2002 Camry XLE V6 3.0 stalling problem

[vanessak55]

First, I'm new to this site and not quite sure how to get answers to my questions, so thank you in advance for your patience.
I purchased a used 2002 Camry [above model] with 99K miles on it in March, 2009. This is my 3rd Camry as the first, 1986 had 256K and the 1997 had 252K. I was very pleased with the 86 & 97 and very DISPLEASED with this new one!
I have problems with the enging stalling, surging at stop signs as well as problems at about 40 mph.
Any help will be appreciated.
Thanks

Thanks for the info. I replaced the TB in June because 2 weeks after I bought the car it started the surging problem. Spark plugs are 15K old. Someone on this forum suggested it may be the EGR position sensor.

check the egr vavle, clean it, or the IAC, might be dirty

Check your thread in the Intro section, i answered your question there

I have your car. you probably know by now there is no IAC valve to clean so that isn't it. I tried cleaning my egr once, still on the car, for preventative but not sure i accomplished anything, i think you'd want to disconnect it to soak it good in solvent.
You're on the right track, sounds like it might be an egr valve problem - they can go bad gradually and still never even turn on the CEL. Cleaning the EGR is worth a try before buying a new one because they are $214 (napaonline).
The usual quick and dirty way to test the EGR is to idle the engine, then reach under the valve and push up against the membrane - the idle should change. If it does not, your egr valve may be bad.

I've never cleaned the EGR properly but maybe a search will find a post by somebody who has.

also try cleaning the MAF sensor (carefully, its delicate - dont touch just spray).

also notice the little device that controls your butterfly inside the throttle body area, the horse-shoe shaped plastic thing - its a little electric motor not sure what he is called. This part could be bad also as it affects idle. It can be adjusted if you're desperate, (pm me if you want to try it and i will tell you how), but it's probably better to just test it - (im not sure how but i know it can be done with a VOM)

^ That's basically what i said in her intro thread.

You can also knock it with a hammer to loosen the carbon but it's only a temp fix.

I got mine OEM brand new for 140 i believe online.

Thank you for the information. I went ahead and had the EGR Valve replaced last week. I don't know if it will fix the problem, but so far, so good. I was also having issues at 40 mph, felt like the car was cutting out so my mechanic definitely said the EGR valve should be replaced.
I find this VERY frustrating when they can't pinpoint what the problem is!!!
As mentioned before, this is my 3rd Camry and I'm not very happy with this model!
Thank you again!
