Just wondering how necessary the egr system is and, if not, how to get rid of his. I get my service engine light on and its a code 32 for egr system and i replaced the valve to no success. before i go blow 80 bux on a solenoid id just like to know if its easier to plug off the whole thing. i live in florida and there is no inspection of any kind.

I can almost garuntee that the solenoid is bad. The way the ECm decides to throw a light is that it turns on the solenoid, then look for vacuum at the little sensor that is teed into the EGR vacuum line to the egr, from the solenoid.

Something else you can do is check the sensor itself. It's a MAP sensor, but it doesn't use it for Load calculation, just to see if the solenoid is bad. Most of the time, it's not the sensor, but the solenoid that's bad.

Just taking off the EGR system won't solve your MIL problem unless you reflash the PROM. You'll have to get a custome chip burned so that you don't have the EGR diagnosis stuff in the computer anymore.

Removing the EGR will cause 1)Higher NOx emissions, but most people could give a crap about this, and 2) will likely make your vehicle ping a lot. EGR helps to reduce combustion chamber temps, and therefore helps to reduce detonation.

By removing the EGR you do gain easier access to the passenger side of the engine though. That's it.

Hope this helps,

Don't laugh but
You sound like it needs a cleanup
Remove the EGR & see if filled with crud at base.
Check your hoses too
Reconnect & if I read right you already purchased a new EGR. Stick it back and & you should be better.
EGR mission not that difficult.
BUT IF NOT NEW EGR go get a new one, they like $30

The valve is new and was put on a few months ago. could a leak in the exhaust in that area cause the problem? also when i come to a stop the rpms drop below 500 and come back, is this being caused by the egr system problems?

also, the error code is not constant, it comes on after driving for a while.

It could be a vacume leak from the vacume line going into the egr that could cause it not to open up.
