Have you changed the lambert sensor in the exhaust if its v8 then you will have 2.this controls emissions fueling etc. id say 80% its the problem or the cat itself is blocked

Sounds to me like it is misfiring badly or is overfueling.im assuming this is a petrol engine.if its misfiring it is not burning the fuel properly thus causing the catlytic convertor to heat up excessively and destroying it.u need to check high tension leads .spark plugs should be correct type ,and coils. replace convertor afterwards as old one would be destroyed with that heat

    check fuel pressure regulator also.high fuel pressure may do this.

Won't start at times


Cat. converter in your exhaust may be clogged, building up backpressure as the engine runs. Pressure slowly releases over time, allowing your engine to start after sitting. A clogged catalytic converter has been known to get so hot it will glow red, espically in the dark.

Engine running very rough and exast under car very hot.


DISCONCT THE EHXAUST BEFORE THE CAT AND ROAD TEST.
A GLOWING CAT HAS MOST LIKELY FAILED.
BUT LOOK FOR OTHER PROBLEMS THE MAY HAVE CAUSED THE CAT TO FAIL.

No get up and go


is the trannie a 4l60E? if so the ranine is going out, if it revs high and you dont notice the increase in speed like it should, the trannie is slipping this particular trannie is known for this its junk, chevy should recall them all and pay us for the headache.....Another issue could be that nasty cat-converter.. away to check is to tap on it, if it sounds rock solid it clogged need to be replace, or after driving for an extended amount of time, when you park the ceh, look under it to see if the cat is glowing red....if so its the cat...let me know about thses thing and we can go from there ....

WON'T KEEP RUNNING


Check the exhaust compression. Remove the O2 sensors before the cataylic converts and see if it improves. If it does that means your cats are cloged and need to be replaced.

Had the same problem last year with my truck. It was the MAP sensor. Mine was on the far left hand side of the fire wall Or passenger side. Should be one vacuum line going into it. unplug it and try firing it up.it probably wont run perfect but better. I went to a scrap yard and picked one up for $10. (They let me plug it in first to make sure that's what i needed.)As soon as I plugged it in the truck started purring like a tom cat in a dairy. If your into the scrap yard thing than its not an expensive experiment. Not sure if this is you problem ( My crystal ball works about as good as anyone else's) but its a suggestion.
