Well here's th deal. I bought a 94 jeep about two months a go from up north. I drove it around a little while and once I saw that it was dependable and after I fixed the the computer I decided to rebuild. So I tore it down to the chassis and started buy parts in better shape. Tub, fenders, wheels, hard top, soft top, full hard doors, full soft doors, and and half hard doors. I did a full rust restoration on frame. It wasn't in bad shape. Just the body was. Replaced intake/headers gasket. Had headers welded up on a crack. Had all eahust rehanged. New o2 sensor as well. New shocks. Changed all fluids. New air and fuel filters. All new distributor, plugs, and wires. New coil. New battery. I redid all my grounds. Also I should mention its a 4.0 5 speed. Anyways so I got it all back togather and now its on the road. It was driving great but then it started to bog down a little then it got worse. Now when I crank it up it idles ok but as soon as I touch the gas it note down like its being flooded. Or the opposite. The motor sounds like it really working but its only turning like 1500 rpm. I can nearly get it to drive now. I made sure the gas was good but still no luck. What does that sound like to yall? I checked to make sure I didn't pinch any fuel lines. Plus I've got fuel pressure. No codes are showing other then12, 33, and 55. Are there any ways to test some of the sensors such as the IAC or map? Could it be the cat? I just wouldn't thank so because it appears to have already been replaced plus the jeep only has 116,000 miles on it. Thanks in advance for the help. I will check often in case yall need more info.
