My car just developed a rattle at idle which increases in frequency as the rpm's increase.

It sounds virtually identical to what occured on my Quad-4 Malibu which turned out to be the timing chain tensioner.

Is this a common problem on Catera's and does anyone have any suggestions as to what it could be?

Cateras don't have a chain for timing, they do have timing belt thus they don't do mechanical noise.

Does the check engine light on?

My 97 catera had some really bad sounds at startup one day. I turned it off and called the tow truck - took it to Cad dealer and they said the tensioner was bad but that it was a recall item - they replaced it free along with a belt and a few other things. Who knows, maybe check for any recalls on yours.

the tensioners are a good place to start. had 97 catara tensioner was knocking. bought car cheap previous owner thought it was a rod. start with that tensioner bracket and powersteering pump pully must be removed in order to remove inspection cover off front of motor for more info.
