Title: 2.2 erratic idling
Post by: Shaman61 on 06 November 2009, 14:55:08: Hi,
my 2.2 has just started erratic idling/stalling whilst driving. Disconnected the MAF and all is fine. No eng mgt light when connected. Maybe a daft question but is this MAF definitely knackered? Are there any serious consequences of driving whilst disconnected until I can get a new one? Thanks in advance for any help.

I wouldn't spend any money on replacing bits unless the answer to this is "within the last year, following Grumpy's guide to the letter".
I imagine that the map invoked when you disconnect the MAF could well mask the symptoms caused by breather/IACV* problems.

*Edit, might not be such a thing on the 2.2...?

Correct, no ICV on 2.2/2.6/3.2
