Hi guys!
At my wits end with my 1.2 69bhp 63 plate 500S. I'll try to make a long story short.. it has an intermittent misfire. Also, when driving it at high speeds (70mph+), sometimes the engine management light will come on and the car starts chugging as if I'm running out of petrol. When the engine is switched off and back on, the EM light goes off and car runs as normal once again (still with the intermittent misfire but minus the chugging). When plugged into the diagnostic, the fault code reads as misfire cylinder 3 along with a few others. However, everything that the codes refer to I've had replaced. Replaced coil, spark plugs, lambada sensor etc etc with genuine parts.. it's also recently had a software re-flash for a problem with it being underpowered.
Does anyone have any experience of this? Helpppp!
