Just an update, replaced hoses for the map sensor, pulled off the afm and gave it a thourough clean out, undid the 4 screws where the plug goes into, pulled it out n noticed a fair bit of gunk on the 4 contact pins..
Well after a clean out, I'm happy to say it's been 4 days now and the car is running sweet, the rev cut out/stutter has disappeared. Added a pod conversion aswell n the car I running smooth as silk. Thank god for ecutalk n my consult cable!
Ty for the input n helpful advice guys.
