Question about 2002 Chevrolet Impala
I have a 2002 with the 3.8l v6 and while moving, when I step on the gas to go, it's like the car bogs down very badly and doesnt want to go. I've changed the fuel filter and the throttle position sensor.
Have someone do a back pressure test on you catalytic converter. I had the same problem and it turned out that my converter was almost completely plugged. I was also getting a check engine light indicating a misfire on cylinder 4. Once the converter was replaced, the problems went away.

Same here. Cylinders 1 and 6 were misfiring; after I had replaced my spark plugs, air filter and fuel filter my mechanic determined that the cat converter was completely plugged. I got it replaced and it runs good as new.

SOURCE: 3.8L Major Hesitation
the 2001-2002 3.8L V6 Naturaly Asperated (RPO L36 - Vin K) engines experience a problem when the front endcone insulation from the catalytic converter breaks away and blocks the front of the first catalyst brick preventing free flow of exhaust gas through the converter. GM has issued a special policy adjustment extending the warrenty of the catalytic converter for 10 yrs or 120,000 miles regardless of ownership. a dealer will replace it at no cost! take it in. i just did and my car runs like new!
