booloveblankie 11 Report post Posted October 1, 2016 Hi guys, My E30 is having issues... Again. Under specific loading conditions, there's a notable loss of power and an audible sound between 3000-4000rpm. I've tried to capture it in the video but didn't do too well. That and my "camera mount" kept talking. Typically part throttle under acceleration on the flat, or anything from half to full throttle up hill. Sounds like launch control is engaged (IE unburned fuel igniting in the exhaust). It doesn't seem to occur when the engine is cold. Apologies for the video... Couldn't find the right mount to get good footage of the tach so I had to make do with a friend's arm. Any help is appreciated! Quote Share this post Link to post Share on other sites
