Thank you so much for your understanding and thoughtful advice! I really appreciate your suggestion to use carcheck123. Checking the MOT history of my Nissan Terrano sounds like a great idea to gather more information and potentially uncover any relevant past issues. I will definitely give it a try and see if it helps shed some light on the strange starting problem. Your kind words and well wishes mean a lot to me. Thanks again for your support, and I'm hopeful that I'll be able to resolve the issue soon.
