My car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or spark plug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gaped under .022 but the manual called for .028. Everyone gaped to .035 with great results. Checking the spark plugs?

View 12 RepliesLoving our new SF, but have noticed a problem periodically when starting out from a dead stop. When the accelerator is pushed, sometimes there is a hesitation in the engine. Almost feels like the gas has been restricted for a second, then it engages and goes. I've notified the dealer and plan to have them look into it at my first oil change, but it is happening more frequently and think it may be something I need to get looked at sooner than later.
View 61 RepliesMy 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 RepliesI am going to be looking into this a little bit tomorrow with an oil change and noisy hub bearing.
Car : 2002 Jetta GLS 1.8t stock 5spd ~165k miles
Symptoms : Light acceleration (day to day), After shifting into 2nd gear, the rpms come down to 2-2500 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.
Moderate acceleration (casual hwy on ramp, stoplight fun), After shifting into 2nd gear, the rpms come down to the 25-2800 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.
Hard acceleration (short hwy on ramp), After shifting into 2nd gear, the rpms come down to the 28-3100 range. I do not feel any symptoms noted above.
The hesitation felt is enough to cause the car to feel like it had a short loss of power. This does give a jerky feel.
My thoughts : I know there were issues with the coils in this model/year. I have verified through the deal that the vin had received the replacements but unsure if they are the actual replacements. My dad thinks it may be turbo related (which is also stock and never pulled apart to my knowledge).
I found that this KO3s turbo should be fully spooled about 2200rpms. It seems to coincide with my lower rpm accel that maybe I am loosing some of the spool and feeling that?
Other Info : Am I way off or is there anything I can check for easily? I am not very knowledgeable in turbos beyond their basic functions. This is also my first turbo car. I have owned the car 2yrs now. It seemed to have always been there but I don't recall noticing it on the initial test drive. The trans has been replaced since noticing this for other reasons but did not correct this.
The sound is only there when the engine is under any load. If I am very careful I can raise through the RPM without the noise, but give it a little bit more gas and there it is. It sounds kind of like an exhaust leak, but I'm not sure.

Listen closely right at 0:12-0:15. That is me accelerating for 3 seconds, and that sound like a rain stick is my engine.
2013 Elantra GT ...
I have a 2013 GT and my wife a 2011 sedan.
[URL] .....
I've looked it up and didn't find any reports of it happening to the GT. (I admit I didn't look too hard!)
It happened to my wife's 2011 sedan when accelerating onto the highway. Just as described in the "massive smoke" thread. I couldn't see the car following behind me, the smoke was that bad. No exaggerating!
-- no check engine light
-- no change in temp
-- car drove fine immediately afterward (we babied it till we got home)
-- oil level and colour OK
-- coolant OK (overflow between lines)
-- next day car felt fine during full-throttle 80-120 km/h acceleration.
-- mentioned it at dealership, with service adviser, service manager and mechanic all listening to the story. They were stumped but offered to look at it. Adviser suggested a "BG Products fuel induction" treatment, which I'm assuming is bogus. (Haven't had a chance to check into it)
My web searching suggests the car had a "carbon blowout" cuz my wife rarely drives on the highway. I've heard of this but always thought it was just a myth. I mean, seriously, have you ever actually seen a car throw up a James Bond smokescreen just cuz it hadn't been driven hard? I'll betcha five bucks that if I took my mom's babied 1997 Camry onto the highway and floored it, nothing would happen. So what's up with the Elantra?
I have noticed that the throttle is a bit light...meaning that the resistance bringing the throttle back to idle is too soft. Two issues as a result. Unexpected..faster acceleration from a stop and my leg tires a bit in town keeping speeds in the 30-45 range. Assume there is no retro fit and/no adjustment. It's rather odd in that just about everything else on the vehicle seems well thought out and executed. I could complain about the over boosted power brakes....or the brake squeel that the dealer can't/will not fix...but the throttle is really getting on my nerves.
View 5 Replies2001, 5-speed, 6 cylinder, 140K miles. Under acceleration, it feels and sounds like I'm driving over road warning strips. While coasting, it goes away. The CVJ's and wheel bearings appear to be OK. Could it be the final drive? It happens in all the gears.
View 3 RepliesThis is the second time I notice a problem with my 2014 elantra base model. The car only has 13000kms and today the car acted with a weird behaviour. This car has a manual 6 speed transmission.
Out of the blue the car jerked like it had a problem with the transmission switching gears which is weird as this is a manual.
The second time this happened the wife was driving and she said that she was in is third gear and she pressed the clutch and the brake at the same time and she felt a small jerking feel in the clutch like it didn't engage.
The problem is that I cant reproduce the problem. The car is still under warranty and I don't want to go to the dealer with a problem that I cant exhibit.
My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.
I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".
Its a 2012 Elantra Limited, all stock everything, 53981 miles.
I have been getting this weird bumpy feeling when making left hand turns and even sometimes when going strait on the road. It does not seem to effect the breaking for acceleration of the car. This does not happen all the time and will start and stop without any change in driving.
View 22 RepliesIt'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....
View 3 RepliesI 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.
View 5 Replies04 Touareg V6 ... Slow acceleration.. running rough.. hesitation during acceleration especially when going up hill. Engine light is on. P0300 is the computer code coming up.
View 4 RepliesWhen I press on gas the engine hesitates as if it's going to stall and the acceleration takes effect only after 2 seconds or around there! The check engine light is also on.
View 13 RepliesHave 2014 XC-90 w/10k miles. Problem is sporadic (has happened approx 10-15 times over past year).
From standing stop (stop light, etc) -- press on accelerator and VERY LITTLE to no acceleration. Engine continues to run smoothly -- no indication of fuel starvation, no roughness --- just no acceleration. It does NOT appear to be transmission oriented because when it finally "kicks in" there is no feeling of transmission shifting or wild tach movement (to indicate that there was a changing of the gears, etc). I get things back to "normal" by pumping the accelerator (usually a reflex action because the are vehicles behind me wanting to "go"). VERY disconcerting issue.
Local Volvo dealer says "cannot find any error messages", etc. My only complaint with the car -- second XC-90 and 5th Volvo.
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?
View 1 RepliesJust purchased a 2014 Yukon XL it is has a bit of hesitation upon acceleration. Did not think much about initially but it is a bit bothersome. I have an 02 Suburban and never had that issue. I did also notice the same issue when test driving a 2014 Suburban.
View 1 RepliesI have a 04 santa fe 2.4L 4cyl. I recently did an engine swap, old motor threw a connecting rod. I put my intake, exhaust manifold and head on it. Timed it. All new gaskets. Turn the key and it fires right up and runs great. But when you accelerate it sounds loud (almost diesel like) and doesn't shift at the right time, also while trying to cruise it will drop about 300 rpms and then come back up, then back down and up every 3 to 5 seconds. The transmission was fine when the old motor came out. The head/intake were fine also. All the vacuum lines are connected, cant hear a vacuum leak anywhere. But it keeps throwing a throttle body sensor code and it wasn't broken when the old motor went, i even swapped another used one on it and it still throws that code. I am thinking it has to be intake related.
View 4 RepliesMy 2001 VW Passat 1.8T manual transmission is experiencing loss of power/hesitation during acceleration. Occasionally the check engine light will blink for about 10 seconds during this time. My valve cover gasket blew about 7 months ago. I had it replaced along with 2 ignition coils. Since then I have had replaced the other 2 coils and spark plugs because of this recurring problem. I have also replace the mass airflow sensor for the second time. The diagnostic check continually shows misfires in different cylinders for which I again tried replacing the coils. I have also received the codes for "fuel mixture too lean" as well as for too rich. What could be causing this?
