Hi Sorry i forgot to add that i have removed the AFM and am running with the MAP sensor and IAT sensor. Thanks

Hi I have a 97 WRX fitted with VF34, front mount, pod filter and G4 plug in ecu, i've used the auto tune to start tuning the ecu, my problem is when neutral if i hold the engine rev's at about 1500 the engine starts hunting around up and down and the afr go's lean then normal then lean etc. Any help? Thanks
