Impala - Chevrolet :: 2005 - Gas Smell Both In And Out Of Car When Idles But Only After Some Driving
Feb 11, 2014
There is an odor when it idles both in and out of the car but only after some driving - if I sit there a while the smell goes away. It is most noticeable when I get off the highway on my way to work and sit at a stop light. If i have to sit and wait for someone, the smell dissipates. I cannot find a leak. There is a performance issue but I'm not sure if it's related. At highway speeds it is having trouble accelerating - if I'm at 55 and want to go to 65, it'll go but it feels like there's resistance, almost a pulling, it causes the car to rock back and forth a bit - again it only happens at higher speeds. It has 140000 and is in good shape (except for things mentioned). The last repair was a water pump replacement about 4 months ago.

Recently I've been noticing a gas smell after parking my car after the drive home from work, but engine performance and mileage efficiency didn't seem affected, and I found no visible evidence of leaking on the ground (nor in the engine, but I likely don't know the right places to look).
Today, with the engine running, I looked around the engine to see if I could locate any gas leakage -- I located the fuel pressure regulator (I think; a golf-ball sized acorn on the right of the engine with a hose coming in the top and a pipe coming out the bottom and going down and to the left) and didn't see any leaking during my brief test. I'll check it again after my drive home tonight.
One new thing I did discover, though; while in park, when I slowly pressed on the accelerator, there would be a point where the engine started losing power and going into a rev/slowdown cycle: about a second or two of revving, then a half second of slowing down. This was while cold and in park; I've not experienced this in normal driving.

I purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.

I got this car from someone and I just noticed none of the gauges on the dashboard work! Everything else works fine and the mileage still shows, engine notifications still show, etc.It's a 2005 Chevy Impala. What might be wrong?

I replaced the thermostat, flushed the radiator and have the same problem. it can idle just fine but it gets hot driving less than 15 minutes. There are no visible leaks.

About 90% of the time, my gas gauge on my 2005 Impala works just fine. However, sometimes on hot afternoons it has problems & it doesn't read accurately. For example, I will have a nearly full tank & the gauge will show 1/4 to 1/2 full, depending on its "mood". If I drive the car somewhere & turn it off, everything is fine after I re-start it. I have to drive it somewhere though. If I start it, turn it off right away, and re-start it, it still reads inaccurately. The car runs fine & there no warning lights are lit on the dash.

I recently had an issue with my car overheating so I changed the thermostat. About 3 months later it happens again. I know I need a new tensioner arm but I decide to wait on it. I take it to a place and have the radiator flushed and the guy calls me back to the garage and says your belt fell off... i was like o man, so he showed me how it would slip off the tensioner and i said ok and put a new tensioner on. He called me back and said he found a new problem my crank shaft pulley was wobbling a little. I didn't have enough money to have him check it out further so he said he would just finish the flush and go from there. after he finished the flush he said there is still a problem with the heating on the car. He didn't know if the problem came from the pump, the t stat, or something like a sensor. and it would cost alot in research time for him to find the problem and fix it. so i am going to take it to another mechanic. I have replaced the pump about 2 years ago, I replaced the thermostat about 3 times before the flush over about 1 years time, i replaced the stepper motors on the gauges since they went bad. and now I am at a loss on what to do next. I just wish that click and clack would come fix my car.

I inherited this car from my parents a couple years ago with about 80,000 miles. It ran great for awhile, then the air conditioner and the gauges would quit working while driving. After a few minutes they would resume working and everything would go back to normal. Now it will start sometimes and will not start at other times. I have replaced the battery two times and it seemed to work for a short period. I have had several mechanics look at it. After checking the code and replacing a fuse or sensor and replacing the ignition switch the car is still doing the same thing and no one has a clue what is going on. It seems to me that it may happen more often when going over a bump. What could be causing this?

I have a 2005 Impala with the 3.4 engine and 118,000 miles. About 2 years ago I had a code P0141 and since we didn't know for sure which oxygen sensor was out we replaced both of them. The P0141 code did not stop occurring after both sensors were changed. I read on an Impala forum that if you didn't replace the sensors with AC Delco the codes would continue so I didn't worry about it until my gas mileage starting going down recently. I ordered new AC Delco oxygen sensors and my husband replaced them Saturday, the old ones were sooted up pretty badly. Today a new code appeared, it is P0140, O2 sensor circuit no activity. What the problem might be now.

My 1992 chevy s-10 is running really bad it idles high ( like around 2000 rpm to 1000 rpm) it starts high then slows down. Then when i drive it, it kinda stumbles. Iguess u can say it makes all kinds of noises and beats and bangs and if I am going up a hill some times it shuts off. It has a manual trany and a stock 4.3 motor. I need the truck to get back and forth to work....

For the past several months, every now and then while driving the engine power will reduce and the Driver Information Center will display two messages: "Service Stabilitrak" and "Engine Power Reduced", and the ESC and Check Engine dashboard lights will come on. Shifting becomes rough especially between 1st and 2nd gears. After turning off the car for 10 minutes or so, the engine power will be restored and the ESC light goes out but the Check Engine Light remains lit. After a day or so the Check Engine light goes out. Otherwise the car runs normally. This happens at least once on every long trip where I am out on the highway - sometimes multiple times on a single road trip. It does not happen in short trips around home.

I used a OBD scan tool and all it told me was my idle air control system rpm is lower than expected and my evaporative system has a high purge flow. What this means, can I fix it or do I have to send it to a shop. Also when idling the short term fuel trim 1 is at -3% whatever that means.

My 2003 Chevy Imapala went over some large water puddles and shortly after a check engine light came out. My local auto store did a check and stated there is a possible problem with a senor. If the senor got wet, could it even give the computer a good reading? Would it probably give a totally different reading once it dries?

Last night at 2am and it was about 10 degrees out (I say the temp because it might matter?) I started my car, let it warm up to normal running standard and backed up. My car moved backwards but the wheel would not turn at all. I pull forward into my parking spot and noticed that the wheel is extremely hard to turn left or right... almost impossible.
I check under the hood and noticed that my car was leaking something onto the group but it was dark and I couldn't quite see what it was.
Checked this morning and I found that my power steering fluid was completely empty. I had a half bottle in my trunk and put it in my car, then turned my car on. All of a sudden I noticed that the fluid is leaking onto the ground. Not really leak, more like a slow/medium pour and the wheel still wouldn't not move.

1989 Chevy Corsica has lower than spec fuel pressure, but exhibits no problems under heavy acceleration at highway speeds (passing), so I'm not sure it's a problem (yet). When cold, seems fine. As warms up, starts to surge somewhat when driving around 30MPH and idles rough and stumbles when starting from a dead stop. No blink codes (except code 12) and no check engine light. I suspect a sensor, but which one(s)? Low fuel pressure or bad sensor?

I have a 2004 Chevrolet Malibu Classic with 173k miles on it. Car runs great. AC works intermittently sometimes, but it's not a huge issue. It kind of stops if your in city traffic, but at highway speeds, AC is dependable. Particularly when running AC (or it may just be because it's the end of summer), I notice a smell on my clothes. It's not necessarily like standing beside the exhaust pipe, but after driving for a while with AC, I notice it. I also sneeze some when this happens.

My 04 Chevy Venture has started smelling of gas when I drive. It doesn’t happen all the time. I can drive to a destination and smell nothing, park, and a few moments later leave and smell the gas. I have had the fuel lines checked and was told there are no leaks. The smell is stronger when I have the vents pointed at me, but if I switch to the floor vents, it diminishes.

I have a 2005 Audi Allroad and sometimes when I get in the car after work there is a strong natural gas smell in the car which goes away after I drive away. I park in an underground garage so for a while I thought it was the garage but I have smelled it on the week ends now too occasionally at home parked in the drive way. I also have a freakishly accurate sense of smell and have often detected smells others could not. I am sure it is not a gasoline smell but a natural gas like smell. What this could be?

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.
