Alero :: 2002 V6 Engine Idles Roughly When Parked / Hesitation On Acceleration
Apr 11, 2012
Lately I have been having some trouble with 2002 Oldsmobile Alero v6. When the car is sitting in park I have noticed that the engine idles roughly, And when I try to drive it, the car hesitates on the acceleration every now and then. Also the emissions light (the orange one) will come on for awhile and then dissapear. At first I though it was dirty fuel injectors so I added some Fuel injector cleaner, but that has not fixed the problem. I was thinking the park plugs may need replacing?

My 01 alero 2.4l has some hesitation at takeoff, i have changed the plugs, boots, and fuel filter, and used fuel system cleaner. What could be causing this?

I have had this problem since day one. The idle seems to be very rough once you give it some gas and drive the car it runs smooth as silk. The dealer told me that is the wayit should be due to the narrow V6 with one head cylinder. I have had an 02 Passat V6 and I dont remember it having a rough idle.
My other issue is again since day one when I am moving very slow like when I am backing out of my drive way there is what I would describe as a grinding sound. It does it all the time forwards and back, all day not just the first thing in the morning. Again the dealer says it is normal.
I just had my first oil change about 2 weeks ago and was hoping these were just thing that would be addressed then but they dont seem to be better or worse always the same.

The dealership did my oil change. Afterward, the engine idled rough. I drove home 50 miles and called and they said they may have overfilled the engine oil. The dipstick level is about 3 inches over the fill mark. What damage could result and how to approach the dealer about it?

Changed the spark plugs, but the engine still idles rough while in drive and stopped. It's fine in park or neutral. P0303 popped back on today while warming up the car. Changing plugs significantly improved the idle...but it still is rough.

I have an 01 olds alero, I been having problems with the engine stalling out. i was told it may need a new fuel filter so I replaced filter and now it idles rough till it stalls. What to do next? I replaced the plugs 2 years ago also.

I have a 1999 F150 4x4 5.4, I pulled the heads due to blown head gasket. Prior to pulling heads truck started and run fine other than miss on #1 cylinder. I timed the engine according to Haynes manual and posts on this site. Truck is now hard to start and idles very rough. I does seem to smooth out when reving the engine and seems to have plenty of power. Cant find any vacuum leaks or unplugged wires.

Just as the title says, 214k great shape just wont get going more you mash the less it goes.... fuel pump already replaced, can undo battery and take a while to reset feels to do fine then goes back to bogging down... TPS ? idle air control?

I have a 2002 Camry xle v4. It has a hesitation at low acceleration. I've replaced EVERYTHING: Mass Flow Sensor, 2 O2 sensors, plugs, etc. This past weekend I changed the plugs again with a better quality than before and the hesitation went away....for 2 days! Now its back.

I own a 2010 Seat Leon 1.4 TSI 125hp 6 speed manual with 20000km (same engine, transmission, electronics as a Golf - 1.4TSI 123hp or Audi A3 - 1.4TSI 125hp, in North America you can consider it a poor mans VW or Audi, i prefer Audi LOL).
Ever so often maybe once a month when the engine is cold (usually during cold weather and in the morning) the following happens:
I crank the engine and get a really rough idle that's about 300-500rpm... the engine struggles and then shuts off after about 5-10 seconds and while this is happening the CEL an EPC light are on. after the engine turns off by its self, the next time I start the engine it works perfectly.
I have taken the car to a certified VW workshop since its under warranty (4 years) several times and they have found no fault codes. The second time I took the car they flashed the ECU to the newest software. The other day (Fourth time) after the above happened again.. they hooked up the car to the diagnostics tool in front of me to prove there are no fault codes stored. I left the car for testing and they came up with nothing.

I have a 2002 Hyundai Accent with a 1.5L SOHC and manual transmission, with 207,000 trouble-free miles on it.
I have recently noticed a hesitation under acceleration. It happens most frequently under hard acceleration under lower RPM, if I'm close to lugging the engine. The engine "hiccups," almost like it is missing a cylinder. It will hiccup 2-3 times until engine RPM's increase, then smooths out.
What the cause may be? Last changes: Plugs at 175K; Plug wires @ 160K, Fuel filter @ 100K, Timing belts at 60K, 120K, 182k. K&N air filter cleaned at 50K intervals, last time @ 200K.

I recently purchased a 1996 Ford Ranger with the 4 cyl. engine. The first 10 days I owned it it ran just fine. I then took a an hour drive to another city. After the first few stops there, as the temperature outside reached about 90, It started to sputter and idle very badly. After I got rolling it would would run fine. I decided to try to make it home. It ran fine at freeway speeds of about 70 mph. I had to stop once; it stalled out and would not start again. After waiting about ten minutes I tried again. It was still running rough, but I was able to get rolling and drove the rest of the way home without any problems until I was in town and had difficulty keeping it running at idle.
The next morning it ran fine again. A local mechanic changed the fuel filter, but the problem came back as soon as the temp neared 90 degrees. A mechanic friend who witnessed the problem said that it definitely sounded like a lack of fuel and not an electrical problem. Is there a way to troubleshoot without swapping parts? If the fuel pump is failing in warm weather, how is it possible that it runs fine at 70 mph, but not at idle? Engine temp gauge looks good. I did get one code after it died the first time (lean mixture, I think he said).

I own a 2000 Ford Escort ZX2 with an automatic transmission. I also own a 1991 Fleetwood Cadillac with an automatic transmission. Each car has its own situation.
The ZX2 idles high (about 1000 RPM) and rumbles pretty roughly while idling. I was curious as to what the cause might be.
The Cadillac has a blown head gasket and I was wondering how expensive and what would go into fixing this myself or just how much it would run going through a dealer.

It's a 05 Kia Rio. I've recently put a bit of work into it due to a few issues which were fuel related, namely replacing the fuel filter/pump. It also has brand new spark plugs. That solved the issue that originally put it on blocks for a few months and it ran fine for the past few weeks.
Today I went outside to drive to work and got the symptoms in the title. I know it's not a spark issue because it does start, and I used it on accessory to air up my tires this morning.
I'm just not sure where to go next. I've done a bit of searching and have found recommendations for checking the grounds and the distributor cap.
While running at rough idle, depressing the accelerator makes it die faster, rather than keeping it running. It rained last night and this morning. It's about 70 outside instead of the 80-90 it's been the last few weeks. No check engine light, but I've only tried to start it about 10 times.

I bought a 1987 Chevy Celebrity for $700.00. Initially it ran fine after just a slight hesitation when the accelerator was first pressed. With a little more gas applied it smoothed out and ran well. Yesterday I took a drive to the library. On the way the engine stalled. After a minute or so I was able to restart the engine and proceeded to the library. On the way home the engine again stalled. I was able to restart the engine but it idled roughly and stalled as soon as the accelerator was pressed even slightly. I tried varying the amount of gas applied from very little to pressing the pedal to the floor to rocking the gas pedal to no avail. So; idles roughly, stalls when gas is applied.

I have a Honda Accord EX 4 cyl. 2002. It has sluggish acceleration and hesitation problems. I put in new plugs and that improved it some. My mechanic says I should pay him to clean the fuel injectors. What will work best? What needs to be cleaned? Would new plug wires work? Gumout? Big differences in cost.

The problem starts after about 5-10 mins of start up and normal driving. First signs usually come leaving a stop light or stop sign. Hesitation, jerkiness, rough acceleration. It's usually slight, just enough to feel it. Soon it really shows up while keeping the truck at a steady speed, say 40 for example.
I finally heard what I would describe as a puffing air sound and figured vacuum leak.. finally! Nope.. it's coming from the rear underneath of the vehicle. I can't hear it in the engine, or the tail pipe.
2002 Ford Explorer xls 4.0 125k miles, I've replaced the air filter, egr valve, pcv valve, cleaned the maf and covered about every hose I can reach with carb cleaner checking for a vacuum leak. I've yet to try some of the other things due to hearing that puffing sound.

I have had a problem with my 99 Alero for some time. It is a 4 cyl 2 door and there is a hesitation that comes and goes I have changed the plugs,fuel filter and air cleaner and will still do it from time to time. I have also tried different grades of gas and injector cleaner.
It seems to do it most when we are going up an incline just before it shifts when the motor is getting the most load on it but it will also do it when I start it up like it has a miss. As I said this comes and gos and no lights have come on so I'm not sure if it has stored codes.
Recently I have tried Outlaw super concentrated fuel injector cleaner and I have not had the problem for the last week or so?

Problem: The care currently has a hard start, and a fluctuating idle. I bought the car a year and a half ago it still has low miles about 94,000. The care used to start fine but had a fluctuating idle in the range of 750 to 2500 rpm. My brother who is a mechanic and doesn’t live near, do all the gaskets when he visited. Then the idle fluctuation dropped to 750 to 1000rpm, when the car rpms fluctuate there is a whirring sound I can hear from the cab, like a pump or pull system. On occasion there is a vibration as well but it is inconstant and irregular. Fuel pressure seems to fluctuate as well. If the car will not start I give it a little gas and it will run fine after a minute or two, but then the idle starts to fluctuate.
No fuse issues I can tell and relays seem to be fine.Checked for lose wiring connections found, none. I have replaced:
- Hoses and gaskets
- Starter motor
- Battery
- Fuel Pressure regulator
- Fuel Filter
- Spark plugs and wires
- TPS
- Idle Air control Valve
- Crank shaft sensor
- PCV.
Right now I’m thinking it could be the fuel pump (a nightmare to change on this car), a fuel injector failing, and the ignition switch.

My '06 Pt Cruiser A/C works fine @ speed, but idling and @ stop lights it blows moist warmish air and idles roughly.

I have the strangest problem on my 2006 Audi A6: whenever I fill up my tank with gas the car has a very hard time starting. This has happened 3 times in a row now. I run the tank fairly low - to about 1 quarter tank or a little lower but never to empty....then I fill the tank. When I get in the car to start it, the engine just keeps turning over trying to start but will not start. Then I stop trying, let the ignition rest for a bit, and try to start it about 5 minutes later and it starts just fine on the first try.
What could be causing this?One thing that has also started happening around the same time as the problem above is that when I'm idling at a stop light, I notice the car may start to idle roughly and seem like it is about to die out. I am the first and only owner of this car...I take good care of it and am an easy going driver. But I do drive a lot and have about 200,000 miles on it after 7 years.
