Q: whaT ARE THE SYMPTON OF A BAD EGR Valve Position Sensor loss of power ?1998 toyota camry v6: Typically when those sensors start to go bad, the EGR valve doesn't modulate properly between open and closed. When that happens you usually notice a sort of fluttering in the power delivery, often when cruising at a set speed but sometimes also when accelerating as a result of the wrong amount of exhaust gas being recycled back into the engine. You sometimes will notice a loss of power when accelerating as well. If the EGR valve is opening more than necessary it will be allowing more exhaust gas back into the engine than is beneficial....and that will reduce the amount of power the engine produces. If the EGR valve is staying closed more than necessary, you might not notice as many driveability issues but you'll probably notice your average fuel mileage decreasing a little and/or a check-engine light being triggered and/or a failure of an emissions test (even if the check engine light hasn't tripped) if you live somewhere that emissions checks are required.

This is a very unusual thing.

Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =): PING ! You probably have a minute dent in the valve casing that the eye cannot see.. A repairman will buff it out . Meanwhile it is abrading the valve ( like a car cylinder ) so make haste to the repair shop.

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: My doctor detectd a heart mumer. I am 48 years old. Had a echocardiogram performed. He says that I have a sightly irregular valve and I do not need to take precautions. I run three miles a day. I have heard that this condition makes your heart more suceptiable to infection. You should take antibiotics when dental work is done. My GP is a man of few words. Just says continue as usual and nothing needs to be done unless there is further symptomns. My question: Should I follow up with a heart specialist or would it be over doing it? Should I go on antibiotics when I get dental work? Can this Slightely irregular valve get worse?: I genuinely have a coronary heart murmer which i grew to become into clinically determined with while i grew to become into born and it hasn't made any issues for me. The scientific institution can provide her an echocardiogram which will enable them to verify the quantity of the middle murmer whether it particularly is maximum possibly to be an harmless murmer which will require no therapy and because having mine clinically determined at delivery i've got no longer mandatory to have mine checked till i've got been given pregnant and had to have a repeat echocardiogram because of the fact they lost my previous outcomes!!

Q: I bought a Bb trumpet from Ebay (I know, probably not the best idea) and when it arrived it was really good, except the valves. They wouldn't go down (or up) really well, so I oiled them, and it helped, but it still won't go up properly (it might go up halfway, then suddenly stop, then go up slowly). The valves sound like they're scraping the side a little, and valve oil doesn't do much good. I don't know what brand it is, so don't ask. Another thing, is there such a thing as over-oiling?: Sell it on Ebay. Now go to a music shop and play one before you buy it. Lesson learned. I bought a pocket trumpet that way. Same problem - took it to a shop, never go the valves to work right. Eventually pitched it. I'll never do that again.

Q: Its a 1981 Monte Carlo SS with a GM 350 crate motor. There is oil all over the heads valve covers. It isn't my car, but I was thinking of buying it..Thank you.: It needs a new valve cover gasket which is cheap and easy to replace. Gaskets dry up and break from heat and age. Then all that sloshing oil underneath gets out. Loose valve cover bolts can also be a problem. And the valve cover may have been damaged by someone over-tightening the bolts. This thing is a 100 in human years. What happened to the valve cover gasket (rot from heat and age) is just one example of what has probably happened to many things on it - other gaskets, seals, hoses, tires and belts. Have seller prove he did a timing belt change when needed. It needed that at about 100k or 11 years ago. If seller can prove it, then guess what? It now needs another timing belt.

Q: I am looking for a full valve guitar amp for around ?300.It needs to be loud enough to play with a quietish drum kit.Currently i have looked at an epiphone valve senior in both and combo and cab and head form. i have also looked at some smaller amps such as the vox ac4 but am a bit worried about its small size. any advice would be greatly welcome. many thanks in advance.: Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.

Q: i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!: dude leave the power valves alone. you do not know what you are doing.
