Installed Agency Intake on 997.2 Carrera 3.6L.
Car wouldn't idle on start up, would cut out unless revved irrespective of hot or cold. Interestingly would drive fine & idle OK in gear once driven, until engine turned off & re-started. Got the following error codes from Durametric:
1082: Value below lower limit value
1094: Implausable mass air flow ahead of throttle valve. Upper limit value exceeded
1078: Value below lower limit value
1080: Implausible signal
Am running softronic tune. Replaced with standard airbox, all fine.
Seems to me there may be too much air flow through the dual cone air intake that's upsetting things at very low air speeds (i.e. when starting). Wondering how to correct the intake if possible to make it work?
