I have a 2005 5.7 Hemi that stalls when I am slowing down to stop or go around corners. It has been very dangerous a few times. I took it in any the dealer replaced the cam sensor and throttle body. It still stalls. I read that this problem is fixed by replacing the ISC motor. So I took it back in and told them to do that, and they went to start, but the ISC is in the throttle body on the 5.7 hemis,which means it was already replaced. No error codes are showing. Any suggestions.
