Hello all:
I'm in my second season of ownership of a 2006 Brammo Atom 2 with about 14k miles. GM Ecotec supercharged. I have chassis #50, which I believe was among the handful of cars that TMI acquired from Brammo and used for the Atom Experience until about 2008. On July 4, I decided to take the Atom to a Cars and Coffee that I like in PA on the first and third Saturdays of every month. It's about 30 back country miles from my house, no better way to spend a Saturday morning. I got there without any problem. Chatted with the boys for about an hour then jumped in to head home. I got about two miles in, just after to merging onto a 55 mph stretch of road, when I lost all power. The engine was still running, but only at idle RPM and it sounded very rough, there was an unusually loud rap-rap-rap-rap-rap like I had a cylinder missing or something. I coasted to the side of road and noticed that no matter how far I depressed the throttle, it had absolutely no effect on what the engine was doing. The engine just putted away. I shut the car off, trying to figure out how I was going to get home. After about 5 minutes, I decided to try starting it again, and behold, it was like nothing ever happened. I drove it home without any further problems, and I chalk it up to a one time glitch.
Fast forward to today. I haven't used the car since the 4th, but since its another C&C day this morning I decided to take it again. Get there no problem, hang out for about 1/2 hour and then get in to head home. IN THE EXACT SAME SPOT, ON THE EXACT SAME STRETCH OF ROAD, THE SAME THING HAPPENED. I pull over and figure that I know what to do, just turn off and turn on again. I try it, and it starts, but I'm getting the same rough idle and no throttle response. I turn off again, wait about three minutes this time, and try starting again. This time it's all back to normal, and I make it home without any more problems, exactly like two weeks ago.
The tank was about 3/4 full the first time and a little less than half today. Has anyone ever experienced or heard of anything like it?? I want to point my mechanic in the right direction (he told me he often uses this forum for info when he works on my car). I appreciate any advice someone may have. Thanks, Jim
