So far, on my 96 Cobra, I've stalled out twice at about 30mph, after downshifting to third gear. I'm not hitting the ignition switch accidentially, and I'm not stalling it b/c I don't know how to drive a manual. I'm on the brakes just a little bit, and the car just dies and rolls to a stop. It is really annoying and dangerous. The only mods are a K&N filter, Borla, Bassani, and some others.
