Losing power and dont know why!!!!! Ok, here's my problem.... My car was losing big time power especially when going up hills. When I stomp the accelerator, my RPM's shout up but it feels as though my car is stuck in gear. I just had both cats along with all 4 O2 sensors replaced. Any feedback would be greatly appreciated!!

Yes sir, I actually had it replaced about 3 months ago. A friend of mine told me that it sounds as though my computer hasn't reset after the new cats, O2 sensors. Could there be so truth to that?

Same problem here. My camaro usually runs 10.50's on motor and is running 11.50's now. What could cause this? Changing fuel filter today. Put new valve springs in last fall and new plugs a few days ago. Any ideas?
why did you replace cats? were they clogged? car should relearn after few cycles..2 to 3 rides..when was the last time you changed spark plugs and wires? air filter? engine codes?

Well, I replaced my cats because of the rattling I heard one day when I started my car then the change in power lose. I had my Magnaflow cats put on yesterday, both sides, and my mechanic told me they were very clogged up and that my O2 needed to be replaced ASAP, so they got replaced. Now, to find out that the rattling that I heard wasnt my cat, it was my rear passenger coil springs vibrating causing the rattling noise. I had the plugs and wires changed about 4 months ago. Now air filter, hmmmm, that could be a possibility, and the only engine code was for my O2 sensor which I knew about......
