    Hey guys,

    Thought I'd ask on here before blindly going and prodding at my VR6T. I've got an issue with her whereby once fired up, she will run fine, but then the revs will rise a bit and she dies, and upon restarting she is a pig to restart - popping and banging until eventually she goes. Once running, she's flat as a fart when sticking the throttle on, really lumpy and pops and bangs some more. It's an OBD2 ECU running United Motorsport software and I've tried isolating the MAF with no success. She had a bit of an episode a while ago where there was an airlock near the coolant temp sensor, so ran incredibly rich, sooting everything up... so wondering if this could be Lambda related? Thoughts?
