Engine Performance problem
1989 Chevy Corsica 6 cyl Front Wheel Drive Automatic 122000 miles

Our corsica's engies is dieing just off idle it starts just fine and idles good, if transmission is put into gear it's ok but as soon as gas peddal is depressed it dies, does the same thing in netural, it quit doing it for 1 day and has since again started it. You can pump the gas peddal and get it to rev up but it still acts like it wants to quit running. We put a new crank sensor in it a year ago when we were having trouble with it along with a spark module, coils wires etc just to find out it was an injector. If this wasn't a hatch back corsica which there isn't a lot of them around I'd run it into a wall " if it would run long enough" So far while we driving it, it hasn't really given us any trouble, What the hell is with this thing?

Are there any applicable mil codes? You should be able to check mil codes, yourself. Use a gage and check fuel pressure, some of the national brand auto stores used to loan out a fuel pressure gage, if you don't have one. To start, I'd want to know if the system is running rich or lean?

It doesn't show any codes other then 12 this morning it was acting up I tried it about 3 times, went back and tried it again a few minutes later and it was fine, drove it around the block and ran great, im sure it will act up again, always does. Last time we checked the fuel pressure it had good fuel pressure and good volume. This dam car has also been known for fuel injector trouble. I do know with this system if one injector goes bad they all quit. I'd understand if this car had 200,000 miles on it but it's just turned over 100, 00 and we usually only put 5000 a year on it, and it was really owned by an old lady till we bought it with 85,000

Intermittent issues can be hard to track. You have to test when the problem is ongoing. In those years, they had a lot of trouble with maf sensors, so they changed the system to a speed density system, uses the map sensor input. They changed the memcal in the computer. I don't know if that conversion was done on your vehicle? I'd remove the throttle-body and clean it, all passages, check the iac and tps.
