XT25 will only idle after removing loader

[NT304]

I have a 3 year old Nortrac XT25 (Foton) with a Koyker 140 loader. I removed the loader for the first time and now tractor engine will only idle. Did not disrupt any either cable and even when you manually move throttle control at pump it won't rev. Am I missing something here? Any suggestions greatly appreciated.
