2005 Ford Escape V6 Rattles under acceleration

[kirmit77]

Cat. Converters have a honey comb type material inside of them. Sometimes they can break down and rattle in the system. Also parts in the mufflers can rattle too. Whatever you do, do not get under that car while your wife has it in gear and trying to mash both brake and gas pedals..... You might laugh but it has happened. Not being able to have it in front of me like Okie said, it is hard to diag. the problem.

Good luck to yah... and watch out for the exhuast... it gets HOT

If the engine light isn't on it's probably not a sensor Don.

I agree with kermit, it's probably something in the exhaust. Awfully hard to diagnose noises on a key board though.

Can you replicate it sitting in the driveway? With the brake on put it in gear and ease into the throttle until you hit that sweet spot that produces the noise.

Get some help and trace it by ear.

The check engine light is not on.

I tried pushing and prodding every heat sheild I could find and the only thing that moved at all was that flex hose piece on the exhaust.

most likely somewhere along the exhaust system.....

but if you could drive it here to houston I would do a FREE check on the car

Ha ha.... your probably right kermit it's probably one of those MANY usless heat shields popped a spot weld.

Check engine light on?

Bad knock sensor?

It sounds like spark knock, the newer model cars have what is called a knock sensor, that signals the computer to retard the timing when it senses spark knock, and prevent damage to the engine. check and see if it is working.

I've heard a similar rattle before, it was some rocks between the heat shield and the catalytic converter.

My sister has a 2005 Ford Escape. Has about 95,000 miles on it. She told me it was making "a noise" under accelleration. She could only hear it with the windows down and next to a wall or something similar.

I went for a test ride with her and we could only hear it when accelerating at a slow speed and near a wall or something like that from in the cabin. I could also hear it walking next to the car when she moved it on my driveway. It sounds very much liek a loose piece of sheet metal running against something but at a higher rate than anything is moving.

I put it on ramp stands and climbed underneath, I could not see anythign that could be rubbing against any of the drive train. I pulled the drivers side wheel and pushed/ slightly bent the dust shield on the brake disc back a little bit. No change. I did notice that the flexible sleeve on the exhaust has pulled loose form its end. I am concerned the noise sounded like it might be internal to the drivetrain.

Appreciate any thoughts.
