1999 ram 1500 4X4..85,000 miles...truck suddenly started erratic idle, surging, hesitating when stepping on pedal...I then hears a rattling sound like a rock in a tin can kinda sound underneath the truck from around the oil and transmission pans, t case, catalytic converter area... I can't zero in exactly where the sound comes from...there is no check engine light...any information would be appreciated...thanks..

 

Hit the catalytic converter if it rattles it's bad

 

The muffler bearings are bad!

Or, just a bad cat. Gut or cut off.

 

I was wondering about cutting off cats... will that affect how it idles or accelerates??? With 02 sensors and computer controlled air and idle settings and all that? Assuming that the problem is the cat...

 

Sure, it idles and accelerates better! Gut that thing or get what I have: the Jegs Y-pipe. Truck has more getup than I've ever felt and it's at over 271k.

 

Thanks for all the responses... how do ya "gut" the cat???

 

Pull it out and talk all the internals out

 

But, they have to really want to come out.......

The Fanatic posts from a phone, so, sometimes it is necessary to decode his posts. What he really means is, TAKE them out. (referring to the catalytic converter on the truck. Not your girlfriends cat...... that'd be bad.)

 

Sorry my mistake, but sometimes you have to talk it out also!

 

You know I get a great deal of pleasure from your posts.
