Hi Jay,

I hope you are right, but it doesn't make sense to me that the throttle body gaskets would only be a problem when the engine gets warm. Your dealer should have replaced them if they even suspected they might be bad when you had it in. Gaskets are cheap and easy, so I guess I'd say replace them for peace of mind, if nothing else.

You would really be doing yourself a favor by getting all of the freeze frame data from the computer when the light is on. It often has invaluable information to help troubleshoot the issue. I'm thinking the Autozone guys can get this for you if you stop in there when the light comes on.

In any event, I think 46davis has a great point. For that kind of money, I'd be right back at that shop's doorstep having an intense conversation with that service manager. There needs to be some kind of effort displayed to make it right on their part.

Hi Jim,
I talked to Autozone & got a bewildered look.
That was mentioned to someone who used to work there & he said that was not a surprise.
Thank goodness I have a ScanGuage II in my car!
He suggested using starter spray to track down the leak.
I am going to try that if it ever dries out here.
The error's did came back again, it has been really humid here (70 -100%) & only about 75 degrees.
The engine was also at operating temp.
That definitely shows a vacuum leak.
Also there are a couple of days available for me to track down that Service Manager.
Thanks for the reply!

Hi!
I think I may have isolated this issue?
The short PCV Vacuum hose at the air intake end is rotted & cracked.
Hissing can be heard while the engine is running.
Does that sound like the issue?

Rotted PCV hose on the pre 04 Tec is a well known issue that causes poor idle, missing, etc.

Sheila called it very early.

And sorry to say it like this, but in the San Francisco Bay area, where used cars are not cheap, you could have bought a 99 with the DOHC for less than $1600. I bought the one that I have now, 99 wagon, DOHC, three months ago with 106,000 miles on it for $1100. There was 6-8 I was looking at all under $1500.

A talk with the service mgr, maybe the GM, and if needed the regional rep is definitely called for. If no money back they need to credit you some service.

Hi!
The picture Sheila posted looked like it was under the throttle body.
The only reason I found it was my Neutral Safety Switch went bad.
Removing the Air Cleaner body showed it.

Hi!
I got hold of the Ford Service Manager!
I went over what I paid & what I found.
He sounded a bit dumbfounded by the history of repair on my car.
He said he would talk to the tech & call me back.
I also mentioned that I have a starting issue that now points to a fuel pump.
It was already replaced by them in August, he said it was still under warranty.
We shall see what comes of this.

Hello!
I did replace that short PCV Hose.
It is weird that I found a package at the local Fleet Farm with some funny shaped hoses marked Ford.
Now my OBD II errors have gone away!
Thank you Sheila!
I am calling that Service Manager tomorrow!
