I imagine it was the misfire code. The only time I've read about a flashing CEL it was for misfires. I'm not saying TTR broke my car, in fact I'm actually really happy with the trans mount. It really helped with the shifting. Like tremendously. I remember when I first got the car I sucked at shifting from 1st to 2nd because the car slumped down if I let out the clutch faster than 3 seconds. Now if I just let out it still slumps down but nowhere near as much, it's actually manageable. Those vibrations with the popcorn start and the CEL were scary though and I'll try to see if I can capture it in a log and see what's going on.
Please confirm you don't have a code. Also if you do what code it was.
Are you sure everything is bolted up correctly?
