Question about 2002 Chevrolet Impala

2 Answers

I just had a new catalytic converter, and spark plugs/wires put on my 2002 impala v6 3.4L. I drove it about 10 miles just fine, and now when I try to accelerate the engine loses power, starts shuddering and the engine light blinks. Any ideas as to the problem?

The blinking engine light is a definite sign that vehicle is misfiring.I would check and make sure none of the wires came loose.You can also check the plugs to make sure none were cracked during installation.If you have access to a scan tool it should tell you exactly what cylinder or cylinders are misfiring.

You still have a bad misfire problem, get it fixed ASAP before you damage the new converter.

The flashing light means the problem is serious enough to cause damage to the catalytic converter. Have the computer scanned for trouble codes to proceed. And get the plugs replaced.

You could be right about the catalytic converter but I would check your air cleaner first and if it's plugged or dirty replace it you may also have a vaccuum leak

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.

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!

I just had the same problem. Check the catalytic converter. It took me forever to get over 30 or 40. Drove everyone in the road nuts. They initially thought it was the transmission. Not so, clogged catalytic converter. I got it tuned up and the engine runs fine. Wish I could sasy that about everything else on this lemon!
