EGR Systems
When the temperature in the combustion chamber becomes extremely hot, nitrous oxides are formed, which then turn into smog. In order to reduce such occurrence, the exhaust gas recirculation system minimizes the temperature in the combustion chamber.

Answeryou may want to adjust the automatic choke and set it out side of the factury setting and readjust the high idle speed setting. you may need to drill out the rivets and set the choke to a richer setting. this worked for me. I have 85 z24 engine.

AnswerOn the back of the carb is an idle stop solinoid that shuts off the air flow through the idle passage way. I have found that the passage way can be blocked with dirt. Remove the solinoid and spray carb cleaner in the solinoid hole then blow out with compresed air. Be sure that the rubber O ring for the solinoid comes out with the solinoid and is not stuck in the hole first. Also check that there is 12volts going to the solinoid when the key is on the run position. This is somtimes fed through the alt. fuse.
AnswerLoose Hot Wire to control box for electronic controlled Carburator.
Ok all of these answers have probably been wrong. I just had the same prob with my truck and i have found it was a vacuum leak. If you can hear a vac leak than its probably your prob. If not then dont waist your time. Anyways on the side of the carb there as a hose that travels to the top of the truck. It connects on the left side of the carburetor kinda towards the bottom. My truck was doing the same thing and it turned out to be a split hose. I did not hear the leak until after a couple of days of driving it but as soon as i found it then it immediately ran 100% better. Try this and see. If so let me know. junk that factory carb. and get awebber 32/36 carb.Where is the EGR valve on a 1999 Pontiac Firebird?
The EGR Valve on a 1999 Pontiac Firebird is located just to the left of the engine oil dipstick. There's nothing in the way so it's pretty easy to get to and replace. Hope this helps!

What does a P0404 exhaust gas recirculation valve look like?
They all look different, depending on the model of the car. If you are curious, look up the part online at any auto parts store. This way you can see what the EGR valve for your specific vehicle looks like.
Where is the EGR valve located on a 1997 Lumina 3.1L and is it hard to replace?
If your standing in front of the car it is just to the right of the ignition system (where all the spark plug wires are). It's round and it has a line that goes to the intake hose just before it attaches to the aluminum intake on top of the engine. Being that the EGR is on top of the engine it shouldn't be too difficult to change, but I can't say for sure because I haven't done it. It's easy. All you need is a 10mm socket, 2" extension, and ratchet. Unbolt unplug and you're done.
How much does it cost to replace a stair?
It really depends on many factors. Say for example you want to replace an exterior wooden stair such as one on a deck. Lets assume it is 8 or 9 feet high. Assuming that you are not going to deal with pouring a concrete pad for the foundation of it, you are probably looking at about $2000 or maybe $3000. Now lets assume that you want to replace a staircase inside a home. Again many factors shape the total cost. If is is a simple stair such as one that is going to be covered with carpet and instead of balusters or spindles a "pony wall" with a cap will be used instead o a handrail you can expect a similar cost as that of the previous example on a deck. How about if you want to go fancy? Maybe a "post to post" or "Over the post" railing configuration, maybe also you want an "Open stringer" to show off beautiful miters at the union of "risers" and "stringer", so as to show off the beauty of hardwood "bull nose" treads. Obviously here you are talking about more expense. Maybe around 6K. Get a reputable "stair builder", ask for references and you should be ok. If you are thinking about doing it yourself, Don't. You will be better off trowing your money away (if you are not skilled enough). At least you wont have to rip it out.

How do you test a dodge egr solenoid?
ok, here is a preliminary test. get an ohm meter aka continuity tester, unplug the solenoid from it's plug style connector. Look inside connector and you will see metal contacts or prongs. Plug your continuity tester leads on the metal prongs. continuity should be complete , another test that can be performed is to connect a 12volt power source up to the solenoid.......this will cause the mechanism to operate and the solenoid will "click" and do it's thing. good luck
