#13134 of 13621 Hesitation during acceleration
Feb 15, 2006 (6:11 pm)
I am new to this forum and have read several messages regarding hesitation, but have not seen one that duplicates my problem. I have a 2000 Chevy Impala LS with the 3.8 liter engine which hesitates and jerks when accelerating between 40-60 mph. I took it to the dealer and he changed the "throttle position sensor" and the problem is still there. They want to change the torque converter clutch for roughly $800.00. The car has 68000 miles on it and I am hesitant to put that much money in it, as I have had very poor luck with the American cars I have owned that have over 60,000 miles on them. My question is-does this solution seem reasonable, or does anyone have any other ideas about this problem? Thank you for your help.

Seems like some folks have had problems associated with clogged catalytic conveters that involved stalling; you might check that angle (which would also be covered under warranty, most likely).

The auto dim rearview mirror on my 2000 Impala LS has stopped working. I have checked the fuses and have not found any blown/bad ones. I have even reseated a few in case they had a bad contact. Does anyone have a wiring diagram or an indication of what I should find on the wires going to the mirror so I can track it down with a meter? I looks like there are 5 wires going to it. The mirror does not have onstar on it and only has buttons for turning on the auto-dim mirror and the 2 map lights.

Did your mirror stop all at once, or did it sort of fade away over time? I just replaced mine two days ago (2000 Impala); it had gradually quit working - was fine for a couple of years, then it quit working towards the top & bottom (with a band in the middle that worked), which eventually diminished to nothing.
Do your map lights still work? If they do and the autodimmer doesn't, then I'd say the problem may be your mirror. It's easy enough to replace, but kind of expensive (I paid $160 at the dealership here, but installed it myself).
If you're not getting power to the map lights either, then your problem is probably more along the lines of a short or blown fuse.

The mirror just stopped one day - all of a sudden nothing. The map lights still work so it appears to be getting some power, but I figureed with 5 wires, one may be a bad signal from the BCM or something like that.

Well, I've been searching on the internet and I think I found the wires and their functions.
Dark Blue/White = Retained Accessory Power +12
Black = Ground
Grey = Switched Interior Lights to BCM
Brown = +12V Ignition
Light Green = Reverse Lights
If I had to take a guess, I would think it would be due to the +12V Ignition or the reverse light wires since the map lights are working.

I recently bought a 2001 Impala. The tire monitor light on the dash came on the other day because one of my tires had lost pressure. No problem, right? Well, now I can't reset it. I've tried the following: With the key in the "acc" position, hold the disp button on the radio until "settings" is displayed. Then, using the seek buttons, select tire monitor and reset it. The only problem is that Tire Mon is not one of the options in my menu. Is it possible that the dealer could have at one point disabled this with his scanner? I've also had suggestions to try turning the headlights to parking-lights, off, parking lights, off, parking lights within 5 seconds and to simply press a reset switch in the interior fuse panel - but neither of those worked. I can't even find a switch inside my fuse panel...I assume this is because the car is equipped with the RDS. Someone please help - the light is driving me nuts!!
I've had the same problem. Disconnect the positive battery cable and reconnect. You will lose your radio station presets, etc., but it will reset the tire pressure light.

Does anyone know the type of light bulbs that are in the interior of a 2004 impala?

Well for starters you can read the owners manual and every bulb thats used in the vehicle is listed. Which bulbs are you trying to find out about? If you dont have a manual, I do, and I can look up the bulb type and number for you.
#13143 of 13621 Speedometer Problems

Has anyone experienced speedometer problems with an 05 Impala LS. The first sign of trouble showed up the first time I drove the car for over an hour. I was on the freeway, going with the flow when I looked down to see that according to the speedo I was going 120 MPH. It then continued to do a 360 and come alll the way around and back to 40 mph. The dealer said they were having a lot of problems with the speedos and that I needed a new one. They said they ordered it and for me to come in to get it replaced. Then they said the speedo was ent out to be repaired. When I got the car back I thought it was ok. Then it got dark and I could see all the warning lights collecting ambient light from the speedo, blinkers etc. They said the place that repaired it didn't put a filter back in. Then I was driving down the road and saw a police cruiser ahead and naturaly looked down to check my speed, which said 48 mph. I was in a 45 MPH zone so I was not concerned until I saw the lights come on and I got a ticket for 60 MPH. I later had my wife get in her car and via cell phones I verified that when my speedo said 48 mph, hers said 60 mph. Testing from 5 mph up to sixty mph showed that the faster I went, the firhter it was off. I took it into the dealer who said they did a GPS test on it and it was only 4 mph off and thats not enough for the warranty to fix it. I said I checked the car myself against 2 other cars and got the same discrepency of the speedo reading 48 mph when two other cars said sixty. They then said they would do the same test, however they did not let me accompany them in my car while they "tested it" Anyone have any ideas??? Thanks
