Hello, I drive a Hyundai Santa Fe and have a strange problem. Just wanted to start on vacation, then at the traffic light the engine shuts down. It jerked short and then there was nothing more. Panning service arrived about half an hour later and curious way the car jumped again. He stank improbably and squirted powerfully out of the exhaust. continued my trip and after 250km the CHECK ENGINE light went on. Drive next day into the Hyundai contract workshop, which read the error from mixture to Magnificent. Recommended me to refuel the “good” fuel. Well, I refueled super and drove almost two tank fillings empty and the error was still there. Drive on to my workshop and they started to check: spark plugs ok. Lamdasonde ok. ignition coil ok. all hoses or vacuum cable ok. You suspect an electrical error (control unit) Please urgently for help, who has a similar or even same problem and hasts got fixed. Thanks in advance.
