Hey peeps can someone please help
R33 series 2 manual turbo
Catback exhaust
Spitfire coilpacks
Bigger intercooler
Mushroom pod filter
Hks bov
I have recently serviced my car changed spark plugs at an 0.8 gap changed oil filter etc.
When changing the plugs the whole valley was flooded with old oil cleaned it out of valley. Cleaned coilpacks with wd40.
Went to start and wouldn't kick. Ran diagnostic test and was getting error 12 Afm. Went and changed the afm with a spare I had car started straight away. Went for a drive and noticed was running rough then at 4500rpm once the turbo boosted the engine light would flicker on and off and car stalled.
Got home and decided to change manual boost controller to a Gfb atomic. Once changed still had the issue. Ran error codes and came back as codes 11 and 12. Check hoses for leak and reconnected boost controller and ran diagnostic and read 55.
Took for another drive today thinking it would be alright now it will boost to 4500rpm again same problem the engine light comes on stalls after letting off accelerator.
Please help im stumped any ideas
