Not a chev but i need help on the work truck This is for my work truck, 1995 dodge 2500 with a 5.9L 360.
NEW
Plugs
wires
cap
rotor
TPS
CLEANED
TB
IAC
Runs rough and has no power, the warmer it gets the worse it runs. Burned a 1/4 of fuel in 30miles. No check engine light, does come on when I turn key on. Checked for codes anyway and no codes.
Thanks for any help.

O2 sensors?
On a 1995 you do not have downstream O2s so you will not throw a code for an O2 sensor that is bad, but functioning.
Next up is a clogged cat. Look for signs of overheating. Is the cat bright red when you first park, is it discolored, does it rattle? A bright red cat is caused by too much unburnt fuel or a worn out catalyst.
Also check for bad, dirty or stuck injectors.

Thanks for the reply.
I was thinking the same thing but wasn't sure. Now that you mention it, it does run a lot hotter than it use too. I will have to check out the cat and see if it is bright red or discolored or rattles.

Bad 02 sensors will make it run very rich and stumble and lose power.
If it started all of a sudden though:
You may have one or more fuel injectors that are leaking or maybe the atomizer screen has worn out or popped a hole and a shitload of fuel is dumping into one of more cylinders. That would explain the bad gas mileage.
I've seen this a few times. I think one was actually a Dodge Hemi truck. He lost a ton of gas in a very short time too. It was just spraying like a hose into one cylinder. He found it, replaced it and it was fixed.
