend that you have this checked in a workshop. What exact engine version does your Adam have? With a few more details, I may be able to help even better. Good luck with the repair!

Hey, thanks for your experience! My Adam has the 1.4 liter engine (Z14XEL). By the way, I'm at 103456 km and did the last service about 6 months ago. I'll definitely bring up your tip about the engine control unit when I go to the garage. Hopefully it's nothing too expensive. Thanks again and best regards!

Hey, cool to hear from you again and thanks for the info. Well, with my Corsa it was a similar mileage (approx. 105000 km) when the problems occurred. The 1.4 liter engine in the Adam is prone to such symptoms, especially if the ignition system is not in top condition. Another tip: After replacing my engine control unit, I also had all the spark plugs and the ignition coil checked and replaced if necessary. This significantly improved the overall engine performance and I haven't had any more problems since. Don't get too stressed about the cost, but be prepared for a thorough check. Explain your symptoms and your suspicions about the ignition coil and the engine control unit to the workshop so that they can carry out a specific check. I hope this helps you and that your Adam will soon be running like new again! Best wishes and good luck at the workshop!

Thanks for the tip, I will do that. I also hope that my Adam will soon be running smoothly again. I'll definitely talk to the garage about it and see what their diagnosis is. Keep your fingers crossed for me! Best regards and thanks again for your support!
