96 Jeep Grand Cherokee Laredo replaced fuel filter and o2 sensor but still having stuttering like no fuel after sitting at light for awhile or during stop and go. After babying it a bit I can get the rpms up enough so it catches at about 45mph, but still chugs a bit til about 60mph. Can't drive everywhere doing 65! I guess I'll be driving fast til I figure it out. Help! My license doesn't need these points!

Start at the fuel pump and work your way up to the injectors, spark plugs, wires and distributor. I recently had the same problem on my XJ. I replaced everything from the rotor to the plugs and after a few miles it went away.

You may be better off in the Grand Cherokee forum. You said you replaced the O2 sensor, which one? The upper or lower and were the symptoms exactly the same before hand? The upper O2 sensor made my XJ sputter and buck intermittently without throwing a code, it was aweful. Unplugging the O2 sensor makes the computer run in a preset mode but will throw a code. I unplugged mine to verify it was the issue. Aside from that I would go with plugs, wires, dist cap, rotor and possibly coil. Could be the Crank or Camshaft position sensors too. This type of issue is not fun. BTW, are you getting a code now?
