Need help in MI
 

I have a very troubled 83 rx7, i need someone to help me get it running right. Ill pay for help, i just need it going and cant find anyone to work on it. message me for details. Im in southern MI near jackson.

whats the issue i have an 83

Idling at 2k rpm, when in neutral it revs fine but in gear it won't make power, it barely goes and chugs a lot, someone said it could be my timing, carb, or my cat could be plugged. I'm taking it in for a diagnostic tomorrow. Oh and in 4th gear at 4500 rpm it will only go about 50mph.
