Argh, my Pirelli developed a misfire. Literally the same day, or maybe it started the day before, having my Scorpion exhaust fitted.
Rough at idle on start up, smooths once it's warmed up a bit but got a flashing EML when idling warm or not, and a constant EML the rest of the time.
135,000 miles it's probably an injector isn't it. Plugs done in the last service last year. I had one injector done about 2.5/3 years ago. Would you just change the other three this time? The car is a keeper, want to take it over a quarter of a million miles for sure (bought at 50k)
