So after the new throttle body you're still having idle fluctuations? Have you scanned it for codes? Checked and cleaned the idle control valve? Checked for vacuum leaks?

Yes to all no codes no leaks and cleaned everything so lost for reasons
Is it possible it could be a sencor without a code shown for it?

Check compression. Check timing. There could be soft codes that don't cause a CEL to be set.

Still no different tryed all these things just looked at the ECU and its not the one that came with the car what could be wrong with this as the car drives great if I keep it over 2000revs so it must have been put in right or was it?

It could be the wrong computer. It could be bad connections.
