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.: This Site Might Help You.

Q: I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?: === take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have

Q: i have a 1997 dodge avenger ES with a 2.5L v6. im wondering if my EGR Valve could be bad i get about 14mpg on gas. my car has a poor idle but will not stall idle gets kinda bad if the airconditing is on. I did a complete tune up and yes it was done right. and i changed my Idle air control valve. after i changed the valve i drove a few miles and i got a check engine light for insuffecient EGR flow but then it went away and never came back. I took the valve off and cleaned it with carb cleaner. im trying to find out why my ide is kinda poor and if the car sits a few days it takes a little longer to start.my motor has 142k miles but has been properly maintained.: you should be getting way more than that on gas mileage at least on the road anyway,a bad egr valve will cost you around 3-5 miles per gallon if its leaking and doesn't seal of when it should, i went through this with out stratus ands its 2.4.it got real bad mileage,cleaning the valve didn't help it none at all, i went to a salvage yard and got a used one off a blown engine to try it to see if that would help it and the mileage came back up on it so i replaced it with a new one,you should average about 15-17 in town with that one and around 21 or better on the highway if its running right,id try that if everything else is right and you have double checked for codes and don't get any but the egr valve you don't have anything too loose,if you have had it scanned and dont come up with any other codes it would about have to be that or really low compression on the engine causing that too happen,a weak fuel pump believe it or not will cause one to get really bad mileage and run and idle bad also,and this is often over looked as a possibility,check those things if its not them we,ll figure out whats causing it,good luck.

Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?: Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.

Q: i dont get how valves produce the sound? and why did we change to solid state? was that because they we're used in stereos?: Most valve amps I have used reproduce the sound of a tube amp. Tubes have a warm sound and can be overdriven to get that good rock crunch distortion sound. We went to solid state because they were durable and didn't require the maintenance of a tube amp. Printed circuits and transistors cut the cost of manufacturing. The old tube amps still have the purpose and they never quite matched the exact sound of tubes with the solid state amps. That is why they are making a lot of tube amps now.

Q: why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?: Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.

Q: what to use to inflate self sealing tube with the presta valve?: Gazoo If you do not have a pump that will accept a presta valve, then you can either buy a presta schrader pump, or a presta valve adapter. I have an adapter in each of my seat bags, they are only a buck or so, and will allow you to use service station air on your trips. Just cause you may not know, the presta valve has a rotating screw inside the valve. So to add or release air you must take your fingers and twist on that knurled circular end so that the presta valve extends away from the valve stem. Then when the tube is filled, twist it back tight to seal it off. Soccerref

Q: Recently, my best friend told me that he has tricuspid valve disease. So basically, the tricuspid valve in his heart is leaky and doesn't close tightly, allowing the blood to flow backwards.I just have a few questions about it and i don't wanna ask him because he doesn't like talking about his condition and i don't wanna make him uncomfortable. I just wanna know, is there any risk on his life or will he be able to live his life normally?Also, he doesn't take good care of himself at all. He completely ignores his condition. So i need to know, what should he avoid doing? Maybe I can prevent him from doing all the things that could hurt him. Most of all, i wanna know if there is anything I can do to help him.Guys if there's anything you can tell me, then please do. He's like my brother, we've been best friends since 1st grade and now we're both 16. I just want him to be okay.: Any sort of valve surgical technique includes exposing the aorta of the midsection, hence it rather is one among those open heart surgical technique. over the years, this has replace right into a incredibly simple technique for heart medical doctors and it has a fulfillment fee of in simple terms approximately 80-ninety 5%. there is an threat which you may choose yet another surgical technique afterwards, yet that purely happens in approximately 5-10% of sufferers that get the surgical technique. The survival fee for this operation is extremely extreme and purely 5-10% of sufferers adventure any undesirable outcomes throughout the surgical technique. This consists of an infection, stroke, allergic reaction, or bleeding. i'm going to keep you in my prayers Alex. maximum suitable of success to you!

Q: So my engine was back firing and me and my dad adjusted all my valves both sides. Runs better, But it still back fires. What could be the problem? Its a Chevy 350 with a brand new mild cam. 600cc carburetor. And new shorty exhaust headers. However I don't have exhaust pipes on my headers just yet because I gotta get pipes to mesh properly with my exhaust. Could it be air coming back up from the pipes causing it to back fire a bit? Like I said we just adjusted all the valves.: Cam timing off, ignition arcing, ignition timing, intake leak. You don't indicate if it is backfiring out the exhaust, intake or both

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.
