1988 Corsica wont run when hot

[david1295]

My 1988 Corsica 2.8, Automatic, not updated to speed density, will not run properly when hot. It's fine when cold, but once it gets hot, turned off, and then restarted, it runs slowly and very rough, and will die completely if you push the accelerator. It did this when I got it 2 years ago, and finally it turned out tio be the fuel pressure regulator. I just yesterday replaced the FPR again, but today it tried to do the same thing. Not as bad or as long, but enough to make me wonder if it's something else. Any ideas would be appreciated.

pretty common thing is ignition module, which will do this and eventually will fail for good...and also crank sensor.
