Starting really weak/weird idle points to low battery voltage or terminal connections. I'd eliminate the battery as the problem first. Since you have a '99 have to ask if the gauges are sweeping or trip odometer is resetting on startup? - another indication of low voltage.

Check the battery voltage. Check your air filter to see if its plugged. Wouldn't be a bad idea to change the fuel filter if you've never done that.

Default fuel pressure

Check you're fuel pressure. If its low it might be the fuel filter or fuel pump. I had this problem and I needed to change the fuel pump at 88,000 miles. So if u have 128,000 and haven't changed th pump, there is a good chance it might be that.

I'd start with your fuel filter. Then probably the pump.
