Maintenance/Repairs

I have a 1994 Jeep Grand Cherokee Laredo 4X4 4.0L 6cylinder with 125k miles. First, my Jeep idles at around 200rpm (the first line on the tach.), is this normal? I have had the Jeep for almost 2 years and it has always done this. It has not been a problem in the past except when it got below zero. Then at stoplights my Jeep would sometimes stall and I would just have to restart the engine.

This was not a big issue until a few months ago when my Jeep started with intermittent starting troubles. I can get my Jeep to start on the first crank the first time I drive the Jeep that day or if the Jeep has been sitting for at least 4 hours. For all subsequent starts that day I have to crank the Jeep from 5 to 30+ cranks before the engine will turn over and start.

To begin with I had the starter replaced when I got the Jeep 2 years ago. At first I thought that it might have been a problem with the fuel system since the engine does crank and ultimately turns over. So I replaced the fuel filter and then the fuel pump with no change in condition. I also had the spark plugs and the distributer cap replaced again with no change in condition.

I am not sure what to do next. I am tired of sitting in parking lots with people looking at me while I crank the engine over and over before my Jeep starts. Any ideas on what to do next would be greatly appreciated.
