Is the fuel pump turning on, and pumping fuel? Does it have electrical power?

yes, the fuel pump turns on (I can hear it), so it's not the fuse or electrical. Now, I don't know if the pump is actually pumping or if the fuel filter is allowing fuel to get pumped.

If the air duct from the air filter has a crack, it screws up the mass air flow sensor readings and runs poorly.
 
 I'd remove it and look under it for a crack along a seam on one of the ribs. A squeeze test of this duct while running, will cause it to stall out.
 
 Dont buy a Mass Air Sensor till your sure it is bad. I bet if you disconnect the Mass Air Flow sensor it will still run. Some cars computers go into default and will still run on the default settings if it senses a malfunction in the Mass Air Flow Sensor.

MPG on a 2007 V6 XLE Camry by djm2

Good Morning All:
 
       I just returned from a road trip to New York State. I traveled at 70mph on the NYSTW, and the vehicle got 31mpg! ---- This was achieved on 87 off-brand fuel. ---This is OUTSTANDING for a V6 engine.
 
       On entering the highway from a rest stop, I accelerated "hard" to see how this vehicle would perform. Within seconds it reached 80mph! ----- The shifts were smooth and positive. (The vehicle peformed like a "ROCKET"!) This vehicle could easily cruise at 100mph! (I would love to try this for about 1/2 hour somewhere if "RADAR" was not an issue !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!)--------- It is truly a road car! --- (Life was more fun years ago without road radar.)
 
      Best regards! ------------------- Dwayne

1997 Toy Camry fuel problem by clindstrom

I have a 1997 toy camry with 256K on it. It is a 4cyl. It will start and run great, however when you give it gas it chugs and close to stalling. When you give it gas slowly it will not chug, well just not as much. When you give it gas it is very slugish. check eng light came on. Could this be a trans or fule system problem? What could be doing this?

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.

...256K........
 
Burned/leaking intake valves.
 
Combusted gasses only leak back into the intake manifold and ignite the gas there (stumble..) with HIGH cylinder charge volume.

2007 Camry XLE V6 Air Flow Sensors, Manifold by skoman1

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?
 
Thank you!!!!!
