2002 Impala sounds very rough. One day it worked fine as usual, drove home and parked overnight. came out the next day, car sounds terrible. I put into reverse, and it sounds even worse when in gear. car seems to shake, especially when attempting to back up or pull forward (couple of feet only) I am unable to drive my favorite car. Please help with ideas!

Update from Jan 24, 2017: mileage on the car is 226,000

Impala LS 3.8L 3800 Series Ii

  • Automatic transmission
  • 170,000 miles

OK... we have a 2002 Chevrolet Impala LS with the 3.8L 3800 Series II engine. About six months ago the catalytic converter went to hell and now is no longer existent (A straight pipe is now where it was). About two months ago, we noticed that once in a great while the car would chug when accelerating from a slow speed, like after you make a turn, or seemed to "miss" for a few seconds when at cruising speed. This has progressively gotten worse to the point of the engine quitting while going down the road or idling at times and to allowing no acceleration after slowing to turn. We replaced first the inline fuel filter. Not the problem. Then we replaced the fuel pump. Again, not the problem. (Thank God we don't have to take it in and pay labor!) Now, we hooked it up to one of those little handheld portable code diagnostic computers and it came back with "MAF/VAF" (in this case it's MAF), "O2 sensor bank one low input" and "catalytic efficiency" (which I'm guessing is because there is no catalytic converter. Anyhow, these are not exactly cheap sensors and I was wondering what thoughts might be on most likely culprit. I also was thinking that it could be a throttle positioning sensor? That's just my thought. Another symptom that I am not sure is related (doubtful) is that sometimes (maybe 1 in 25 starts) you have to hold the key in the start position for a couple seconds (once it was almost 7 seconds) before it even engaged the starter to turn over. As I said, I think this is separate and I know we are supposed to list two problems in two places, but if it's possible that an ignition could be causing all of this I wanted to mention it here too.

Car would stall while driving,and would not start right away,had to keep cranking it and eventually it would start,brought to chevy dealer and control module, battery, ignition coil,and crank sensor were all replaced nothing worked. Last week it got to the point that it would not turn over when trying to start, and yesterday it went completely dead, will not jump and when jumpers are connected there is no power. Was told by chevy dealer I should trade the car in. Car only has 26000 miles on it and was always garaged looks like its in excellent shape, I would like to be able to get it fixed.

(reported on)

Impala LE

  • 60,000 miles

Figured I bought a reliable vehicle. In the month I have had it, I already replaced the intake manifold gasket (common problem at 60,000miles for the 3.1 and 3.4 litre gm engine) and now find the windshield rubber has defects... and now I have to drop the tank and replace the fuel pump.

I feel that I also having steering and suspension problems on the rise.

This full size car isn't built full strength.
