Engine Trouble...Misfire/Rough Running

Problems with my engine it seems.



There are two symptoms that I've been able to identify:



1) Sometimes the engine will 'cough' when starting up, almost like it struggles to starts due to lack of fuel. Normally a blip of the accelerator will force it into life. This can happen when hot or cold.



2) Sometimes when running from cold, about 1 minute in, normally during the first 'take off' acceleration from starting, the engine will feel like it starts to run at around 30% power, sometimes it will hickup and start to bounce the car, again a blip of the accelerator will bring it back. If I dont do that the car will stall.



The second problem happens quite often. It will only start to happen once I start driving - leaving the car to idle it sounds perfect, only to start losing power and bouncing when driving.



I've replaced the HT leads, fuel and oil filter - the spark plugs are only a year and a bit old, but have a replacement set to fit next weekend. Apart from this the engine is fine and runs very smoothly, but are there any other things I should look out/try to replace to fix?



Tried to hookup my ODB2 reader but its broken, will grab another next pay check.
