Got rough running and sqeaks when starting from cold :-?seems to ease off/return to normal as car gets up to temp,and is then fine. car goes like slippery snot in fact (except last night on way home it seemed to cut out or stutter as i hit a bump on motorway s road just for a milly second)
rough running;always starts but recently it seems to spin more freely just before cathing/firing up. then revs rise higher and hang longer than normal before settling on about 1000rpm as normal(?)when cold,this is accompanied by a fut fut fut as if a problem on one cylinder and excessive vibration as if miss firing.
squeak;sounds like a screeching fan belt but intermitant more metalic and quieter, mostly in cold weather, sometimes not at all in warm weather but always squeaks when in reverse anything up to 2 mins after starting.Squeek appeared just after new alternator i think.
allow car to warm in neutral for 2 -3 mins before reversing out of drive and no squeek unless its really cold/frosty, rough running goes gradually in same time period but fut fut will take about 5 mins to stop.
then car is smooth quiet and drives well.
recent history;cam belt in feb and tensioner.think i should have done water pump as well :-/,aux belt and tensioner, followed by oil cooler cover(leak)

, breathers,new cam covers,s plug leads and plugs.(oil in plug holes)
suspect;dis pack?water leak and oil leak affected it? plug leads damaged due to oil then straining dis/water on dis pack? how to test?
LOose manifold or broken studs(as seen on here,why they break)?
had car on ramp no blowing but car was well warm. did paper clip test couple of weeks ago when all this started no codes,
any help much appreciated, Chris.
