Technical Throttle body

[Planeboy]

Rallycinq plz advice me on my new problem with misfire at low revs.

Is the throttle body removed by the 3 spline screws and then I can get to throttle control valve or is there another way?

I dnt think its my timing belt as is been fine for 6 months.

Only recently it started dropping ideling to the point now where is activating low pressure on really hot days

The fact that I covered where air goes in to the idle valve and it started missing after that leads me to idle valve stuck or not working right. Engine managment light is off.

Ideling goes up and down a bit but when i press petrol car vibrates but after 2000rpm it goes away

Any one who can diagnose what sensor it is, is welcome to help. I think its a dirty sensor as timing belt is new and was done right

I'd still check the timing, its only half an hour out of your life.

I am not as familiar with the MPi body as i am with the SPi one, so I'll need to bow out at this point.

Cheers
