Power Amplifier Question

I'm working now to simulate and implement power amplifier , Which is intended to be tuned to 85 meg , but the problem in orcad capture that when i cahnge the value of coil to fine adjust the req. freq. , i found that the freq. doesn't change ( it become fixed at 83MHZ ) plus the o/p wave form is decreasing and waveform distorted.

I want to know what is my problem , Can anyone help me ?

I know this is weired, but the green circle across the emitter means its disconnected :)
