snails:
I actually did the Aircare back during last summer and thought all hope was gone and did nothing about it. I can't find my Aircare results but it had something to do with "Throttle Position" and "CAT converter....."
I went to one mechanic and he said that my CAT was fried and that I'd need to replace it, quoting me about $1200

I really can't afford that
Really sorry if that information doesn't help :P

Sorry, but..
What is my egr system?
Where can I get new plugs/wires? How much would they cost?
And is o2 = oxygen? If so, where would I be able to check it?
