Loud noise

I have a 2001 Ford Ranger Edge V6 3.0 with 103000 miles. I have two noises coming from the engine. One occurs when I accelerate and when the speed remains constant the noise will subside and occur when I need to speed back up. Ford said it had to do with the EGR so I replaced the valve and still no luck. I am thinking that I may be the vaccum lines because after the truck is warmed up and they are taken off the valve the engine should show that something is not right. The other noise is coming from one of the pulleys b/c the belt was changed and the pulley next to the alternator was also changed. This pulley is located where the belt goes under it and has a smooth surface. Mabey they need to be aligned or it is the tensioner. Please any help would be greately appreciated. I have spent a lot of money trying to fix these problems. Your website is a lot of help. THANKS!

2001 Ford Ranger Edge V6 3.0 104,000. The noise that is coming from one of the pulleys is a chirping sound that gets faster as I speed up and is louder when the truck is fully warmed up. The other noise that occurs when I press the gas pedal is really hard to explain. Its loud and makes a constant piercing noise when the gas pedal is pressed. When I put the new EGR valve on I did not clean the area, I just bolted the new one back on. Was that okay? I thought that mabey something was wrong with the valve because after you take off the vaccum lines the car shows no sign of hesitation or stalling once warmed up. Does that mean that the valve is bad or is one of the vaccum lines is bad? Hope this helps even though I know it was hard to really describe the noise. I have brought this to many mechanics and they have tried to figure out where the noise was coming from but it has remained a mystery. Thanks.

I have the same motor, but the 98 version. I have replaced the belt, tensioner and Idler pulley several times. With both dealer and after market parts. When it acts up, I'll check the pullies for play and the tensioner for misalignment. Other wise I live with it. Some seem to have that inherent squeaking noise.

As far as the acceleration noise, I need a better description. Having said that there was a problem with a pinging noise on cold acceleration. Mine does this. Ford's remedy was to replace the Computer and the mass air flow sensor with revised parts. I have been told that it doesn't always work by a few Ford guys. I also live with this noise! :Wink:

2001 Ford Ranger Edge V6 3.0. The noise when I accelerate is hard to explain without actually hearing it in person. It was like eeeeeeeeeeeeeeeee. The only thing I can say is that once the speed is up say to 30mph for instance and if I want to speed up the noise will happen. It sounds like it is coming from the driver's side near the front. Is there any way to see what it could be because without hearing it is hard to explain? Let me know so I can help you figure out what it is. Thanks.

Brake warning sensor on the rotor? It may sound far fetched, but I have heard the noise from the sensors at weird times that I wouldn't have expected.
