I don't know what other problems you have read, so could you describe what's going on?

And if you have tried to do any testing?

I am not going to read about the problems for some other car. I would have no way of knowing if each and every symptom was the same as yours. Or if you have symptoms that they did not.

So after the engine is at normal operation temperature, you can not get it to run above idle?

Do a test to see if it's because it's starving for fuel.

While working the throttle, spray starting fluid in it in an attempt to get the RPM up.
