1988 jeep wrangler idoling rough

I have an 88 wrangler and it idols rough and stalls out after driving down the road and stopping at a stop sign. It starts back up after stalling out. I changed the plugs, cap, rotor, and wires and fuel filter. Also does anyone know how i can get a schematic on the vacuum lines for this jeep.

It does sound like a vacuum leak. Get a can of WD-40 and start spraying around the carb. It will rev up, and U can pin point the loose vacuum hose, are crack vacuum hose.

    You might want to run a tank of supreme gas, plus a can of SAEFOAM in the tank as well. You might a O2 -sensor fauled out causing this problem as well????
