Infiniti - G35 :: 2003 Slows Down While Accelerating

My G35 has around 115,000 miles and it slows down when driving, particularly when driving uphill. RPMs reach 2-3 and car begins to drag with an occasional jerking. I've replaced all spark plugs (don't think I've ever replaced them since I bought the car used with 40,000 miles) and I notice one of the coil packs and its spark plug was oily, but then I also notice it was not connecting to the spark plug like the rest the rubber tip was ripped. I replaced the coil pack, but the issue still exist. I just got back from a test drive and this time it doesn't lose speed so much, but still trembles, especially when going uphill.

Sonata I45 (YF - 2011+) :: HIDs Pulsing While Accelerating

I noticed going up hill when the RPM's hit around 2100 RPM this morning it looked like my HID's went into a strobe type pulse. They stayed on but got brighter every partial second. Even from a stop if I accelerated with more than 2k RPM the lights flickered.

It's done it for two days, which happened to be in the single digits tempature wise. Do you think it's my alternator or my battery having the issues? Car is a 2012 so I'm leaning more toward battery load issues.

Sonata I45 (YF - 2011+) :: Excessive Engine Noise In Cabin Especially When Accelerating From A Very Low Speed

I recently acquired a 2014 Sonata Limited 2.4L. Don't know if its me or not but engine noise seems to be excessive in the cabin especially when I am accelerating from a very low speed, almost like something in the engine is loose. Had it at the dealership today for warranty work (seat belt) and recall work and asked the techs to take a listen when the do their inspection. They came back and said that the noise is coming from the electric fuel pump and that it is totally normal. Previous car I had was a 2011 Honda Accord Ex and it seamed quieter.

Sonata NF (2006-10) :: Lights Dimming When Car Slows Down Past 1500 RPM

My 2006 Sonata GLS headlights dim along with the entire lighting electrical system when my car slows down past 1500 RPM. Why??? I had the car worked on 2 weeks after i got it because of this and they replaced a timing chain thinking this was the problem, but it wasn't.

Sonata I45 (YF - 2011+) :: 2011 - Engine Code P0106

I just replaced my OEM battery with a duralast from autozone. The battery had 138,000 miles. Shortly after, the check engine light came on and code says P0106. Map Sensor. Seems like to much of coincidence that this happened. Have read that disconnecting battery cables for 3 hours may do the trick.

Sonata NF (2006-10) :: Low RPM When Not Accelerating

I am using hyundai sonata 2006 model (2.0). I just change my engine and the RPM of the engine I bought always drop below1000 when am not accelerating or when I apply brake and slow down in traffic. When the rpm is bellow 1000 my oil indicator light is always on and if my Ac is on it will switch off the engine. How I can increase the rpm to 1000 or a little above 1000 when am not accelerating (in idle position when the engine is steaming).

Golf/GTI VI :: 2011 - Whining Noise When Accelerating

Just recently I've noticed my car making a whining noise. I have a 2011w/ DSG, Stage 2 APR w/ DP and K&N Filter. I've researched some cases of the whine coming from intake but using just the K&N I doubt it's that. Plus the noise just started recently and the filter was put on 4k ago. I read somewhere that it's a leak in the exhaust??? What it could be?

Sonata NF (2006-10) :: Jerking When Accelerating Until The Car Warms Up

This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

Sonata NF (2006-10) :: Rattling Noise While Accelerating

Over the last couple of days, my 2009 Sonata V6 has developed what I best can describe as a rattling noise near the engine when I am accelerating the vehicle (noise changes based on throttle input). I only hear the noise with the car in drive, if I shift into Neutral or when I am in Park I don't hear the noise when I rev the engine.

Sonata NF (2006-10) :: Pinging Noise While Accelerating Around 60 Mph

Today I noticed a pinging noise on the highway when accelerating around 60 mph. It certainly doesn't sound like its coming from the lower end and it happened with the engine fully warmed up. I've always changed the oil on time, never has it overheated and it performs very well otherwise, no power losses.

No check engine light is on. In fact, I have heard this same noise on older cars I have owned (Cutlass Ciera) around the same mileage 105000. I am thinking of adding an oil additive, and I have heard that 1 Qt of ATF fluid followed by a drain and refill works well.

I might also do a fuel system purge, BG's has a good machine for that Could this be an EGR issue? Replacing EGR valve? If so was it easy and where is it located. I am hoping I didn't break a valve spring....

Camry :: 2011 SE - Bad Smell From Vents When Accelerating Hard

So I've been noticing this for a while, pretty much ever since ive had my car. I have a 2011 camry se v6 and when i go hard on the gas from a dead stop or accelerating on a on ramp on to the freeway i get this smell coming from the vents that smell like rotten eggs or something and my friend in the back said he can smell it too. This only happens when i accelerate really fast and shoot up to or over 4500-5000 rpm, why? i use cheveron 89 gas which is plus.

Elantra MD (2010-15) :: 2011 GLS - Rattle Coming From Under The Car When Accelerating

Currently have 85k miles. About 20k miles ago I noticed when I have the driver window down I would hear a rattle coming from under the car when accelerating. Doesn't happen every time but does quite often. Usually goes away almost immediately. I'm not having any other issues and with my warranty out I'm not anxious for a drip to the dealer.

Sonata NF (2006-10) :: Noise While Driving And Accelerating Hard

Tonight while driving and accelerating fairly hard we began to hear a noise. The car sat parked for roughly 5 hours and then we began to drive it home (apx. 12-15 miles). About halfway through the drive the power steering went out and the battery light came on. The battery light would turn off and the drivers seatbelt light would come on even while it was buckled. These two lights alternated being on and off 2 times each. We heard something that sounded like a rock got kicked up into a wheel well. After getting the car home with no power steering we noticed the car had begun to run very hot. almost all the way up the gauge.

Sonata I45 (LF 2015+) :: Engine Shudder At 108km/h Upon Accelerating

Well, my MIL came on, and hasn't left (yes, my gas cap was tightened). My bigger concern is that when I'm on the highway, if I have to slow down for traffic, upon accelerating again, when I hit 108km/h, the car does a crazy death shudder, and slows down...I have to release the pedal, let it slow to around 95, and then I can accelerate again. I'm gunna wait and see if the light goes off after a couple of days, but this is worrying.

Camry :: 2011 Toyota Transmission Loud Whine When Accelerating

I just purchased a 2011 Toyota Camry with about 36,000 miles on it. Within the past couple weeks, the transmission began producing a very loud and uncomfortable whine when accelerating at low rpms. The sound resembles that of a kazoo or a super charger. I've taken the car to several dealers and have been told that it's a "normal" noise for the 2011 Camry. To test the validity of this comment, I asked to test drive a few other 2011 Camry's and only a couple made this same noise. The dealer did replace the power steering pump, as he thought that might be causing the noise. However, the noise is still present and seems to get louder with each day I drive the car. I do not believe this noise is normal.

Ford F-150 (2009-2014) :: 2011 - Swoosh Noise After Accelerating?

I have a 4x4 2011 5.0 f150 with 65k miles. Bought it 4 months ago. I have noticed it makes a swoosh or air sucking noise for a couple of seconds after acceleration and will do it while driving. It is not constant but comes and goes. I have not checked codes. Other than that, really like the truck.

Ford F-150 (2009-2014) :: 2011 - Sluggish And Bucking While Accelerating

I bought a 2011 Ecoboost F150 last week. I test drove the crap out of it, and was pleased with it. Go figure, get it home and within a few days, when I put a little foot into it to respond to a call (vol. firefighter) it does the crazy buck me around bit. I do some looking around here and get a little paranoid about the water ingestion thing. It did throw make the CEL flash for 30 secs or so. Then I dig some more and see these things eat spark plugs. I am sitting at 86k miles on it, so I figure, let's try the simple first.

I go pick up some Motocraft plugs and within two mediocre innings of listening to the Angels play, I am finished. I take it out for a test drive, and oh my goodness... the difference. I couldn't get it to buck around or anything. I got on the highway and really got on it, to test and see... no problems whatsoever. Checking the gap on the plugs that came off, they were all between .045 and .050. Moral of my first post.... don't underestimate the importance of the basic maintenance items.
