Can anyone identify this part please.
vRSAlex:
Is the car mapped?
There were/are issues with valve float at high rpm that can cause missfires.
I guess you had the coilpacks replaced to try and solve this missfire issue? Did the plugs get changed too?

I've just changed 4 weeks old spark plugs due to misfires :fighting:

I changed the plugs about 2000 miles ago.
Im thinking its not exactly a missfire now, as i said in my other thread, the car seems to 'hold back' sort of when i drive it from cold. When i start the car from cold ive checked and the tumble flap motor opens or closes(not sure which way round it works) as it should and the car goes into the 'cold the start sequence' (revs go up slightly to warm the engine), then after a few seconds or maybe a minute the revs drop down to normal again which is fine and normal(the tumble flap motor opens or closes again).
My problem is the car wont drive properly during this 'sequence'. It seems to 'hold back' until the tumble flap motor finishes its 'sequence'.
Now this is nearly the exact feeling i get when driving in the high rev range.
Ive heard the 'tumble flap' sequence works at low and high revs but just cant get my head round what could be the problem with it???? :confused:

Also, ive just remembered i had a fault code come up a while back.
Does anyone know this code 01809 actuator motor temp flap? Would this be a connected issue?
