81 question/problem
ive got an 81 all stock rebuilt tranny well i went to new mexico and left the car here in texas i hop in it to goto work took 6-7 tries for it to fire up ran for maybe thirty seconds died again after about 15 minutes of dying and restarting it finally caught idle at 500 rpms before it idle'd around 800-1000 anyways i back the car out of the driveway give it gas and it dies anything over 1500 rpm it falls on its face huge drop it power and barely running so my question is this just a clogged catalytic converter or something else?

How long has that gas been in there? Goes bad in just a few months. Also the fuel filter is on the front of the carb at the end of the fuel line. It just unscrews, pull it out and clean it with carb cleaner or replace it don't forget to put the spring back in and if it is a one direction filter take care to put it in right.

alright so i pulled my fuel filter off today held on by two clamps its a one way blasted it with carb cleaner seemed pretty clean clamped it back on it ran better but still a little sluggish and i somehow burnt a half tank of gas in a couple hours so im wondering if it could be misfiring i checked that also all my plug wire were fine no tears burns ect.. going to pull the plugs tommorow to see if any are fouled any other suggestions???

How does the car run when its in Park or Neutral? Can you get it to rev past 1500 rpm then? I agree with the other posters that it may be sometype of fuel delivery problem. Maybe the last time you filled the tank you got some bad gas...

Did you have some "friends" put something into your fuel tank?
Remove the O2 sensor and see if it runs better. If so, then cat is probably plugged. This will set an error and engine will run in open loop when you try this.
