Hey guys, just after a bit of advice if I may.

Within the last couple of days my '06 Leggy 2.0R has developed a flatspot in the rev range roughly between 2100 & 3000rpm. I've done a bit of research into it, I bought the car 8 months ago knowing they were prone to them, and so far I've come up with a few things to try myself first like cleaning the MAF sensor, the EGR valves and fuel pump/filter.

The thing that confuses me is that when there's no load on the clutch it will rev freely and smoothly all the way through the range and it idles perfectly at around 8/900rpm. But, when driving the hesitation appears again, surely if it were the EGR valves it would do the same at a standstill or with the clutch disengaged?

Have I missed something or have I misdiagnosed the problem?
