afew problems , any idea's

in the mornings my car idies funny , it starts at 1200rpm which is normal the goes up to 1400rpm is this normal ?

also it doesnt want to pull in the mornings either , ive had the window down and sounds like the turbo isnt spinning up as it should do .

i stopped at the shop in the morning to get a paper and started her back up and was driving fine . pulling and the turbo is spinning up .

i was think that its gone in to limp mode and when i turned it off and back on again it re-set itself and was like **** of a shovel !

theres a knocking noise when i go round a corner over a bump and when i put my foot down going round a corner too . i was think its the drvie shaft but it sounds like its going down the centre of the car , which is making me think its not the drive shaft .

it doesnt knock when its n full lock going slow tho

any ideas ?
