95 camry stalling out problems - EGR valve?

[amystoys]

My son is driving my 95 camry and is having problems for last 2 months. After he had been driving for a couple of weeks he started having problems with the car stalling when stopped but could normally restart and continue. He discoverd a crack in the air intake hose and we replaced that at Thanksgiving when the car broke down while traveling home for the holiday. It was driving okay until he exited off the highway and cut off at the exit ramp light. He got it started and went to a gas station and it stalled out again. After waiting a while he was able to start again and continue but when traffic got backed up on the interstate and he was in slow-moving traffic it was stalling out and he was having to give it more gas in neutral to keep it moving. After replacing the air intake hose it stalled once again and then traffic picked up and no more problems. He took it to a mechanic who could not duplicate the problem and ran diagnostics with no indication of a problem. A week later he has the same problems again. Mechanic replaces ignition module and spark plug wires. Car seems to run find but a week later he is having the same problem. Could this be the EGR valve that needs cleaning?

I am having the exact same problem with my 95 Camry and two garages have given up after replacing electrical system parts. I'm tired of paying people to not fix it when they "fix it" I've researched a bit, but I'm coming up with nothing. Any ideas from more experienced people would really be appreciated. Some things we've looked into on our own: a sensor issue or a valve in the vacuum that adjusts the idle. Okay to start initially, but once warm, gotta keep the accelerator depressed or it dies. Starts again, but driving 2 footed. Going on for months.

I have asked my son to request the mechanic clean the EGR valve before he gets it back today (hopefully). That is the only thing I have found in this forum that seems like might be the same problem we are having. So if you are still having problems; get the EGR valve cleaned; (with brake cleaner, I think) and see if that works. Can't seem to get any other replies from a mechanic that actually might be able to give some good advice; but I'm still searching the internet. Good Luck!! I'll let you know what happens with mine.

Try cleaning out the throttle body with some injector cleaner and a tooth brush. You can by kits ( intakesnake.com) or have it done.
Put in a new PCV while you're at it.
NO guarantees - but -
my 94 had this problem and now it runs sweet as can be.

a camry 95 deserves a EGR cleanning anyways. If that soles your problem great. Another one , quite tricky, is the temp sensor malfunction. This is an erratic one, but tends to happen as a warm stall or any time when the coolant temps gets high (idling during heavy traffic). This malfunction rarely turns the engine problem light signal. Best way to check? Connect an ohmeter to the temp sensor, start your car and let it idle. The ohmeter should give you values of 20-40 K ohms when cold and 0.2 Kohms when the fan starts after idling. Keep an eye on the meter. If it start jumping from 0.2-9 kohms to 80-200 k ohms, change temp sensor. With this high k ohms readings the temp sensor is telling the ECU that coolant is cold and go send morw gas to the engine= warm stall. Check my galleries there is picture with three switches, the green on left is the temp sensor. good luck

Thanks so much for the info; I am waiting for the mechanic to get back to me; I think this might be the part he replaced this time.

I think it's your EGR valve. Just take it off and clean it out. It cost nothing to do. Your mechanic will gladly replace every damn electrical part and it still won't idle unless your EGR is clean.

An easy test is to drive the car until it starts cutting out, then have an assistant keep their foot on the gas to keep the engine lit (in neutral.) You go under the hood, and rap the EGR with a hammer until it comes unstuck (that's what's happening: It's stuck open!) If you can get the car to run normally after beating the EGR, then you know for sure.

I spent months one time, everytime it started stalling at a light, I would open the hood and smack the EGR with my special "EGR hammer" ONE time, and that was usually enough for a while. It goes just fine as it runs down the highway, right? Yup.
