Toldeo tdi 150 sport idling noisly

[Francy110tdi]

Guys,

My 150 tdi sport toledo, revs erratically when ticking over.

One minute it will be fine, idling at 900rpm then it will rise to 1300rpm for a brief second before coming down to 1100rpm and staying there until it decides to return to 900rpm, which can take up to a minute or so.

Switching the car off and the restarting does not cure the problem unfortantley. plus if you decide to move off with the car at 1100 rpm it will "race on" whilst in first gear if you know what i mean.

Any ideas? maf sensor?

Thanks in Advance

Francy

mine didn't idle like yours, but i did notice the needle move a few cm on idle. at the top of this tdi forum there is a thread re silicone grease, i covered my maf connector and it idles as smooth as a straight 6 engine! (i wish it sounded like one )
