It must have run like a bag of hammers so clearly the garage sorted the belt and got it right. Following this my revs would go higher than 3000 but only to about 3500 for an extended period. So something might have got bent or an exhaust valve spring might have gone soft. Nothing to see on the plug in computer until going over the 3500 ish. The exhaust gas was directed into the inlet manifold, limp mode and the rest was history. Assuming you hadn't burnt the manifold sensor the car would restart and run as good as gold. I had the car for 5 years in this state and just never ran it above 3500.

Thanks for that but traced it down to a safety feature that prevents over raving when stationary (there a more comprehensive response in one of my previous posts .
