Question about 2000 Chevrolet Impala

2000 Impala Stalls

We have owned 2000 impala for 4 years. Last week we had to replace battery (replaced at repair shop). Yesterday car stalled and died twice with my husband. Car will start then die. Husband found that a crimped terminal to the upper underhood fuse block had broken from its wire (probably by people installing battery). He replaced this hoping it would solve problem, but it did not. When car is running it feels like it wants to "surge". We recently had mass air flow "module" replaced along with ignition switch as car would refuse to start, then start after 10 minutes. Any ideas on problem? I am seeing a lot of people with the same problem on some internet postings, many who have been unable to get a "fix". Any ideas greatly appreciated.

It could be either the IAC Idle Air Circuit which would cause it to stall during engine load changes . It could be the egr valve. But i would check for leaking vacuum lines first. The IAC control comes closer to your problems you have written here

Could possibly be the crank or module sensors. I have seen the same postings and this is what one person had done to solve the problem. These can easily be determined by having the computer scanned if there is a code which there should be or hooked to a computer when the problem happens. Hope this was some help.

I had battery check last week because it wouldn't start now it stalls when idiling


Check the alternator to see if it's working. If the battery is 3 years or older then you should have it tested too.

P0171 and P0174 are lean codes. There is likely a large vacuum leak or the MAF is bad.

Try starting the car and wiggling the connector for the MAF sensor. Also try tapping the MAF sensor. If the idle changes or the car stalls replace the MAF sensor.

The second shop should recognize that these codes don't have anything to do with the ignition module.

My 2002 3.4v6 chevy impala stalls out when it hot out and will have to wait about 20 min before its starts up again


Check Fuel Pressure with a gauge when it does run

Fuel Pump may be failing

Check that the Cooling Fans come on
& it isn't going into fail-safe, if that applies

Check coolant,not just look at recovery tank
Remove radiator cap & look

Have to have your car checked over once
or twice a year at a repair shop

Not just wait for break down maintainance

Chevy Impala stalls while driving down the road, then restarts immediately, after surging. Replaced the battery yesterday,and now the service traction system light is coming on. Very dangerous stalling at...


First off I would suspect the fuel filter. You didn't state how long it runs before it stalls but I think it's not more than 10 minutes or so. It could also possibly be the Mass Air Flow sensor, but I really don't think that is it. If it was sputtering then I would check the Exhaust Gas Recirculating valve for clogging - a hands on diagnostic is really the best bet, unless you haven't changed the fuel filter in a while, in which case I would change that just for general measures and improved MPG. I recommend going to your local shop and have them clear the codes from the computer to see if the service light was just a glitch from changing the battery! If it comes back then you'll need to have the computer scanned to see what codes it's throwing out. Hope this helps!!

2003 impala stall out of nowhere while driving what to do?


Fooling with the battery cable only fixes the problem because it wastes time while the car is flooded. Instead... pretend like you are fooling with the battery cable and then after a couple minutes, try starting the car again. It will start.

There are many things to check. Most commonly, the crankshaft position sensor. Unfortunately, it's the hardest to replace. It will take about 1 hour to replace if you have the right harmonic balancer puller. Other things to check that are easier...

2 Camshaft position sensor
3 MAF sensor
4 IAC
5 Fuel pressure regulator
6 Vacuum leak

Most of the time this problem is fixed by replacing the Crank sensor, but not always. Lesson learned here... Never buy a GM again.

Luckily your heated seats haven't caught fire and burned your clothing and your back. If it ever does happen... do yourself a favor, let it burn and get a new car (not another GM.)

2003 chevy impala ls starts then stalls


I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
