RPM drops while driving

zacki

Respected
1. Start the car
2. RPM goes up and drops to 1000 rpm
3. Suddenly, it will goes up again to 1500 rpm and stays there and the engine lights lit up
4. Try to drive it and the RPM drops until the engine will turn off.

What could be the cause? Hope you can help me on this one, thanks!

Is the engine cold when it does this or hot?

The CEL is your friend, pull the code and that should surely identify your issue.

How does the car run when it's at normal operating temp?

You replaced it and the same code came back? What was the code?

I agree with above too, try cleaning your IACV.
