Lexus IS 2014+ :: Car Is A Bit Rough When Engine Is Cold

The tranny is a bit rough when the engine is cold. I understand cars run differently when they are cold (I'm not disputing that) but my prev 2IS' tranny use to be much smoother when running cold. I took my car to a dealer, made them keep it overnight and test when cold. They said the car is operating normal and the master tech didn't notice anything out of the norm. The car is jerky on the daily so it's not an isolated incident.

Lexus IS 2014+ :: Slightly Rough Idle On Cold Starts

Owner of a 2014 350 fsport here.... 15,000 miles ... I noticed on cold starts a slightly rough idle since its gotten colder here recently. After starting the car it'll start fine and everything but then as its warming up the needle sometimes jumps 75-100 rpm. its like someone tapped their foot on the accelerator and let off. no lights or anything and the car runs fine.

Heres the catch... i have a joe z catback and joe z intake with fsport filter, could this possibly be why? because of the airflow ? i also have been using Lucas fuel injector cleaner and lubricant.

Also when i put the car in park after driving, i notice the needle isn't steady, it does move a little maybe 20-50rpm, not sure if this is normal or not because i never really paid attention until now.

Ford F-150 - 1997-2003 :: Rough Shifting In Cold Weather

I have a 1999 Ford F-150 XLT, with the 5.4 and a 4spd auto. 172,XXX miles on the clock and i have owned it starting on April of 2014.

Tonight driving home from work, it took some time on the highway (4 miles) to shift into top gear. When you lift off the gas pedal after reaching the speed limit, normally the truck will shift from 3rd to 4th no problem. When I let off the pedal, there was no gear change.

It took sometime for it to shift up. When downshifting on the exit ramp, there was nothing abnormal. Where I live it is 19 Degrees Fahrenheit and this is the beginning of the cold snap that will last well into mid-January of next year.

Elantra MD (2010-15) :: 2013 - Transmission Failure / Shifting Very Rough Through Most Of Gears

Well something I never thought would happen with only 14,313 babied miles on my 2013 silver Elantra. I was driving home from my mothers house and I thought I hit a pothole, next I stopped at a stop sign took off and it started shifting very rough through most of the gears. I drove it around for 30 minutes and it was pretty bad. I decided to get it towed, I don't feel like breaking down in it.

Ford F-150 (2009-2014) :: Rough Shifting 2nd To 3rd Gear

For the last few months my truck shifts rough between 2e and 3e gear. However it only does this first thing in the morning, when I leave the house I speed up until the end of the street, then when I let go of the gas it'll rev up a bit and shift from 2e to 3e while making a big clunking noise which I can definitely feel ...

It does it sometimes very rough and sometimes just a little bit. I used to not worry about it but i'm starting to wonder if something is wrong with my trans. Could it have something to do with the slip yoke?

Ford F-150 (2009-2014) :: 2013 FX4 Shifting Into 4wd At Full Throttle On Its Own

I recently purchased a '13 FX4, i love the truck, the Ecoboost power is incrediable. Recently while passing someone it made a horrible grinding sound, the dealer advised that it was known turbo issue that should have been corrected before we took delivery of the truck. When we took it in the dealer called and said they have Ford corporate involed because when the truck reaches WFO the four wheel drive tries to engage. Said it might be soem sort of vacuum issue.

Specs : 2013 Ecoboost Screw FX4 short bed. No mods, 6500 miles.

Ford F-150 (2009-2014) :: 2013 - Transmission Not Shifting Properly?

I have a 2013 F-150 Lariat 5.0 L, 6 speed auto transmission crew cab truck with 44,000 miles on it. Recently I have experienced problems with the transmission not shifting properly. Three times when I have started out of my driveway, it has shifted into 2nd gear while I am going only 2-3 mph up my driveway which is about a 10-12 degree incline. It stays in 2nd gear even if I stop. When I pull out onto the highway, it shifted normally into the remaining gears. Then, the other night as I was returning home, while traveling up the road, it shifted into 5th gear and stayed there even when it needed to downshift. A wrench i-con appeared on my screen, my odometer showed dash lines instead of mileage and my seatbelt i-con appeared. When I got home, I shut the truck off and restarted it and everything was normal again. I have driven the truck a couple more times with no issues. The transmission shifts normally. Could a sensor be going bad ?

Ford F-150 (2009-2014) :: 2013 FX4 - Transmission Shudder When Shifting Gears

My son has a 2013 Fx4 crew cab 4X4 ecoboost with 8500 miles. He says in the morning for the first couple of miles while accelerating gradually the trucks shudders when shifting gears. After a few miles it goes away. Dealer says they can't do anything endless he can duplicate the condition. He went out of town for a few days and left me the truck so I'll drive it in the morning and see what it does.

Ford F-150 (2009-2014) :: 2013 - At Startup Idle Rough?

2013 3.5 Ecoboost. Starting the truck first thing in the morning, it idles very rough for about 30 seconds and then smoothes out. If I drop it into gear it stays rough as I back out of the driveway. Once underway it runs fine and otherwise runs/idles very smooth for the rest of the day. Doesn't appear to have any other symptoms of spark plugs/boots misfire so I'm thinking it might be something else?

On my old 02 F150 with the 5.4 this usually happened when the Idle air control (IAC) would get plugged up with carbon. I'd clean it and the idle would smooth out. This truck doesn't appear to have one.

Spark plugs are on my list for the near future. 47k on the truck so they are almost geting due. Trying to get my superduty sold before I spend a lot of time on this truck.

Ford F-150 (2009-2014) :: 2013 5.0 - Idling Rough On Start Up?

I've only had my '13 STX with the 5.0 for a little over a month now, but it seems like the past few days, something's caught my attention. As soon as I start my truck when cold, the idling engine seems to have more vibration than normal, which is to say I can notice a distinct vibration in the cab. It only does this for about 10-15 seconds, and then the vibration goes away when it idles down. The truck still runs and drives fine, and I only notice this when I start the truck without it already being warmed up. I don't recall noticing this the first few weeks I owned the truck, but I also wonder if I'm over-analyzing matters as well.

Lexus IS 2014+ :: Release Gas Pedal Or Not While Shifting

What's the best way to be faster when you shifting using pedal shift or stick shift on automatic transmission? Release the gas pedal before shifting and then hit the gas pedal again (just like driving manual), or keep flooring the gas pedal while shifting?

Lexus GS 2006-11 :: Transmission Shifting Rough And Seems Delayed - P0761 And P0781

My transmission has been shifting rough and seems "delayed" in shift response.

I can only go from gears 1-3 without revving up to 3500-4500 RPM's before it will go ino 4th.

It does not hold RPM in 4, 5, or 6 and instead goes down to the normal idle spot.

I had it diagnosed and the codes are

P0761 Shift solenoid C Performance or stuck off

P0781

1-2 shift error

Lexus ES 2013+ :: Transmission Shifting And Frequency - Car Won't Change Gears Quickly

I am coming from a 2001 Acura CL-S which is a 5 speed automatic, and that car wouldnt' change gears that quickly. I understand cars today change gears frequently to be in the best gear for fuel efficiency?

But I feel like my ES350 changes gears so much, even at the slightest speed change. Is this normal -perhaps it's because I haven't driven a new car since my 2001, 12 years ago! Even the slightest press on the pedal will downshift the car and into the lower gear, even on ECO setting. On my Acura, pressing lightly on the accel pedal didn't result in a lower gear, as I know the engine had more than enough torque.

I also love reliability, and this makes me think the transmission would have a shorter life span with all the shifting. I still haven't asked my dealer about how often to do tranny fluid changes (which I know is a different thread altogether about discussions about "lifetime" fluid).

Lexus RX 2010-15 :: 2013 - Loud Noise While Shifting From Reverse To Drive

I recently leased a 2013 RX 350 and started hearing a weird loud noise almost in the first week itself. It seems to happen whenever I shift the gears from Reverse to Drive. The loud noise comes from the back of the car and anyone sitting in the car (speakers turned off) can hear/feel it. It seems to be worse in the morning (or when the engine is cold).

I took it to the lexus service center and the person told me something about differential pressure, which I really didn't understand:-). However, he said nothing can be done and its not a safety issue and sent me back home without any fix. I have driven many cars in my life so far and never ever came across something like this. Is it something normal at all?

Santa Fe (DM - 2013+) :: 2014 - Air Conditioning Cold While Moving / Warm When Idling

I have a 2014 Hyundai SFS 2.4L with about 50,000 miles and love it so far. However, I have a concern, when I am driving on the highway or even back roads the air conditioning cranks real cold. However, when idling at a light there's an obvious temperature difference that is warmer. I have ECO "off" because when ECO was on it completely shut off the air when accelerating or idling. Is this a scroll compressor? The reason I ask is my FORD had a scroll compressor and exhibited the same symptoms and it turned out it was a $35 faulty valve, but convincing numerous shops it was, was the problem. Also, could it be low Freon? If so, does it take R-134A and is it something I can do myself?

Ford F-150 (2009-2014) :: 2013 - Idle Was A Bit Jumpy Warm Or Cold

Got a 13 f150 with the 5.0. I bought it used with about 14 thous kms, now it has 17. Ever since I owned it I noticed the idle was a bit jumpy warm or cold. I didn't really pay any attention to it as it wasnt throwing a CEL or anything but now that I have a roush exhaust and intake I have started to notice it a lot more....not that its worse but at idle my truck sounds like a boat. Weird comparison I know. It seems like it'll jump within +/- 200 rpm @ idle which IIRC is 1K rpm.

Ford F-150 (2009-2014) :: 2013 Ecoboost Sounds Like A Diesel On Cold Start

I've got a 2013 ecoboost with 31,000 mile on it. Generally it's been good but at 30,000 mile it started sounding like a diesel on cold starts. Usually after sitting overnight the first start rattles like a 6.0 liter diesel for about 3-8 seconds then it's quiet. It won't do it again all day usually. The dealer says there's no codes so everything it all good. It never did this until I hit 30,000 miles.

Lexus ES 2007-12 :: 2009 ES350 - Shifting From High Gear To Down Is Abrupt When Cold

This is the not about the plagued 2007/2008 ES350 with the tranmission issue. This is more of a generic issue. My car is a 2009 Lexus ES350 Premium line and was bought as a CPO from a Lexus dealership in Feb 2013. Currently mileage is ~98k KM

Issue: From a cold start and driving the car coming to a complete stop, I've noticed that the shifting from higher gear (2 or 3) down to the first gear at around 15-20 km/h is very abrupt. This is a little bit noticeable during the warm summer months and more pronounced during the winter cold months.

Changes: 1) Flushed transmission fluid last summer at Lexus dealership when the car was at ~78k KM, the issue is still present in the summer but a little less obvious.

What I know about the car is that:Cold start of car, the engine's RPM runs higher until car switches from open to closed loop operation (or was it from close to open loop?) When engine runs at higher RPM, car would want to lunge forward a bit. This is normal and expected. Anyway to assist the engine warm-up faster? (Coolant change? Thermostat change?)

Once the car starts to warms-up (i.e. thermostat shows at about 1/4 of the entire gauge range). This is no longer an issue. When car is fully warmed-up the gauge is at about 1/2 marking as a reference point. So when car is starting to warm-up, is the transmission fluid warming up faster than the engine due to the shifting? Or is the fluid warming up due to the warmth from the engine bay?

Desired Final Results: We all know that Lexus are well known for a smooth and comfortable ride. And from a cold start, the shift characteristics isn't smooth. What can be done to solve this issue?

Ford F-150 (2009-2014) :: 2013 - AC Fluctuates From Cold To Warm With Heavy Damp Smell

AC used for the first time since purchasing the truck last Oct. I notice and passengers in truck with me as well notice that the AC is not strong at all and it fluctuates from cold to warm with a heavy damp smell almost like its letting fresh air in mixing with the cold AC. It seems to be doing this more so when driving but will also do it at at idle after driving. Of course dealership states perfect temp blowing @34 and Freon at perfect levels. Max AC will not blow you out of the truck and reg ac at lowest setting feels like its on a vent setting. When AC first comes out it smells very damp mildew smell. 2013 F-150 Limited 3.5.....
