Alero :: 2002 V6 Engine Idles Roughly When Parked / Hesitation On Acceleration
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?

It'll do okay when I am not flooring it, but when I do floor it there's a pretty noticeable lag and then VROM it'll take off like a bullet... This car has a manually operated throttle control, are there any adjustments I can make to make the truck more responsive? 2.4L 4Cyl....

Last night i noticed a slight hesitation during acceleration. Today i had driven around in town for awhile and did not notice any hesitation. When i got onto the interstate I pushed down the peddle to pass someone and it did nothing, I let off the gas and back on and the car bucked pretty bad. All the way home it has issues when I pressed on the gas but did fine at cruising speed. I would think a fuel filter would have been a slow progression issue so I am thinking maybe it is a sensor. I sprayed carb cleaner around vacuum hoses today and did not notice any surge so I think I eliminated a vacuum issue.

Passat (B5) :: 2001 V6 - Engine Hesitation / Misfire On Acceleration
I have an 01, early model, AWD Passat wagon, v6, GLX and when I accelerate from a standstill or a slower speed, the car hesitates slightly and coughs(?) and then catches on and accelerate. It doesn't actually backfire or misfire.

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?
Elantra XD (2001-06) :: 2003 - Hesitation On Acceleration / Resistance On Pressing Gas Pedal
My 2003 Elantra has multi spark (quad) electrodes? I have a hesitation on acceleration problem. Also feel resistance when pressing the gas pedal. I am going to change the plugs and wires. Just wondering if the type of plugs may contribute to the problem.
View 9 RepliesAlero :: Intermittent Throttle - Hesitation Occur On 2000 GLS V6
I have a 2000 Alero GLS V6 with 215K miles. The car has been experiencing intermittent throttle issues where it will hesitate slightly. Immediately after this hesitation the trac control trio of lights come on. I don't think this is the bearing as there is no wheel noise to accompany this. Also the trac control lights don't remain on when you start the car the next time. If this hesitation occurs when using the cruise the cruise control will be disengaged.
I also scanned the car and pulled a P0341 and P0440 code. (cam sensor and evap). These codes have existed for the last two yrs long before the throttle hesitation issue has cropped up so I don't think it is related.
Toyota - Corolla :: 2002 - Hesitation After Stopping At Light
When I stop for a few minutes, such as at a light, or making a left hand turn, my car hesitates. The place I take it to cannot find the problem and they have replaced a lot of things in it, but still no change. It is a 2002 car, so it is a little older, but I have always kept it in good shape, it has 65,000 miles on it.
View 6 RepliesFord 6.0L Power Stroke Diesel :: Intermittent Hesitation After Stopping At Light / Stop-sign
Trying to troubleshoot a very intermittent (has happened on two different occasions during the last 1,000 miles) hesitation from a stop-light. I've been recording engine parameters (Torque application) on both instances as these have been during longer trips after a period of highway driving. 2004 Excursion, 112K miles.
This feels kind of like severe turbo hesitation (4 to 10 seconds trying to start out before it kicks in) but I don't think that's it. The turbo is a new PowerMax turbo replaced 5 months ago. VGT readings seem pretty normal. The EGR valve is new -- the first instance was with the old and the second was with the new. I've also recently replaced the EGR and Oil coolers (before this).
Here's what's interesting in the captured data though... Normally when I coast into a stop-light the indicated engine load stabilizes at about 40-50% and VGT moves to about 65% to 70% at idle. The two different times this happened (actually multiple times at stop-signs/light close to each other over 5 minutes or so for both of these), when I have coasted to the stop, the engine load increases from low values during coast-down (0% during freeway coast-down or 19-30% during other coast) up to 99.6% (or other similar high values) at idle and VGT seems to be full closed at 85%.
There is absolutely no response to the throttle in this situation for 5-10 seconds. I've either been goosing the throttle a bit or putting it neutral and revving it up first to get things going again. When it finally catches and starts accelerating with power, indicated engine load drops to 50-60% again and VGT opens up to 40-60% or so. None of the other parameters I've been capturing seem to read strangely during this that I recognize. No issues observed during cruise and power seems good. No pending DTCs or engine light.
Here's what the data points I'm capturing (once each second):
Boost
Calibration Input Volts
ECT
EOT
Fan RPM
FICM main volts
Fuel Injector pulse width
ICP
ICP Volts
IPR Duty cycle
RPM
Engine Load
MAP
Trans Temp
VGT Duty Cycle
EBP
EGR Commanded
EGR Error
Added today but not captured during these issues yet:

Touareg :: Hesitant Acceleration After Stopping At A Light Or Trying To Get On The Highway
I just recently purchased an 05 Touareg V6 and I am a little concerned regarding the acceleration I am getting like after stopping at a light or trying to get on the highway. It seems that it takes this vehicle about 5-10 seconds to realize that it needs to get moving. However, after it does realize what it needs to do, the acceleration is fine. I was told different things such as it could be the turbo system and one thing I find very hard to believe that this is a characteristic of all VW's. I like my VW and don't want to get rid of it but would prefer better acceleration
View 2 RepliesAlero :: 2001 - Key Won't Turn At All In Ignition
Got a 2001 Alero 4 cyl. Couple. Almost a month ago that car wouldn't turn over. Did the 10 min passlock procedure and it started. Been OK til today. So now the key won't turn in the ignition. Won't turn at all. Steering wheel is not locked, car is locked in park. Tried to turn it while moving wheel, shifter, etc. to no avail.
Is this a bad ignition lock cylinder? If so, I've read some procedures on how to replace this thing. It looks horrible. And it seems that one needs to turn the key to get the cylinder out. Is this correct? Remember, my key won't turn at all. Also, is there any way to key it to match the existing keys without taking it to a stealer/dealer? I saw a part on Rock Auto that comes with 2 keys. But I guess then the ignition keys would be different from door/trunk.
Alero :: 2001 - AC Is Blowing Fuses?
I have a 2001 Olds Alero. The AC compressor went out so my father in law and I replaced it. It worked fine for about one month, not it keeps blowing the a 10 amp fuse (can't remember which one at this moment, my wife is at the store with the car). I have been told that it is a bad wire, I can't see any pinche wires and have looked up to where the wires go into the tape/plastic casing. I have also been told that it is the compressor that is doing it (the parts store said this was not the case... I think they just don't wanna warranty anything).
View 12 RepliesAlero :: 2001 - Intermittent ABS And Trac Lights
2001 Alero ... I've read about the sensors and wiring on the hub causing the ABS and Trac lights. They come on with the Service Vehicle Soon light, sometimes, when I start rolling.
I had a mechanic look at it, and it was not giving any codes. He tried to turn off the lights with the machine, and they would not turn off. He concluded that it was a computer problem. He said that a ground causes the lights to come on, so it could be a wiring problem.
Why would my lights come on intermittently? Do I have to wait until they come on, then immediately pull over and check the sensor or hub? Is there any way to check this on my schedule?
Alero :: 2001 - Dash Lights Not Working
The backlights or whatever they are called that light up my spedometer and fuel gauge, etc, are not functioning. Other lights such as engine, oil and park/neutral/drive work just fine, as does every other electrical system as far as I can tell. Is there a specific fuse that I need to check, or does this warrant a trip to a repair facility?

View 2 RepliesAlero :: 2001 Overheating And Sputtering - Coolant Leaking
I have had my 2001 Alero since it was brand new off the lot. It has been a strong running car. It has had done work on it, most recently the mechanic I'm using has replaced the intake gasket, thermostat, hoses, and coolant reservoir because of the coolant leaking. After all that still having problems with the coolant leaking (but apparently not mixing in to the oil)....I've just been putting water in and I have to stop after driving about 10 minutes to refill the reservoir.
The mechanic was going to replace the cooling fans because he said they weren't working but then he hooked up a sensor machine and there were no issues, so he ended up replacing the radiator because he thought there might be a blockage causing the water to boil back up into the reservoir, and the car overheating. The car drives great, but after about 10 minutes there is a type of sputtering. The mechanic is saying that he has replaced everything that can be replaced in the cooling system and that he thinks the head gaskets are bad.
Oldsmobile - Alero :: 2001 - Fuel Pump Not Always Turning On
My 2001 Oldsmobile Alero only starts about 50% of the time and has also turned off twice when I was driving, once in a parking lot and once when I was stopped at an intersection. It cranks and the radio and lights work. The fuel pump was replaced two years ago and sometimes you can hear the pump turn on and sometimes you can't. My husband replaced the fuel pressure regulator and has switched out the fuel pump relay but it hasn't fixed the problem. Based on this, can you tell whether the fuel pump might need to be replaced again or whether it could be something else connected to the fuel pump, or something else entirely? The fuel pump is under warranty at the dealership that replaced it, but unless the fuel pump is bad then I don't want to go back to this dealership and would rather go to different repair shop.

View 4 RepliesAlero :: 2001 GLS Won't Crank In Freezing Temperature Or Colder Humid Air
3.4 2001 GLS.. When it's near freezing out there and humid, the car won't crank, it's not the starter since I can get it going by jumping it.. I'll just leave the car alone, go to work and start it later and it will start just fine for who knows how long..
It did it 2 days ago, I didn't notice any security light on solid or anything else whatsoever but I think I have an electrical intermittent problem that gets worst with humidity or colder humid air.. I've read most topics here but I still can't figure it out so far.. Inspecting the fuse box showed that the positive wire was surrounded by green dust, I've cleaned that.. My horn sounds anemic at times when I use the remote door lock..
Is there a relay dedicated to crank the car, I mean, sending the power to the starter solenoid? I just don't get the relation with that near freezing or freezing temperature thing..
