Start drowning.

Dear all, I have a 1997 Opel Corsa with a 1.4 engine. When I start it, it runs rough, the engine runs very unevenly, and after a few seconds, an orange warning light comes on in the dashboard. The only thing I've changed are the spark plugs. I really need your help.

Sincerely,
Rigo Vásquez

Hey friend, check the regulator or change the spark plugs because there's no good combustion

OK, thanks, but as I mentioned before, the only thing I've changed are the spark plugs, but the problem persists.
I need more help...

That's why you should change them and you'll see

It's always best to use a scanner to diagnose the problem causing the warning light to come on, but most likely you have a problem with the ignition coil or a sensor. You should provide more details, such as whether the spark plugs are black, if it's using too much fuel, or if it only misfires at idle or all the time.
