the ecu? The harness was replaced when the TT swap was done ~10 years ago so all I did was change a few broken connectors. The stalling really is the oddest thing. It acts exactly like my Z did with bov's which makes me think there is a vac/boost leak but I've boost tested this car 100 times in the past few days and it's tight as a drum with the exception of the egr area. but it's not a major leak at all and I'm surprised the symptoms are so severe. Maybe it's because when I let off the gas and the EGR opens the engine can't compensate for the vac leak and incoming exhaust gas. It very rarely dies but it will drop to ~500rpms or just below and make the dash lights come on before it springs back to life. Thought it has died on many occasions doing this exact thing.
