I'm thinking that my cat is clogged up because my RS is not running like it used to.

What are the symptoms of a clogged up cat? Would this cause my car to idle rough? And it doesn't seem to pull near as good as it used to. What else could be causing this???

I really need to start spending some $$$ on my car because I keep bitching about not having enough power. I have decided to just do something about it.

By the way, I have a 92 305 tbi 120 k w/open element and no muffler so I know it should be faster than ever now.

 

If you have the bucks get a complete SLP exhaust system, headers, and cat back system, and for the love of god put a muffler on it, anything without a muffler sounds like crap, you might think it sounds good because it's loud, but it don't!!!

Maybe its ignition problems. I had a rouh Idle and a tune up fixed that.
