2000 Chevy Impala
Engine size = 3.8
Repairs for this problem = cold air intake
GM tech = kk
question = when i get on the gas from a stand still why does my car will
sputter a little bit then take off. Also when rpms are at a steady pace the
rpm gauge will go up and down till i give it more gas. What could the
problem be? Thank you.
KK:
Not much experience with these cold air systems, but does not sound
related. This does sound like a bad plug wire, coil, or spark plug. Spark
plug wires tend to "break down" under heavy electrical load- such as hard
acceleration from a stop, or light acceleration from at steady highway
speeds, since the car is in overdrive gear.

Problem with my 2006 Chevrolet impala
GM tech = jk
question = Why does my 2006 impala power steering not work anymore. It is grinding and
whining. I checked the fluid and it is low / empty. Where did the fluid go. Why does my impala
loose fluid.
JK:
A common cause for loss of power steering and the fluid is a power steering hose under the car.
As viewed from underneath, on the v6 there is a small 4 in. hose that connects 2 pipes. It is at the
intersection of the rt. (passenger side) frame rail, and the rear framerail. A new hose and clamps
are needed. Then fill and bleed the system.
On the v8 models, the entire hose / pipe assembly must be replaced. This is quite a big job. The
frame needs to be lowered and an engine mount removed. Then fill and bleed until the whining
goes away.
Best way to bleed is to get the front wheels off the ground, fill the reservoir half way, turn the
steering wheel to the rt. then to the left- all the way to the stops. Do this 10-15 times. Check and
adjust fluid level, then start the car.


2005 Chevrolet Impala.
Warning lights: Battery, seat belt flickers and a weird noise on the ac where you turn it on.
Repairs: Tune up changed the battery.
Question: Hi there. On my moms car its started to have problems when you start the car. It seems like the starter
is about to give up. Leave the car for a few seconds and it starts. The battery is new but when i was driving it to
see what it would do a weird noise under the dash where you turn the A/C on and the dash battery and the seat
belt light flicker and a buzzing noise. Her temperature gage dont show the temperature no more. It goes haywire.
I replaced the temperature sensor and it worked for a few days and it started to doing the same thing . Thanks
Ronald.
Answer: The problem with the starter sounds like it would be a bad battery, but you already replace that. This
may be a bad starter. The other problems with the lights in the dash and the noise under the dash, and the
temperature gauge problem, make me think it might be a BCM problem. BCM stands for body control module.
The BCM controls most of the dash warning light functions, gauges, as well as many other functions of the car.
But the BCM should have nothing to do with the starter. Be sure to check all the grounds on the engine. Follow
the negative battery cable. The engine and make sure it's clean and tight. And check all grounds you can find.
There are several on the transmission bell housing, and others on the inner fender wells under the hood. There
are also several grounds under the driver side of the dash. Most ground wires or black wires.
10-6-10 replace the starter too ,and still have the same problem its hard to start it takes several attempts until it starts checked all the grounds still have the same problem and it still does a weird noise too under the dash.

Getting confused on the starting problem. Is it cranking normally? Does it crank too long?
|
10-7-10 It's does it when you want to crank the car on the dash it shows the battery check the engine and the security but it wont crank it will start after few attempts.
|
Okay. If it cranks but won't start then sounds like you have a possible theft or security system problem. If it takes a few turns of the key to get the engine the crank, then this may be a problem in the ignition switch. This switch may also give you of the other problems you're having with the noise under the dash and the other lights. With the engine running, tap on the head of the Key with a small hammer to see If you can get the engine to die out or the lights to start flickering or any other odd electrical Issues

10-18-10 i took the car to the mechanics they put it on the computer and it showed the negative post loose stopped doing it for a while. They told me the security on the key might be the problem change it to the spare key and it started. Again with the same symptoms again you have too wait for a while until it crank over. Now on the dash it shows check engine light stays on you think it might be the ignition switch or the body control module? I for got to tell you also the car was on a fender bender on the left side but the air bags didn't pop out on the hit can that be another problem?
|
The security system on this car does not use a chip in the key, so changing keys would not matter. Sounds like an ignition switch or passlock cylinder-which is the key cylinder. Need to scan the computer for the check engine light first.

10-1-11 How do i repair a code P0420 on a 2002 Chevy Impala?
|
P0420 is usually caused by a bad catalytic converter.

11-14-11 CAR NOT STARTING FLICKERING LIGHTS HAD THE SAME PROBLEM WITH MY 2002 IMPALA. REPLACED STARTER, IGNITION, KEYS BLAH BLAH. FINALLY FOUND OUT IT WAS THE BODY CONTROL MODULE. HAD IT RE-PROGRAMMED FOR ABOUT $200, NO MORE PROBLEMS
|
11-25-11 Passenger side air bag light stays on and there is this humming sound coming from under the dash. This sound started when the light came on. Can not hear it until you reach 30mph. 2000 Chevy Impala V-6 3800.
