Could be any number of things. Take it somewhere and have the computer read, which will give you the error code. That error code will tell you the area that is causing the problem. Many autoparts chains will read the error free of charge for you, and suggest what the parts are to fix the problem.

Burned/leaking intake valves.
Combusted gasses only leak back into the intake manifold and ignite the gas there (stumble..) with HIGH cylinder charge volume.

Help... Took my Camry in after the check engine light came on, dealer stated "need to replace right side air flow sensors and the manifold" based on the codes extrated... $1500.00. Car has 68,000 miles on it and runs like a top. Service manager states the air flow sensors are measuring the air and fuel mixture incorrectly (to lean).
Anybody heard of this? Can't find any info on this.... Help.

You are not providing enough information.
Did he tell you the error codes that the computer had in it?
You indicate that he is going to replace the air flow sensor AND the manifold....which doesn't make sense for a first time diagnostic problem. I can see replacing a sensor, I can't see replacing a manifold unless there was reason to believe it was cracked or a gasket bad found through other testing.
Get the error codes from him, or if the light is still on go to an autoparts store where they can pull the error codes for you.
Is he talking about the Mass Air Flow sensor, an Oxygen Sensor, or something else?

Hey thanks, I got error P0441. It says it is a leak in the VSV or bad charcoal system. How do you find out if you have a bad VSV. They all seem to be pushing air flow. However one is not??? Should they all be pushing air when you take the hose off?

You should look up TSB EG036-06. Your vehicle may be out of warranty, but some of the system may be covered by warranty. Don't know the VIN number of your vehicle, and whether this applies to you.
I tried sending it to clindstromcarspace.com, let's see if that works
You need to go to your carspace area, your toolbox, then mailbox section

Finally got the codes from the service manager,
He stated that these codes (P2195, P0171, P0174) had to do with the oxygen sensor's measuring "to lean", therefore sending data that more fuel is needed and the engine is burning more fuel and emitting more emissions into the environment than it should. He stated "Toyota's fix for this includes changing the O2 sensors and also changing the manifold to a newer style manifold which positions the sensors in a better position" I told him it is a very costly repair for me and he suggested an option of just replacing the O2 sensors with the style that is on there now for a cheaper option.
He said another set of codes also appeared (P0441 & P 0446) that deals with some type of air leak in the fuel system, but does not know if that has to do with the above mentioned problem that is all related.
Any thoughts would be appreciated. How difficult is it to change the O2 sensors on my own?

That is certainly clearer now. They are referencing the exhaust manifold, which is what bolts on to the side of the engine and captures the exhaust gases from the cylinders, and then starts to feed it down toward the exhaust pipes and catalytic converter. An O2 sensor sits before and after the catalytic converter, and the computer uses those engine output signals to adjust the 'input' fuel mixture.....to get a clean burning mixture.
O2 sensors do go bad, and are reasonably easy to replace. Personally, I would think long and hard about replacing the exhaust manifold.....they would normally last forever on engines, there is nothing to wear. I think I'd be calling the service manager and ask them to escalate to Toyota on your behalf. If there really is a new design manifold, and they are stating the old design is designed defectively, then I'd ask for Toyota to eat the cost of the replacement. I doubt that they'd do that, but I'd be asking.

Car ran lousey for a day then it stalled and would not start.Should I be able to hear electric fuel pump when key is in start posision?>

I doubt it, unless you have really good hearing. I've never heard a fuel pump for any of the vehicles we've owned over the years.
