Buick - Century :: 2000 - Transmission Will Shift Hard After Stopping At A Light Or Stop Sign
I have a 2000 Buick Century that only has 70000 miles on it. I have an issue that when I drive the car for a while, the transmission will shift hard after stopping at a light or stop sign. It only does it through the first three gears. If I shut the car off and let it sit for a few minutes and start it back up, it shifts fine through all of the gears. I have not had the change to change the fluid and filter yet. The fluid looks clean and is always full. I have read that there has been a common problem with a pressure control solenoid in the transmission needing replaced to correct the hard shifting. I am not getting any kind of error codes from the PCM, so I am not sure.
View 4 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

Ford Super Duty (1999-2016) :: Tranny Would Not Shift Back Into Drive After Stopping At Stop Sign
I need to solve tranny problem, it started out a while back, would not shift back into drive after stopping at stop sign (after driving fine for about 20 miles) thought maybe dirty filter so did fluid and filter change seemed to work for a while then started again noticed it was mostly after using cruise control, but u joints were very bad, so replaced 2 of the 3 and worked fine for about a thousand highway miles, then got really bad. Now when I check the tranny fluid cold and /or hot it is way up on the dipstick. Took to ford dealer in ladoga, lied and said no speed sensor codes, but list on the paper he gave me had all kinds of abs and a p500 code.

I have noticed, in my 2012 Elantra with 32,000 miles on it, that my car is shaking at idle. I'll be at a red light or stop sign and the vibration is SUPER annoying. I have had it tested at a Hyundai Dealership. They couldn't "replicate the problem" and nothing it wrong with my car.
I may be trading this car in for the Veloster Turbo. I'm tired of how slow this car is. I know I sacrificed speed for gas mileage, but I have a question, does the Veloster have this problem as well?
Elantra XD (2001-06) :: 2002 / 2.0 - Excessive Vibration At Light Or Stop Sign
When @ a light or stop sign the car vibrates excessively to the point it makes my daughter sick. I do feel it vibrating but it doesn't bother me but something is definitely wrong. There are no engine lights on, I can hear the top end tapping and clattering, I did check the valve clearances which seem to be barely within specs. She says it vibrates worse when the tank is full. She also said when the tank is full the front end shakes driving down the road. I'm kinda wondering the front end shaking with a full tank might be the rear struts.

I recently bought a 2006 STX with the 4.6 engine. Occassionally, when stopping at a light, the engine will stall. I took it to the dealer where I bought it and he put it on the computer and found that once on a test drive the RPM's dropped to 490, but it did not stall. He said everything checked out fine and thought it might be a carbon build up, since the truck only has 27,000 miles on it and was driven only around town. He suggested a couple of tanks of higher octane fuel and a fuel additive to remove the carbon.

I have a 2010 Elantra Touring, manual transmission. At about 30,000 miles it developed an odd feature which continues through the present time with just under 50,000 miles. At any speed and on any road from time to time I suddenly get a loud interior noise like driving right next to a train running on a track. There is no vibration, just a very loud rumbling sound drowning out the radio. Goes away after a few minutes, does not recur on the same piece of road, same temperature, or same time of day. When it first occurred the dealer inspected it and though they could not hear it they divined that the aftermarket cruise control mounting bracket had become loose and was vibrating. They tightened it and the sound went away for a year but is now back louder than ever. I checked the bracket and it is tight and the dealer can find nothing loose. The bumper to bumper warranty is about to expire. I am thinking a crack in a steel bearing surface or a bad weld causing a vibration running through the body. Again I feel no actual vibration through the steering wheel.
View 12 RepliesHyundai - Elantra :: 2007 - After Oil Change Stuttering When Stopped / Wheezing When Gears Shifting?
I have a 2007 Manual drive Hyundai Elantra with 98,000 miles on it. Prior to going to Valvoline (who I know are not the best oil change places) if I was parked with foot on clutch and brake there was a tinny noise coming from the engine. I was going to have it checked out.
Fast forward I had my oil changed at Valvoline on Saturday (2 days ago) since then when parked with foot on clutch and brake the car begins to make a stuttering/shuttering noise and is shaking a bit (in time). In addition when I shift gears and go faster there is a wheezing noise.
I assume I need to bring this back to Valvoline? Is there anything that they could have done during the oil change that would cause this issue?I didn't get the air filter but it wasn't that horrible. They of course said I should get the radiator flush and the transmission flush.
Lexus GS 2006-11 :: 2010 - Rumbling Noise When Accelerate From Dead Stop With Wide Open Throttle
So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.
I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.
Accent MC (2006-11) :: 2007 - Fluctuating Idle Stopped At A Stop Sign
Ok so I have I 2007 hyundai accent with a weird problem. When the car is in normal operating temperature (180-210) and stopped at a stoplight or stop sign the car will have a fluctuating idle. This problem only happens when the car is at idle and with the heat or air conditioning on. With the heat and the air condition off the car will do it once in a great while. Things I have done so far. Replace the pcv valve clean the egr. To me it sounds like a voltage problem like the car is having too much load at idle. But I am unsure. Took it to a mechanic the other day and he couldn't replicate the problem.

Huge problem. Everything was fine the first couple of times I drove today.
Tonight, when I was getting in the car, it turned on. I tried to change it from Park, but it just stuck and wouldn't move and let me change at all, even down to reverse. It's just stuck in park.
What is wrong with it? What's stuck, and what can I do to get it unstuck? Or else, I'd have to get it towed because it won't budge from park
Mazda - Tribute :: Car Starts But Have To Rev The Engine And Restart At Every Stop Sign And Red Light
My Mazda tribute 2003 (manual) has developed a habit of 'pretending' to be overheated. If I do more than 2 or 3 stops as I run Saturday errands on a warm day - the care refuses to start and' continue' to run. I can start the car but have to rev the engine and restart at every stop sign and red light- If I pop the hood and wait about 40 minutes the car seems to 'cool' down and will run. The engine does not redline - water and coolant are fine - Is this just a faulty thermostat or is it some insidious vapor lock....

View 9 RepliesSubaru - Forester :: 2002 - Loud Knocking Sort Of Sound At Startup - Engine Shuts Off At Stop Sign
I have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?

I'm trying to diagnose a stumbling condition in a Hyundai Elantra 2008 with 84,000 miles. Occasionally when driving between 25-40 MPH, the car will shudder/stumble - almost like the engine is trying to shut off. However, it keeps on driving after a few seconds.
I cleaned the throttle body - it was quite dirty - but the problem continues to occur.
I didn't see anything related on several searches.

View 2 RepliesElantra HD (2006-10) :: 2008 - Bad Gas Mileage And Skipping Gears
I have a 2008 Elantra with 50,000 miles. I know I was overdue on the tranny fluid change and the car was getting bad gas mileage and skipping gears. I brought it in and had the tranny flushed and refilled and now its running good. I thought it would be good to get a price on spark plugs because the book said replace at 60,000. I called the dealer and he basically told me he has not sold many of the plugs and they should last 100,000.
I seem to be getting conflicting info on what should and should not be done at the maintenance books written schedule. I looked for a price on Fuel Filter air filter which is in the maintenance to replace but again conflicting info stating that should not be changed unless there is a problem. Anyway, what should and should not be replaced at specified intervals? I know the tranny fluid change should have been done at 30,000 because it was very dirty and causing issues for me.
Elantra HD (2006-10) :: GLS Start Jerking As Gears Switched
I recently bought a 2010 Hyundai Elantra GLS with about 40k on it. It was driving perfectly fine for about a week until the car would start jerking as the gears switched (I should note I switched the car out of ECO mode when I got it because I found it harder to accelerate with it on. The ECO mode keeps the transmission in higher gears to support fuel economy). I went to my shop and had the transmission fluid flushed and replaced. The car switches gears a lot better now, but another problem seemed to arise. About a mile or so after turning the car on and driving, it will switch into neutral for 3-5 seconds until I hit the gas hard enough for it to catch on and move. I've had multiple experienced people drive it around for awhile and they seem to find everything completely perfect with the car. Could it just be the way I drive, turning ECO mode off, or could something actually be wrong with the transmission or other parts?
