my 99 ram 5.2 is making muffled sound at idiol or on the gas. There is no power at all please help

 

Sounds like your cat is clogged. Have someone run the engine and rev it a little while you put your hand by the exhaust outlet. If there is little out pressure and you hear a hissing sound - the cat is bad. Go get a Magnaflow if you can or just a new cat. You can also find someone with a temperature gun to take readings of the exhaust before the cat and after the cat. If the temp is higher before the cat it is bad....

Also - there is a "sticky" thread at the top of the page on this subject.....go to it and read up on the subject. Forum search for " cats " there is a ton of stuff on the subject

 

ty I will check it

 

If you have heard a rattling sound coming from under the truck recently that is another sign of a bad cat.

 

Sounds like a dying cat to me


Legal way to fix- Buy a highflow cat or another cat...


Illegal (easier) way - get an O2 sim and take the cat off, and gut it... then hang it back up

Just my 2 cents =)
