Did I st-t-t-t-tut-t-t-t-t-ter???????????
Let them try to tell you whats wrong with it????????
Unless you have some super autozone where you live, all they're gonna do is pull the codes and say it's the o2 sensor. He's already done all the basic stuff and knows the codes, autozone can't do anything for him. I always hear about ya'll chicago guys' cars having problems, mine seems to be doin just fine though... hmm what do i know though.

Now that you mention it, last week the snow began to melt and when I parked my car in the garage one night, I heard a hissing noise. I figured it was my front left tire because it had a very slow leak. But looking back, at the rate it was hissing, my tire would have been flat by morning. This hissing happened on two occasions, both wet road conditions.
Is it possible that a hose is cracked or disconnected and the water created the noise? Would a leaky intake gasket make the noise? My tire will stay aired up for a couple days before it goes flat (I need to fix it soon), so I suppose it wasn't the tire.

That hissing noise you heard has nothing to do with the codes you posted.
The conditions you described mean that there is unmetered air going through the system. That means you have a vacuum leak somewhere. A can or two of intake clener spary, sprayed on the intake and vacuum lines, will aid in pinpointing it.
I ordered the parts a few days ago to perform an intake rebuild on the wife's car. Exact same codes but runs fine. The spray indicates a leak in the infamous intake gaskets.
Probably start mine Tuesday or Wednesday provided parts arrive on schedule.

What exactly is intake spray?
I will definitely pass this advice on. Should this be the problem, what kind of repair and what cost will most likely occur?
Any other ideas anyone?

Use starter fluid to track a leak down. Depends on what is leaking and if you can fix it yourself as to how much it'll cost to fix.

Well this morning after work I stopped down at the shop and talked to the head mechanic about what I learned on the internet with vacuum leaks, etc. He said he had already done a good check for this.
When I got home I did the starter fluid check anyway. When I sprayed in the vicinity of the PCV valve (behind the throttle body) I got a slight RPM increase. I found a nice little 1/4 inch cut in the hose that leads to the PCV!  Put my finger over it and the car almost died. Took the hose off and getting a replacement today. I'm hoping this is the problem.

Wow, that's really weird. I also found a cracked PCV valve hose when I recently did the intake rebuild. I had the infamous P0171 & P0174 DTC codes so I ordered the intake rebuild parts from Bill Jenkins and did the rebuild just before Xmas. AFTER tearing the intake system apart I found a crack in one of the PCV hoses going towards the firewall. Very suspicious.

Yep, the one going to the firewall. The hose I pulled off is about 4-5 inches long heater hose. I just did the repair yesterday, so I have yet to see if this solves the CEL problem. I really hope it does. Did you replace your cracked hose?

Yes, I did replace this 3/8 inch rubber hose. This hose attaches to the PCV valve and another hard plasic hose which goes somewhere near the firewall. I went to the stealership thinking it was a special hose since it had a slight bend, but the parts guy said it wasn't a Ford part. I think it was damaged/cracked by a "mechanic" when I had my precats replaced in March 2002 ( don't ever let Midas work on your car ... long story). During the intake rebuild (Xmas 2003) I noticed a 19mm socket resting on the ATX. I think it fell down there during the precat repairs and the hose was damaged when somebody tried retrieving the socket. My CEL light came on around August 2002 with P0171 DTC.
I'll keep my fingers crossed for ya.

Too late.  On the way home tonight (jan. 2) the cursed CEL came on. My PCV hose repair wasn't the answer I guess. My hose was in very bad shape (cracking), so I think the shop mechanics probably caused the cut when they were taking stuff apart way back when. Oh well, at least that hose is out of my way.
Well, I guess I better get the starting fluid out again and do another check. I must say I'm not in the mood to do an intake rebuild. I am very capable of doing the repair, but I'm busy the way it is.
I'm gonna give the Ford dealership a chance to find something wrong, after that I'm gonna consider the rebuild.
I hope you have good luck with your repair!
