Had 2 or 3 occurances of a slightly hunting idle on my MY00 today, along with a couple of cases of missing/lack of power when crawling along in traffic.

As it's an MY00 I suspect it's the MAF but I thought I would have a look at the majority of sensors tonight and give them all clean.

ICV (Idle speed control valve) was a bit gunky and very sticky in movement. However, whilst cleaning, pulling and pushing the plunger it fell into several bits (Plonker).

Hopefully my local dealer will be open tommorrow so I can get a new one, if it's cheap enough. If not I shall just get a MAF from the dealer and get the ICV from a breakers.

why do these things always happen at Christmas.....when money is short and everywhere is shut

 

Cos that when you're not at work, and you've got time to fiddle!!

 

Have you tried Grade A Subaru Scott?

 

found the price of an ICV elsewhere using the search....OUCH !!!! yet another un-justfied price...so huge I ain't gonna post it here.

Will be ringing Grade A and others in the morning.....
