Acceleration Hesitation

[arj256]

I have recently gotten a problem with my car, where when i drive it from start up. It has no power low down in the revs and nearly stalls and then it gets better later on, but now it also has no power higher up in the rev range, and will be really jumpy in the power delivery.
It has only started doing this since its been getting cold.
Im guessing its a dodgy sensor or something?
Anybody know where to look first?

Thanks

lol mines started doing it.. under hard accelerration its like hitting the limiter sometimes..i have to take my foot off the pedal and replace... indicates potentiometer fault for me... or ignition block

coolant temp sensor is a very common fault, id try this first as its very easy to change and fairly cheap
