high speed - very minor misfire!

can all you experts on here help this newbie with an annoying slight misfire?
My 2005 TDV6 (105k miles) has a very slight high speed misfire which only appears after the engine has been running for say half an hour or so. Fuel filter is new, I am using an additive in the fuel to keep the injectors clean and no lights are appearing on the dash and no fault codes logged.

I suspect that as the heat under the bonnet rises - something in the engine wiring loom is breaking down and causing this slight misfire - is this a known issue?? or am I way off track??

The misfire is very slight and quite intermittent.

Any help or advice greatfully appreciated. Smile

just thought I would write an update to this thread.

The problem was caused by a TINY hole in one of the injector pipes ( had been rubbing)

New pipe solved the problem
