The carb. your running im sorry to say is junk. The only way i ever fixed that problem was to buy a new one or send it out for a complete rebuild. The elec. run your fuel curve and th esoleniod on those carbs always go out, then the car runs like junk and smokes. My advise is to go buy a new one, call the carb shop and see what they can do for you.

Sounds like your computer is not going into the closed loop mode as needed. You're running in the "limp home" mode which is pretty sloppy. Need to find out why the computer is not working right. Find a friend or a mechanic with a scanner and chech out the system. These cars run pretty good when right and get 22 - 24 mpg easy. Worth spending a few bucks on to get it right. tom
