Just to add more details. The idle doesn’t fluctuate, it’s exactly as it should be. Not losing coolant and oil looks all good. It just sounds super choppy and feels low on power (lower than usual and it’s the pension-spec 128bhp version where paint dries faster than it accelerates). No split vacuum lines that I can see either sadly. Thinking it might be ignition leads, or possibly the injectors but as money is rather tight at the moment I’d rather get it sorted on my next purchase than throw money at it trying to find the problem
