Hi guys I'm new here been following but nvr posted I need some help I bought a 1995 z28 a few days ago it ran very well even drove it 3 hours back home well I shut it off once I made it home went out later to crank and she was bogged and puttering when I went to drive even popen from the exhaust like it was over loading on fuel so I left her alone went out a few hours later and dine again't but she has done it twice so far any idea

 

Not clear what happened after you "left her alone went out a few hours later and dine again't but she has done it twice so far....." Are you saying it did or did not start after letting it sit? If it started, did it continue to bog and putter, or did it run OK?

 

It continued and I would have to cut off and let set for a hour and she cranks rite up fine again

 

Sounds like a heat soak problem. Several possibilities:

-Ignition Control Module (ICM) - you can take this to an auto parts store and have them test it. Make sure they test it several times to make sure it gets good and hot. In any case, consider spacing the ICM off the head a bit to allow for more heat transfer:

You need an OBD-I scanner (with a 16-pin adapter for your 95's oddball ALDL connector), or software like Scan9495:
