Engine cut-off problem in a Nissan Note Diesel

Good evening to the community. I have a 2016 Nissan Note with a diesel engine and 163,000 kilometers. I am facing the following problem: When driving with light throttle, the engine starts to misfire. As soon as I press the gas pedal, the problem is resolved, but when I release it, the misfiring returns. No fault is shown on the car's computer. I have changed all the sensors and checked the fuel pump and injectors. What could be causing this problem?

Start by checking the condition of the EGR valve, as it might be clogged or malfunctioning, causing misfires at low throttle. A thorough cleaning or replacement might be necessary. Let me know how it goes or if you have any further questions.

Cleaning the EGR and MAF and it continues. Should I check something electrical?

Yes, check the ignition system, particularly the spark plugs and ignition coils. Worn or faulty spark plugs can cause misfires, especially at low throttle. Inspect them for wear or damage and replace if necessary. Let me know if this resolves the issue or if you need further assistance.
