Thanks to all who have vented on this or similar issue. My symptoms are: loss of acceleration after a clunking sound. car engine stays on although sputtering some, of course the engine system light comes on and there was no loss of power steering or brakes. After booting the ignition the engine starts right up like nothing ever happened with the system light staying on. The computer checks showed issues with the Map, Mat, and throttle bearing assembly. After more than a grand these issues remained. I finally replaced the computer for another 1100. and things improved for a while-six weeks or so and when on a 150 mile road trip I had a similar event.
I look fwd to any responses.
