Hi everyone, finally put my big girl pants on and bought my first MG (ZT+ CDTi pre-facelift) and, like any 15 year old car, there are a couple issues. The first is a horrific juddering when the car reaches 3000rpm in any gear. The car is quiet on start up and runs beautifully below 3000rpm but judders violently when it gets there, it doesn’t smoke or any other nastiness. I’d like to hope it’s just time for a new MAF sensor, but if anyone could shed some light on other likely problems, I’d be forever grateful!

Another (very minor) issue is that the clutch seems overly stiff, but the bite point is low, doesn’t slip, gears change smoothly etc etc. Is there anything anyone could recommend I do that might lighten up the clutch a little?

Here’s a picture of her, because I already like showing her off!
