I have a question for anyone who can answer it...I have a 1986 delta 88 with a 3800 engine....I bought the car for little to nothing and am trying to make it run right...when I got there the car had sat for about a year and it fired right up....to good to be true i thought well we checked all the fluids changed the tires and drove it home seem to have a nasty cut out when you first took off....Ok we get it home (about 15 miles from where it was) the exhaust was cherry red right before the convertor...logic answer cat is plugged....we took it off....ran the car for a little while with it off, guess what it still gets really hott leaving the headers....we cleaned the throttle body, mass air sensor, air control motor, changed the fuel filter n plugs and wires....still running rough, and wants to die when you barley touch the gas....exhaust is free and clear and it is still running like it is running out of gas....which it isnt because i had to put gas in it because the gas was old...i also ran injector cleaner threw it still nothing....can someone tell me what the problem with it is?

A year is enough for a car to just sit unless some attention to storing it was taking INDOORS there will be some things to tend to. Bad fuel can easily happen that fast and a host of possible issues but you probably can get thru it if the car is basically sound.
Just fuel cleaner added isn't going to instantly solve a fuel problem AFTER the fact. May require pro injector cleaning and fuel flush - not sure for just a year.
Anything that makes it run rough is going to have a 'chain' reaction down the line causing the hot exhaust on the list and hard on or kill converter.
A maybe is the thing thinks it's always cold via a sensor called CTS (coolant temp sensor) loading it with too much fuel which can choke it, foul up plugs.
Suggest more tests and fixes quickly like fuel pressure, injectors force cleaned and perhaps dump all the fuel, flush and yet another fuel filter. Can also be a bad coil pack jumping spark around.
You can get codes off this thing that may help. Pest but check plugs again too and see if ONE or more is already much different - probably gas fouled or all the same,
