"your carburator has been tinkered with"

Alas, when it failed the emissions test several years ago, it was worked on and after that I remember it not running good anymore, except for good idling when the engine is warm. I'm indecisive because the car could maybe best be categorized as beyond econonical repair.

I heard that it has a computer and you have confirmed that.

"properly working carb on your vehicle which is in a good state of tune you would have a hard time improving on factory settings"

I agree with that, and I have considered replacing or rebuilding the carb.
