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: I have checked this and ensured that the flow control is turned on. I have also found that:1. Valve works in manual mode2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.I am not sure what could be broken as manual operation works and solenoid sems to be working. Any ideas?Thanks.: Toro Irrigation Valves

Q: So I tried to go skydiving last weekend and they told me know because I have mitral valve prolapse. I've had it for years and it's never really been a problem for me, I just have chest pains sometimes and feel palpitations. What would be the danger of not telling the skydiving place about my problem the next time I go in? I know I should tell them, but I want to skydive. What could happen to me if I jump? No lectures about what's right and wrong here please. I just want to know what's the worse that could happen?: There are many people with mitral valve prolapse that never have symptoms related to it and never have any problems as a result. Mitral valve prolapse can lead to the backflow of blood through the mitral valve known as mitral regurgitation. This can potentially lead to abnormal heart rhythms, such as atrial fibrillation. The concern with skydiving is that it would lead to a surge of adrenaline resulting in increased heart rate, strength of heart contractions and overall workload of the heart. If you have MVP without regurgitation, then your risk would be similar to the general population. If you have regurgitation it depends on the severity the regurgitation. If you have mild regurgitation, then it also should not be a problem. If you have severe regurgitation, then you could run into problems from the increased workload of the heart. In this case, I would suggest you discuss it with your Cardiologist. It is unlikely that you have atrial fibrillation. If you by chance do, then it depends on how well your heart rate is controlled. If there is any doubt, then ask your Cardiologist. Good luck.

Q: Is it posible there is underground valves? I looked all over my yard and can only find2 valves.???: Yes, electric valves are set on the Mainline which is under pressure. Usually in a loop around the home with the valves set where the zone starts. Some are designed to have a short mainline with the valves set in a large box next to a vacuum breaker. All valves need wires that run from the clock. Sorbet can be found with a metal detector if you simply can't find them. You can also set them to go off manually time delayed a few minutes, enough to go listen to hear the valve opening.

Q: I acquired an old valve guitar amp not long ago and i think it needs new valves trouble is the valves that are in it have no writing left on them and there is one valve completely missing how can i find out what type of valves to put in it. Could i use a multi meter to see what voltage etc is going into the valve socket and then find a valve with matching voltage. Thanks for your help Marc: Go okorder and search for the schematic diagram for your amp(enter the brand and model of your amp)!

Q: had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning: A gate valve is used as a shut-off, not a regulator. It is supposed to be either all on or all off, and the handle only has a total movement of 90 degrees. When the handle is aligned with the pipe, it's on, and when the handle is perpendicular to the pipe it's off. If the handle is turning more than that, it's broke and needs to be fixed or replaced.

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: does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?: Yes they do go bad! It sounds like that is your problem. You can try bleeding the proportioning valve with a brake bleeding gun, making sure to open every valve then re-bleed the brake system this will eliminate the possibility of a air bubble in the proportioning valve. I have changed probably ten or twelve of these things in my ventures.

Q: I went look at a car, and the guy selling the car said that the engine valve is leaking. Is this a big deal? How urgent would it need to be fixed? How much would that cost?: He most likely told you the valve cover is leaking. The words engine valve leaking don't make any sense or point to anything else. The valve cover covers the valves which have oil splashing around Sometimes the gasket that keeps the cover from leaking dries out and breaks. Then oil seeps out onto the engine. It's not an urgent fix. But then it's quick and cheap to fix, so most people fix it.

Q: I have pressure steady at 13psi --- water temp is normal range but the external emergency run valve has been dripping since i turned the boiler on this year? Expansion take was empty, so I forced water through and then drained it and reopened the valve.....I am stuck and getting concerned. Anyone have a suggestion?Would really apprecite it?Additional info:Boiler is a Gas Powered unit by MASTER from the 80's.....: The TP valve will naturally wear out over time, if it has never popped open the washer inside of it has hardened, when you opened it it didn't seat properly when it closed back up, causing the drip. This is not an unusual or dangerous condition, the TP valve will usually wear out before the boiler does, it can be quickly and easily replaced. The valve will still function with a leak, but this reduces the efficiency of the boiler. DO NOT, under any conditions, DO NOT plug the leak by plugging the opening on the valve, this creates the potential for a very dangerous condition, let it drip until it can be replaced.
