[jamie gsi16v]

mine did this on the way back from pv show, the manifold had broke at the bottom making me loose loadsa power and when it was warm it limited at 4k, ecu fault id say

[Rob-16v]

Thought it mite be something lke that,i hope its not a big prob and it can be reset.

Cheers ROB>

yea stick a code reader on it to read fault and clear it.

Its prob air temp or sometimes a cam sensor- which actually is a phase problem due to the blet being slack
