Engine has no power going up hills?

What is the procedure to change the fuel sock.
The vehicle loses power after half throttle. Catalitic converter was plugged but is now free but this problem still exists. I suspect the fuel sock needs replacing. Is there any other possibilities? Thank you

Engine Mechanical problem
1998 Dodge Ram V8 Four Wheel Drive Automatic 150,000 miles.

I have a 1500, 5.2 litre. The problem is under normal driving condition, the engine losses power and starts popping like a popcorn popper. It will continue with no power and popping until I accelerate and the transmission kicks down, all power is restored and noise is gone but will continue to re-occur. I checked the timing due to a TSB about the gear under the distributor wearing out, but it checked out fine. There are no codes stored. I almost think its a fuel delivery prob.
I read your other suggestions on popping and you guys stated fuel pump. I spent the $300.00 on a fuel pump module, changed the plugs, wires, cap, rotor, air cleaner and ignition coil and its still doing it. Any suggestions?

I have the same truck same symptoms. Popping is in the exhuast. Fuel pressure remain 50lbs. --O2 voltage drops to.02. Pcm does seem to respond with more fuel. Problems are completely intermitent
new parts. Pick-up coil, cap rotor wires, intake bellypan gskt.
I'm thinking bad PCM. Looking for a way to confirm

The popping is definatly through the intake. I checked the timing with a gun.

After spending good money after bad, and changing half the parts on my engine, it turns out that I had a bad O2 sensor. Dodge and there wisdom decided not to let the computer trip the check engine light when the sensor fails. So anyone that experiences the symptoms that I have described above, try changing your O2 sensor first.

I turn my truck on this morning and the check engine light came on. This happened three days after I went to Autozone for an OBD reading and the guy said he could not read the truck, but the light went off after the scanning was done. Now that it is back on I noticed, a hissing sound when I push the gas, no acceleration until 2500 rpm, and rough tachometer. To me this sounds like a vacuum leak, but do you think it could be something more?

My 2001 dodge starts right up runs a little rough and runs fine one day and may stall at a light the next. When it goes to stall I put my foot into it and I get the popping noise, but not all the time. Is this the same issues you were having?

Not the issue I am having. My truck shut off when I had pushed the resume button for my cruise control and now it won't restart.
