That makes sense to me, I don’t understand how the code can just not be there. I’ll look at finding a diagnostic specialist if it’s not too expensive but I’m not sure that’s a common thing (in the UK). Thanks

Thank you. I’m not sure if I can afford taking it to a specialist as a student but I could try taking it elsewhere again? I also thought it could be a spark plug issue but both mechanics I’ve taken it to haven’t even mentioned that- I’m not sure how hard it is to just take a look?
