high folks, have this proplem of hunting / decel-accel of its own accord when clutch depressed or in neutral, had this previously with eml on inst panel, fault codes showed O2 sensors which have been changed about two weeks ago, has started to do it again, so far with no warning lights,am thinking throttle body/or maff has gone wrong again none of these showed up on comptuer test , appreciate any thoughts before splashing out a small fortune AGAIN
cheers Ray

SWMBO's 01 1.8 Z18xe engined Zafira did this for yonks until I had the throttle valve body cleaned out, now it only does it now & again. If by some chance yours is the older X18xe1 or whatever engine ( with a throttle cable) then there is an official Dealer modification, which consists of cleaning out the throttle valve body, drilling out one of the holes in it a bit bigger and updating the ECU software.
