SOURCE: Difficulty to replace EGR valve in 1999 totyota camry 4-cyl automatic

If you have small hands it can be easy. The space between firewall and EGR is tight but it wasn't too difficult to remove. The vacuum hose at the bottom was hard to pull off and I ended up cracking it and had to splice it. It was more difficult to re-install the EGR then remove it. I had a difficult time with keeping the gasket aligned while bolting it in to the lower tube. I took a few attempts. I suggest when replacing the EGR leave the mounting bolts loose so you can more easily align the metal tube. I would tighten the metal tube at the bottom of EGR first then tighten the upper two mounting bolts on top. It took me about 5 minutes to remove and 15 minutes to replace. I would be sure to clean the IAC too after cleaning the EGR. I sprayed throttle bottle cleaner down the bottom hole located on the throttle body and let soak about 15 minutes then start and run the engine a minute and repeat the process. This helped smooth the idle while stopped at a light. It also stopped the idle from shaking and almost stalling the car out at a traffic stop when the engine was warm.

SOURCE: 2000 Honda Accord EGR Valve Error P0401

Jason,
-after you change the part you have to reset/clear the code

-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete all codes/radio presets/etc) but it will also clear the 'check engine' code
-this is what I do AFTER i write down my radio station presets :)

-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also

-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works
thanks

SOURCE: how to replace EGR valve on 99 Chevy Tracker

Take off your EGR valve and clean it out with carb cleaner also
grease tyhe little screw thing in it,,, u will c what i mean if u take it apart. carbon builds up in the chamber. it is located at the back left side of your engine and is a bit of a pain to take off. this should save u the cost except for the cleaner and labor. i had the same problem cheapest i found was 90$ on ebay.

I repair mine last summer,
It is on the exast port, left.
You have a tube attach to it, going in the Head Cover.
Easy to change. it cost me $105.00CND at the dealer

Good Luck

SOURCE: EGR Valve needs cleaning or replacing

The link below is a diagram of the EGR valve. Looks like a mushroom with vacuum lines attached.

http://www.chiltonlibrary.com/content/images/8666/images/86664018.gif

Instructions:

  • Label and disconnect the hoses from the valve. Carefully loosen and remove the retaining bolts, remembering that they are probably heat-seized and rusty. Use penetrating oil freely.
  • Remove the valve and clean the gasket remains from both mating surfaces.
  • Inspect the valve for any sign of carbon deposits or other cause of binding or sticking. The valve must close and seal properly; the pintle area may be cleaned with solvent to remove soot and carbon.

  • I hope this answers your question. Best of luck.

    Replaced ignition switch/key/ security module on 1999 saab 9-5 now won't start, will turn over


    It surely does. If you got the key,switch, and module fro one car. Go back and get the engine control module. This will work also. But beware. The engine module must fit you engine and transmission. Also beware. Some security modules are one time only program. Meaning, you have to buy a new one and have it programmed.

    Hi you really need to get the trouble codes read out the engine ecu but from experience the most likely cause is the EGR valve or throttle body.

    This is usually the first (cheapest) place to start. The MAF (mass air flow) meter is designed to sense and adjust the vehicle engine to changes in air temperature, speed, density etc. to keep your vehicle running properly. Since you already had your EGR replaced (yet another possible source of this sort of problem) I would tend to lean more toward the MAF. If you run any sort of aftermarket intake such as a k&n etc. these can cause problems for certain vehicles that are very sensitive to air flow as Saabs tend to be. Also the oil used on filter elements such as k&n can ruin the sensitive MAF. This unit is generally easy to fix (it's the little box with wires running to it) mid way up your air intake tube just past the filter. They aren't too terribly expensive either. Try this and hopefully this gets you up and running.

    Saab 9-3 engine into 9-5


    the engines are different model engines since they run off the computer im thinking that you need to set the computer to the 9.3 since the specs run the 9-5 at different frequency the enigine modules still think its a 9-5 in which you want the computer to run it at 9-3 this gives the high throttle reving

    you need a laptop and your cars software to set the idle control for vehicle and possibily the proper idle control module for engine
