    Car has throttle body injection. I did take the top and injectors apart. All looked very clean but still ran the same. If i pump the throttle it will stay running.

    Car has the throttle body injection and it is a 4.1 engine. I did add 4 gal of fresh fuel but did not drain old fuel. Less than 1/4 tank.

    fuel turns to varnish under pressure, so in the tank you will be OK with such a small amount of fuel in the tank. In the throttle body varnish will have formed inside the injectors. It is nearly impossible to get it out of the injectors. You could try running it for a while with some injector cleaner in the tank, I doubt the problem will go away with out replacing injectors.

check for plugged exhaust system, dirty air filter, vacuum leaks, those have a mile of vacuum hoses. Also, check for bad fuel pump.

Need to replace a fuel filter on a 1983 caddilac seville

Because of the age of the car, I'm not exactly sure where the filter is - for most Cadillacs it is on the fuel line under the car near the front on the inside side of the frame. However, that usually won't cause your problem - the fuel pump is probably ceased.

My 1983 cadillac seville will not stay idle unless pumping the gas It will shut off otherwise. changed fuel filter and fuel injectors but still shutting off and popping sound.

this could be a fuel pressure problem or volume problem.if its to low and you push on the gas pedal you are opening the injectors longer to allow more gas to could also be a stuck open egr valve causing a vacuum leak stalling the car at idle.the popping sound you hear sounds like either one of these,lean running condition.

1995 Cadillac Seville SLS stalls out

It sounds like it may be time for a new fuel filter, try replacing the fuel filter first. The filter has a life of 30,000 miles or one year, if it has not been changed, good chance that it's the fuel filter. Take not that a dirty fuel filter will make your fuel pump run hotter and will shorten the life of the fuel pump which is the more costly repair of the two. Good luck and keep me posted, Be glad to help you get your car running 100% again.
