This just happened to me. Unfortunate I was at a left turn intersection in the middle of the Highway too . The car will not run.

It dies a few seconds after cranking and will not respond to the gas pedal at all. I checked the codes and a DSW B2366 came up. Anyone have any idea what is going on here?

The car is tuned speed density and has a ls2 throttle body. Any input is greatly appreciated.

 

AIRC, The TPS in the throttle body took a dump. Will lock out throttle activity.
Prevents engine run away.

 

I thought this might be the case. I hope all i have to do is replace the throttle body or the best case would be just the tps if possible. I did get a code a few months bach that was throttle body related. When i would coast in gear downhill for a long time it would throw a check engine light and go into reduced power mode. I logged the code and my tuner said it was a tps issue. I guess it just finally let go?
