When i accelerate it sounds like a hole in my muffler, but when I maintain a constant speed it goes away, what can it be?

When I am idle it sounds like a hole in the muffler but not really loud, but I accelerate it gets a little bit louder, but once I maintain any constant speed it goes away. Any ideas on what it might be?

It could be a small hole or the baffles are loose in the muffler itself.You can either check this out yourself by jacking the vehicle up and starting it and see where the noise is coming from or have it looked at at a repair shop.Make sure they show you the problem if they find one.Don`t just take they`er word.Hope this helps.Good luck.

Why is there muffler noise?


Could be a loose element in the muffler that vibrates at certain engine RPM. Or a small hole in the muffler. Sometimes the problem is as simple as a loose clamp, either a clamp that holds the muffler to the chassis or a clamp that joins two exhaust pipes. A loose clamp can allow the muffler or pipe to vibrate against the frame. Clamps are cheap - a lot cheaper than a new muffler or exhaust system.

Car will not accelerate after 30 mph


I would look at a possible blockage in the exhaust, including the catalytic converter.
Next would be fuel pressure.

1998 Durango will not idle


Check A.I.S./I.A.C. motor on throttle body. Known by both names, Automatic idle speed motor (AIS) Idle Air control (IAC) . Usually mounted on side of throttle body, with 2 or 3 torx screws and it's job is to adjust idle at all times as necessary, such as when AC on, turning, etc when extra load on engine, it will increase idle as needed to overcome the load and maintain proper idle speed. You can often remove the motor and clean pintle (pointed end that goes inside throttle body) with throttle body spray cleaner as well as spray inside the port (hole) that it comes out of. Sometimes this will cure the problem for quite a while, but if only for a short time, and it happens again, replace it.

1997 Oldsmobile Achieva - check engine light is on and car is running sluggishly...brand new motor installed 6 weeks ago.


What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.

2001 Dodge Ram 1500 5.2L Slow to get up to speed


The problem sounds like a plugged exhaust system (muffler or crushed exhaust pipe), or a restricted intake system (air cleaner or something blocking the intake passages. It's strange that nothing is showing on a computer scan. If nothing can be found, take a chance by replacing the muffler. Good luck!
