Chevy Impala Sputters- Power Steering Leaking

2000 Chevy Impala Engine size = 3.8L.
Repairs for this problem = cold air intake replaced. 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.

Answer:
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.

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.

Answer:
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 down to 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.


Question: I 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. 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.
 Answer: 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.

I took my Chevroolet Impala 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.

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

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.
