Hi All, 2004 disco auto has started hunting around 2500rpm. Done all the usual checks. Injector loom cleaned MAP sensor, Turbo waste gate free hoses all good . No faults logged . I am running out of ideas. Can anyone help please

Well After No Help! I changed the air flow metre for a cheep ebay special and off she go,s again. The figures from the old maf unit where ok when stationary but was failing under load.
