My Saxo has started getting a little bit kangerooey recently and when driving it sometimes feel like the car is being held back. Couple to this have been getting shocked at how often having to go to petrol station, even when doing more economical motorway driving at 65ish.
Has anyone any ideas? I only had it serviced 7 weeks ago ...
Kangeroo & low mpg recently

Rough running coupled with high fuel consumption is usually a sign that the coolant temperature sensor is kaput, and the ECU thinks the engine is cold all the time and is effectively running with the choke out. There might be 2 sensors on the head / stat housing, one feeding the ECU the other the temp gauge (if fitted). For some reason I think the ECU sensor is blue. Find it and measure its resistance engine hot and cold. If the two figures are not markedly different (or it reads 0 or infinity ohms cold) then change it.
Unlikely - if the thing is supplying a rich mixture as for a cold start it will tend to cool the combustion. (In my youth valves would burn out if an engine ran lean!)
Perhaps the temperature gauge is doing its job - feel the radiator and see if its cold in parts when the engine is hot - especially at the bottom. In any case a flush won't hurt and may clear blocked bottom tubes.
