Impala - Chevrolet :: 1972 - Stalls When Idle?
Jun 27, 2011
I've been trying to get her up and running for awhile now in order to sell her. I bought the car from a neighbor who never drove it (only 50k miles on it) and my dad had a great idea to get some new parts for it...I just wanted the car as it was... So we replaced the original carb for a newer carb and my father did all he wanted to do to it (I do know he took off the distributor, did some thing with the clutch, and replaced the fuel line to the distributor).
Well, when all was said and done (after a year and a half), the car is back up and running BUT when it sits idle it stalls. It will only stay running when you keep on the accelerator to rev the engine. As soon as you let up, the RPMs drop and she stalls. He's not sure why it's doing it, and I'm even less sure.
What are some reasons/causes/possible fixes for this?

My 2005 Chevy Impala is taking a long time to crank. Now after 10 minutes or so of either idiling or driving, the car stalls out. I am able to restart it. Replaced the battery and no change. Lights are not getting dim in any way so I figure it's not the alternator. Could it be a bad starter?

2009 Impala, 6 cyl., 32k miles, with the engine warm and running below 1000 rpm I only get cool air entering the cabin. As soon as I rev up to 1000 rpm and above heat enters the cabin. The coolant level was a little low and I added about 2 cups. I haven't driven it since adding the coolant but I doubt that is an issue. Since the day I bought this vehicle (at about 16k miles) I could detect a whine sound coming from the engine compartment at start up. This may have something to do with this problem, but until just recently the heater did work fine. The A/C works fine. Thinking maybe a water pump?

I have an '01 Impala, 3.8 engine with 200k miles. Whenever the engine idles, at a stop, or in a parking spot, the idle will drop, then the car will stall. It will start right back up, but unless you are actively pressing the accelerator, the same thing occurs. There's no sputtering or performance issues, and nothing to indicate that it's about to stall. I've replaced the IAC valve, AND the EGR valve. Still having the same issue.

2004 Trailblazer 6cy. 2WD - has been experiencing a very rough idle, engine shudders - no matter how long it's been warmed up. Wants to stall off red lights and at very low speeds. Not throwing any lights yet - but the speedo is out ( a cam shift typical problem for this car) so I don't trust the console for lights. Worse when the heat or air is on. Rides fine with more gas/higher speeds. Definitely worse in colder temps but continues even after 40-50 mins of driving. I've heard a number of things, but can't afford to fix them all. I've heard plugs, dirty throttle camshaft, sensors, cam actuator solenoid, etc. All seem to have people who said it fixed and didn't fix the issue. Worried I'm going to stall pulling off a stop and rear end someone any day now. Where do I start!?

I have a 2004 Chevy Impala with 100,000 miles. A couple of times in the last year the car just wouldn't start. Everything comes on lights, radio, etc. but it doesn't even try to turn over. I took it in twice and the mechanic of course couldn't find anything and it didn't happen again until recently. It has happened 6 times in the 3 weeks. It runs fine, has a new battery. Mechanic keeps telling me they can't diagnose it until it happens when they have it. I have had it towed to them twice when it has happened and of course when they try to start it it starts beautifully. Mechanic is guessing it may be the starter but doesn't want to assume. My dad said he heard a caller this past weekend on Car Talk with a similar problem and they were told it was the crankshaft position sensor and to not even mess with the starter.

Sometimes I turn the key and nothing happens except the lights come on but nothing happens. Then if I press the brakes, move the gear shift from park to neutral and back it might start. Sometimes I have to repeat the process a few times and twice I was stranded! If it starts then something unusual happens if I am going in reverse and turning the steering wheel sharply to the right the is a loud grinding, whining sound. It's not like the sound of a whining power steering noise.

On my newly purchased 2003 chevy impala i believe my starter is going out. Outside of turning the key and nothing happens how does a mechanic test or verify its the starter?

I drive a 2004 Impala with just over 100k miles and sometimes it just will not start. All the bells and whistles work fine but it just doesn't start. The security light flashes 3x and then shows a picture of the battery. I replaced the battery and it seemed fine for a few months, but then did it a few more times. I've heard of people spending up to 3k dollars replacing various things, making no difference at all. On most websites everyone seems to thinks it's the GM Passlock system...

Recently the check engine light came on and coded out to the mass air flow sensor. I changed the sensor and cleared the fault code, but after doing so the car wouldn't start. After many failed attempts to start the motor, I disconnected the positive lead at the battery and reconnected it a few minutes later. The car started and ran smooth, however the check engine came back on and coded out to the mass air flow sensor again...
I let the car continue to idle and disconnected the lead at the sensor how the motor would react; it continued to run smooth....I then reinstalled the old air flow sensor and engine continued to run great...So with all this said, car runs great when check engine is on and code is not rest, however, car will not start upon clearing the code and resetting the light......is it safe to assume the computer is going bad and needs to be changed?

So this car has been having overheating problems since I first purchased it. I've operated it, but I've had to keep the heat going full blast to keep the coolant tank from overheating.
Last night I was driving on the interstate, and it began to overheat. It was running hot for maybe 3 minutes before I was able to pull over. I let it sit and cool for probably about 20-25 minutes, pulling over on a dark portion of the interstate, before I started it with no problem and moved it to a safer location (it ran hot again, but this was maybe for 30 seconds before I pulled over and shut it off.)
I let it sit for a good hour so that it could cool all the way down from 260 to 140. I then attempt to start it. It turns, but does not start. At this point, I call a tow truck to come for it. About 30 to 40 minutes after this, I start the car again. It starts with no problem. I put it in reverse, and roll it back to see if there are any leaks. There's leaking from the coolant tank...quite a large puddle. I refill it with distilled water and it leaks some more but sits mostly. I then start it again, and roll it forward. The tow truck arrives maybe 30 minutes later, and I attempt to start it to line it up behind, but it turns and does not start. We have to put it in Neutral and turn it to get it in line for the tow truck.
We get to my destination, probably about a 40 minute drive, and he unloads it. I attempt to start it...again, it turns but does not start. This morning, about 8 hours after that, I try to start it...it does not even turn.
The oil is just fine, the battery is not dead (lights/radio/horn/etc. works), but the battery does seem weak since the dashboard lights are dimmed no matter how much I turn them up. Even though the coolant tank has been somewhat depleted, it was never close to being empty or bone dry. There weren't any "knocking" noises, there was no smoking or anything from either the hood or the exhaust.

I have a 2007 Chevy Impala with the 3.9L. It has just over 110,000 miles on it. I've owned the car for about 5.5 years. Back in 2012, I took the car to a local transmission shop. Here's the reason: Let's say the car has sat overnight. I start it up (regardless of the season) and go to the stop sign at the end of my street. When I go to accelerate, there will be a very short lapse and the car will seem to jerk into gear then go. This is a very intermittent problem and does not happen every day. The car will do this for a bit when accelerating from a dead stop and then the problem goes away.
The trans shop said the transmission needed to be rebuilt. Guy told me they've seen problems with the Impala transmissions and, if I remember correctly, that the parts used inside aren't the best. Looking for a second opinion, I took the car to a Chevy dealer. The dealer was not able to experience the jerking. I had the trans service done (80,000 miles at the time). The problem persists to this day and has not, noticeably gotten worse. I decided to take the car to another dealer last week. Same thing: the dealer could not create the jerking issue. Again, this issue is very intermittent.
I am not sure what to think or do at this point. I called a couple shops around town and have gotten the following advice/information:
1) Bring it in and we can see if we can recreate it, but can't guarantee it.
2) The transmission needs to be rebuilt (this without even looking at the car).
3) Wait for the problem to get worse so that it CAN be diagnosed properly.
One guy said he didn't trust the dealer mechanics, that they "just drive around the block once." I am not sure what to do?

My 2005 Impala is overheating , sometimes, and only for a minute. (When it goes into the red, I pull over and turn car off for a few minutes.) The needle fluctuates, though. I read old posts, but my mechanic tried them. Here's what's gone on so far:
Replaced thermostat, flushed / refilled antifreeze , car worked fine for a day, then it started again.
He then took an air pocket out. He took it for a drive, it was fine. I drove it for a day, it was fine. The next day it started up again (needle quickly fluctuating, sometimes needle slowly fluctuating).
He replaced the upper radiator hose. He then drove the car (local and on highway) for 2 1/2 hours, it was fine. I picked it up and it was perfect for the rest of the day/evening. This morning, after driving about 8 miles, it started again. I'm dropping it off tonight. He said it is hard to know exactly what it is without trying things. He said next he would try water pump or radiator.

Without any particular known triggers, the car either will not even turn over, or sometimes the electrical will come on, but the car won't start. Wiggling the keys and steering wheel don't necessarily work, and I can't shift it at all when it's not on. Took it to the garage and left it there for days -- never did it for them. Starter? What to do?

I have a 2009 Chevy Impala. It has 28,000 miles and since November my gas mileage averages between 20-24. I took the car to the dealership and they say nothing is wrong. This car was titled in Hawaii. I live in Wisconsin. Could the colder weather have something to do with the mileage or what else could it be?

I have a 2008 Chevy Impala. I've owned it for 14 months and put about 12,000 miles on it in that time. It's had basic servicing (rotations, oil, oil filter, cabin filter, etc. changes). It hasn't given me problems---but suddenly I have one and I'm not sure how major it is.
I made a drive from New York to Western Mass yesterday...couple hundred miles, but nothing huge. It drove fine all yesterday after I arrived...again, no problems. This morning, I went to start it...everything's okay. But then I went to shift it out of park...the button will not depress. I restarted a few times...no luck. I kept trying to depress the petal to shift it; I couldn't even shift it into neutral when not started. I am not sure what in the world is going on.
I've read numerous forums on this---it seems to be a common problem with these cars. What's not so clear is what to do with this. Responses range from---stick a screwdriver into some hole all the way to just go on and junk the car, it's useless. That's why I am coming here to get clearer guidance on resolving this problem, hopefully in an economical way.
