My 2000 Jeep Wrangler runs great except for in the rain. If it's sitting outside in the rain it idles below 750 and has next to know acceleration until 3000 rpm. This problem usually goes away after about 10 minutes of driving. Does anyone know where to start with this?
The problem itself kind of sounds like a fuel pressure issue, but the rain thing makes me think it's an electrical problem...have you changed out the rotor/cap/plugs/wires recently and greased the connections well?
