Finally I brought the car to the mechanic. The problem was the exhaust, it was restricted or something like that. They replace the catalytic converter and after 327 dollars the car is running great again. Thanks for the help.

Glad you finally got it sorted out. If your car is running great now, then it was worth the effort and I'm sure you've learnt a lot in the meantime. Good luck in the future.
that's what Im talking about! Good job. driving is a great experience when your car is in the right conditioin. The $$ was just about right. My replacement was about the same but I had to have flanges welded since my old cat was welded to the pipe. If it was not, I would have installed it myself. It actually hell working below a car when you dont have a lift

A vacuum gauge on the manifold would've indicated a clogged cat, as well as a pressure gauge temporarily plumbed into the O2 sensor hole. And either one would've shown the problem easily within a minute of starting the engine. Any GOOD mechanic should know that. Don't get me wrong, I'm glad for you that the problem is fixed, I just fail to see how it would take 10 minutes for the problem to rear it's ugly head. I get the whole 'backed up gasses tripped the O2 sensor towards the lean side causing the ECU to pump more and more fuel until it was blubbering rich and stumbling' thing. Again, it's the 10 minutes. I would figure the engine would start running like crap within 1 or 2 minutes, not 10...
They took out the O2 sensor and the car start to run much better. After it is fixed looks very easy, but I'm not a mechanic.
I did learn a lot from this problem.
Thank you very much for the help.
Ya know, I just noticed something about the title of this thread...
'97 Sentra Jerks...
--conversation the day after a big car show---
"So, how many of them were at the car show?"
"There was 97 of them, all of them with Sentra's."
"Yep, that's what I thought. 97 Sentra Jerks."

I saw that too but didn't comment on it. As soon as I have the funds Im getting sr20det and run everyone off the road!!
just wanted to post that a distributor swap resolved my jerking issues (ty junkyarddog dot com for the $87 replacement). this was unexpected because both the cap and rotor were less than a month old.
the inside of the cap was carbon-caked and the rotor itself was loose.. which was very odd.. since the screw holding it was still tightly in place (thanks to the thread-lock glue we used when installing it). somehow the hole in the rotor which the screw passes through had widened into an oval allowing it to slip around. weird huh?
after taking the dist. apart we saw the inside was carbon-caked as well. any ideas how this might have happened?
i dont think most people realize what a blessing it is to have a motor that delivers a smooth power output throughout its powerband
it can be pretty frustrating driving a car that bogs, sucks all the fun out of driving...
finally got my issue resolved though, thank God...
turned out that the valve cover was not seated properly after a change of the valve cover gasket and so
the little rectangular seal under the valve cover was not seated properly and so
oil was sucked in through the pcv valve in large amounts producing huge clouds of smoke, along with, of course, the horrible bogging i was experiencing.
since the valve cover gasket was replaced along with the small rectangular seal under the valve cover, the car has been finally driving well once again.
