Hi The car has been stood for a few weeks and now will not start when it does erratic idle no engine power and cuts out. I have tried another battery cleaned maf and throttle body but still the same have these two fault codes is there a procedure to check power to throttle body as there is no movement throttle reset does nothing. Thanks

 

You could pull the plug to the throttle body and check voltage , i don't think you can check voltage to the throttle position sensor without a durametric or factory scan tool , it sounds like the MAF is dead , I'd see if your scan tool can look @ live data and see what the MAF is reading when it's trying to stay running
