Since I've had my 92' SC300 it runs very well, never an issue while it's running, but if I've been driving a while then shut it off to run into a store, for example, when I try to start it again it will turn over and start, but within a few seconds will bog down and die. It takes anywhere from 5-25 tries to get it to stay running again, and there is no check engine light on. I've read a lot of posts and came to the conclusion that it is possibly the ECU/ECM, IAC, or Idle Speed Control sensor/module, but I'm still not sure exactly. I've just replaced the fuel filter with no change.
A diagnosis of this issue and the possible fixes would be much appreciated. Thanks in advance for your input and assistance.
