MG ZR ZS ZT Technical - Engine missing 3500 rpm full throttle

fuel pump a Jan 2005 registered MG ZT 1.8 turbo. It has done 67000 miles and I bought it in May 2006 with 1634 miles on it.

In normal road use I don't use the full bore acceleration power of my car very often so I don

To paraphrase the Quantas fault report of many years ago
(http://www.austech.info/general-chat/49556-qantas-fault-reports-lol.html)

"Engine found after short search under bonnet ..."

Sorry. It could probably be absolutely anything, especially if it's irregular and/or intermittent. If fuel starvation i.e. pump problems I'd have expected the problem to continue while at full throttle. If it always happens the same way at the same point in the acceleration cycle then it seems more likely something to do with one or more of the sensors for the engine management. Any fault codes? Plug condition?

David,
A bad Spark Plug will act lie this.
Easy enough to change.
