Pulleys... Rough Idle...

[MatthewDavid]

Hey guys me again!... anyways my girl got our lincoln mark '97 LSC stuck in the snow yesterday... it took a lot to rock it out... but I never took it over 4 grand cept once it went way up fast on accident... but I was wondering it's running alright when it's over a thousand RPM's... but any lower and it's running rough... I was wondering if a pulley could have something to do with it... I popped the hood and it sounds like there's A. a squeak from one... and B. when you rev it up there's a little bittle of a rattle... but it sounds like it's commin from a pulley... when the belt tightens... I could be wrong though... any help would be awesome thanks!!

Did you replace your belt tensioner yet, and Idler pulleys ?

Not yet haven't had the money yet... I'm thinkin maybe just changin them all out can't be that bad and it's probably better to be safe than sorry... just wondering if that would cause the car to idle rough?

Both my idler and tension pulleys went bad in like a month from each other. They where pretty cheap from Autozone so I would just do em both at the same time.

However my car is idling ruff again and I do believe it's from the colder weather now. My IMRC are throwing a code now along with the ruff idle so I may have to look for a vacuum leak somewhere
