Hi, picked up a nice 2001 Regal LS as a summer car until i can fix the AC in my GP. Trouble is, this car has NO POWER, especially compared to my GP. Now they are the same engine and trans (my GP is not super charged), why the discrepancy in power? I replaced the fuel filter, air filter, checked plugs and wires etc. Car just had the upper intake replaced a week before i bought it, but it all seems in order, no loose vacuum lines or anything like that. I have no SES light on or stored codes. I'm wondering if my CAT isn't clogged as i heard there was some sort of issue with the 01-02 regals. Is there a good way to test this?
I should mention what i mean by no power though. I'm not trying to race the car by any means, just normal driving. When you go to pull out of a drive way for example, the car goes slowly out, even with more gas pedal, then it kinda seems to stall off or flatten out and then go a little more. Its hard to explain, but when i step on it in my GP, it will pin you back in the seat, it seems like the engine is spinning, but not turning the wheels or something. Trans is not slipping, and it shifts really well for having 140k miles on it. What would it feel like if the cat were bad/clogged? like what i've described? I have more than 120k miles on the car so i'm sure i can't get this fixed for free by the dealer. Let me know, thanks!
