Recently changed ignition switch and now the security light stays on solid and car will randomly stall while driving.

If the theft light is remaining on solid then the vehicle starting should be disabled. Did the theft light remain on solid previous to this being replaced? If not we need to check the codes. Here is a guide that will help with this:

Also I attached the info below on this system so we need to start with the theft light and then if that does not solve the stalling then we can get a new post started for that because it would not be related and we need to keep each post to one issue. So let's start with the theft and go from there. Thanks
