Since then the car seems to stutter slightley when im driving through town in 2nd gear. Does cleaning the throttle body have an effect on how much much power i have to keep on in low gears?
Sorry if this is a stupid question im not exactly mechanically minded.

Im not familiar with Corsas, but this stuttering may exist due to a leak on the throttle body joins on the engine side of the air flow meter. Check for any rubber hosing that has split or parts not tightened in correctly and that orings are present if there are any needed. Having said that, in my experience with this problem, the stuttering is more noticeable with faster acceleration, i,e its most noticeable in 1st gear, less so in 2nd gear and so on.
