Hi all, got a slight drama with my 07 CRD ute. It feels to me like the engine is "hunting" or getting a lack of fuel/air. But its only apparent between the RPM range of 900 or so to 2000. I try to hold the revs about 1400,etc and the revs jump around plus and minus 100 RPM and keeps doing it. But once the engine reaches over 2000RPM its responsive. This also is when im in neutral at a standstill. When im at speed in any gear it seems to loose power or surge. Doesnt seem to have lost any power. The only mods ive done is a 3" taipan and dawes valve and a dual batt system, however these were fitted months ago with no dramas until now. Im thinking trying to retrieve codes if there are any, and a mate at work has mentioned to clean the MAF sensor. Any ideas/comments will be appreciated. Also if anyone can recommend a shop in Perth who would be able to tackle a problem such as this. Many thanks.
