Hello just looking for some help/advice.
the car is a 92 soarer with 1jz.

My issue is the 1jz will idle for a second or two then die when the car is warm. As the rpm is dropping you cannot rev it to stay started.

If you startup and rev rate away to 3000-3500rpm for 30 seconds and let off, it stays running. On cold start it starts no problem and stays running thanks to the fast idle.

Here is a video i made

Today i cleaned the iacv and didnt do anything.

Has anyone ever had this issue before?
maybe the ecu?

It's gotta do with the iscv or the tps. I don't know which one for sure because I had the same issue, but it wouldn't happen all the time. I replaced both and the problem went away.
