Have only noticed this recently when manouvering at low speed e.g in to a parking space. When coming off throttle the revs are dipping below 1000rpm causing a slight judder, it recovers than idles around 1100rpm is this too low?

Would I be right thinking either the MAP or ICV might be the problem?

 

Mine sometimes does this as well, when coming off the clutch it dips below 1k and judders a tiny bit sometimes when manouvering to park.

 

Nope its perfectly normal. If you do an ECU reset and then the idle learn process(see FAQ) it does make things better for a while until there is a substantial change in ambient temperature.

 

great one , i was going to search on the same thing this eveing as mine has started doing the same.

 

Hehe must be temperature related then!

 

Normal, especially when cold. After a ECU rset it will be worse until it learns.

 

ECU learning takes 10 mins.

ECU reset can just mask the problem for a very short time, not usually solving the problem.

 

MB's Idle Thread now in my sig...I've been recommending it alot recently and may prove worthwhile to the OP in the long run.
