Thanks, I forgot to mention that the guy that changed my intake gasket checked the fuel pressure at idle and it was Ok. He did not check it while driving (I guess he didn't have the right tool for that).

Another thing that i forgot to mention, the problem seems to be less evident the colder it is. On cold mornings, if i get in and drive to work (about 5 miles), its not so bad until everything warms up to normal operating temp. But last week we had a few below freezing days and I would have never guessed there was a problem at all. It drove without any problems whatsoever.

I'll see if I can find someone to check the fuel pressure while driving but in the meantime, I'm still at a loss here.

To anyone else watching this post or for future viewers...

It turns out the problem was my catalytic convertor. The part was about $210. I was prepared to have the fuel pump replaced when the mechanic took it for a spin and advised against that. He commented that the fuel pump usually stops working all together so I wouldn't have even been able to drive the car in.

After replacing the convertor, the car ran like normal again.
