Default Engine stalled

2001 XKR was running fine, then stalled when waiting for a traffic light after crusing at 70 MPH. Restart and stalled several times. Engine runs rough at low rpm but sounds OK at higher rpms. Almost sounds like fouled plugs or maybe bad coils, I've replaced several coils in the past after reading the codes that log cylinder misfires. I managed to get her home, but no engine codes found. Will investigate this weekend, any ideas??

114,000 miles, rebuilt the supercharger many miles ago due to cracked internal coupler (who thought of that spring loaded POS?)

Could be a throttle body problem. Try doing a hard reset first. Also very possible that one of the fuel pumps failed.

Could be an air leak. Stops it maintaining idle / makes starting tough.

Found one supercharger inlet duct partially sucked in, allowing air to leak. There is a technical bulletin addressing this problem, 303-57. Quick fix was to reassemble using permatex gasket sealer on the rubber flange to increase adhesion to the clamp plates.

Thanks for all responses!
