2000 Alero Boggs down on occasion

My Alero boggs down on occasion. I replaced the plugs and boots. I also replaced the air filter. The problem is still there. I think that I need to replace the feul filter. Has anyone else had this problem? If so, did a new feul filter fix the problem?

    Yes, I can get up to highway speed. It takes a while to get there though. There is no check engine light on right now. I don't know what the EGR is. I had it put on a diagnostic machine and they told me that it was missing. I changed the plugs and boots and disconected the battery to reset the computer. The problem is still there.

    Yes, it does stumble when I am stopped. It is when I am stopped when it happens the most.

    Thanks for letting me know about the battery. I did not know that. I was told that would work. How do I get the code out of there, if I can?

  • hejohnson Feb 05, 2009

    Does the stumble mean that it is the EGR?

  • hejohnson Feb 05, 2009

    Thanks for all the help. I would never have known about the EGR. I will try it and see if that was the problem. Thanks again.

    Disconnecting the battery to reset the computer on these newer cars doesn't do any good anymore.  The older cars that would reset them.  But the newer cars have a memory and they don't "forget" the codes.

    The EGR is the Excessive gas recirculation valve. Does the car stumble when you are stopped?

    Can you get up to freeway speed? Usually if it is the fuel filter you will only be able to go so fast and then the car just stays at that speed or slower. Have you checked the EGR or is there a check engine light?

The way to erase the code is either take it to a local repair shop and they can hook it up to a computer and erase it, or most major parts stores have one to borrow.  You can take it and use it in the parking lot to read/erase codes.  Some parts stores will do it for you and some won't.  It just depends.
You should have an EGR, you can take it off and clean it with some carb/choke cleaner then let it dry and then put it back on.  Then if that fixes it you know you will need to replace an EGR soon.  Usually EGR valves are located on the top of the motor.  They have kind of a disk shaped thing on top of them.  A pic is below of what yours should look similar to (assuming you have the 6-cyl motor.)  The part will be approx $90 to purchase from a parts store. (Of course, prices will vary) 2000 Alero Boggs down on occasion - b79cf23.jpeg

Have a 2000 honda passport its bogging down when you give it gas its starting to do it all the time so u cannot pass any one cause it boggs down nd you dont have enough power to pass

Have you tried replacing the fuel filter? Bogging down is such a generic discription that it could mean with your AC on or off; whether the vehicle is running hot; etc. So I will have to go with the most common reasons which is fuel filter and fuel pump; followed by fouled plugs and plug wires.

92 Honda Accord boggs down when throttle is pressed at idle speed

try unplugging the egr vacuum source and plug the line and drive. If no difference you ruled out the egr as being the issue.
Please do not rate this solution since by not seeing the car and doing my own test there is no way to tell if maybe you just hooked up something wrong.

1988 cutlass ciera boggs down when i accelerate

Hello! You have symptoms that point to incorrect fuel pressure.
First have the fuel pressure tested as follows; #1...engine running at idle: 13- 20 psi. #2...key on engine off: 23-30 psi. If pressure is incorrect change the fuel pump.

Does the engine "surge" at idle? If so, check the "fuel injection pressure regulator idle air control valve". Apply a vacuum to it; If fuel flows it is not the problem.

I just got done with this same problem. Check a small looped vacuum hose just behind the mass air flow sensor which is attached to the air filter housing. the hose will be toward the plenom on the right side next to a blue connector. They have a tendency of getting soft.
