while the truck is moving, shouldnt the engine shut down? i thought the IP would cut off fuel, but when my shift linkage broke today and i couldn't get it out of gear i turned off the key, thinking this would shut off the engine and would slow me down pretty quick (i was only going about 5 MPH). the engine continued to run until i forced the truck to stall by hitting the brake (i've got the manual tranny). it was wierd. any thoughts?
