Flat Spotting at around 100mph.

[gad]

Has anyone experienced any problems with the V8S pre cat flat spotting at 100mph or so in fourth or fifth gear??? If so can it be sorted and where??

Cheers GAD.

I assume it is the speed and not the rpm that is the same, which is unusual!
I would guess it is fuel or spark starvation, or maybe a badly choked air filter restricting air flow.
Not sure if there is a road speed input to the ECU, if there is maybe there is a problem with that or the sensor??
Someone with a V8S would know more than I do!
