Q: what would happen if valve was not adjusted right? and please explain: www.okorder /

Q: problem seems like a bad IAC valve - When I start it, it runs at 2000 for 10 sec then starts varying between 1000 2000 rpm at idle. Over 2400 it is level. If I pull the connector it will vary quickly around 1500 rpm as soon as it is started. Cold or hot no difference. 10 sec delay will happen every time it is started.I just replaced the air cleaner and cleaned the PCV valve, which seems to work about the same as a new one, then this started. Coincidence or something else wrong - like an air leak? How can I be sure it is the IAC??I've pulled the air intake and plugged the bottom throttle port and it goes to idle. the only trouble code is 0505 unless of course I pull the connector. Pulling the throttle position sensor plug yields a constant 2000 rpm and an code indicating it is open.thanks.: iac valve common to fail on odysee also has problem with the wires to the power steering pressure switch pulling out of the connector causing idle to fluctuate lightly pull on wires to check for bad connection switch is in the power steering pressure line pass. side of car on back side of engine

Q: We need to replace our erg valve, but we cannot locate it.: I have that very vehicle and have had to locate mine, it is on the passenger side of the engine towards the firewall and it has an 5 pin electronic connector (Mine is Black) on top of a dark grey to black colored cylinder next to the cover on top of the engine. But before you go through replacing it (as it is around $200 to $300 ) try cleaning it with spray type fuel injector cleaner and work the stopper inside in and out until it frees up. This will need to be repeated as the faulty item in my vehicle was an o2 sensor of which there are 4 located throughout the engine. So you will need to have a decoder to check and see which is to blame. Most parts stores will read it for free. Good luck. P.S. my o2 sensor cost about $60 for the part.

Q: Movers messed up the valve so hose won't screw in w/o leaking: Buy a new valve at an appliance parts outlet. Make sure it's the right one. Many times they will come with instructions. Unplug the unit. Shut off the water and remove the hoses. Remove the back panel to access the valve. Remove the old broke valve and replace it with the new one. Replace the panel. Attach the hoses and turn on the water. Check for leaks. Plug in the unit and give it a test. Try all the temperature settings. Congratulations. You are now a professional..

Q: I have mitral valve prolapse and I don't get why only some people get chest pains? and what causes people to get chest pains with M.V.P (mitral valve prolapse), like me. PLEASE HELP!!!!!!!: With MVP, your mitral valve is smaller due to extra tissue. This makes it a little bit harder for blood pumping through the valve to get through, which can often times cause an aching pain. As far as I've seen, this is not life-threatening and the pain can be treated with over-the-counter painkillers. Imagine you kink your garden hose while it is running. The water can't get through the hose and the pressure builds up. When you unkink the hose, the water flows freely. Your mitral valve has a permanent partial kink or blockage. The blood behind that partial kink can get blocked up and cause pressure in your chest. Be sure to get regular check-ups with your doctor, just to be sure your MVP is stable. Your doctor will also be able to suggest some pain remedies.

Q: Just wanted to know what the significance of the number of valves is?I know that theres valves for intake and exhaust if i'm correct.if there is four i'm guessing its 1 for air and 1 for fuel if its fuel injected. and 2 for exhaust?are there bikes with 3 valves or more than 4 valves and why?and a basic carburated 2 stroke just has an intake from the carb side and then an exhaust.please give me more info and let me know if i'm correct or not.: This Site Might Help You. RE: 4 Valves per cylinder? Just wanted to know what the significance of the number of valves is? I know that theres valves for intake and exhaust if i'm correct. if there is four i'm guessing its 1 for air and 1 for fuel if its fuel injected. and 2 for exhaust? are there bikes with 3 valves or more than 4...

Q: When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!: The flow coefficient is a measurement usually given for a valve fully open, identified in the specs as the Cv. It basically tells you how much flow you'll get through the valve for a given pressure differential across it, or conversely how much your pressure will drop if you force a certain volume through it. Some valve types are effectively orifices (gate valves) or short lengths of pipe (non-full-port ball valves), others like solenoid types have more complicated internal paths the reduce flow because of the fluid having to change directions in addition to squeezing through orifices.

Q: This valve has flow indication embossed on their body.: the gate valve is a very important one in flow measurement and also used to help the measure of flow. for example if you know the pneumatic comparator operation, you can easily under stand the gate valve. the gate valve is mainly used for to adjust the float in the tube to zero position or the clearance value.

Q: hello I am having trouble inflating my back wheel tube. so i guess i will just tell you what happened. well i came back from the bike shop with a presta valve adapter and i put it on my tube. it fills up too near full psi but just after a ride around the block it is flat. i have no idea why. please help me! also its a mavic tube 700 x 23, vittoria rubino pro 700 x 23 tire, and a vuelta xrp 17 deep v back wheel. thanks!: You have a slow leak. You need to pull the tube and patch the hole or replace the tube.

Q: When I put my check valve on my air line the air doesn't come through the air stone but when I take off the check valve it works. Also I switched the sides of the check valve and it didn't work. Click the link this is the air pump.: Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
