When driving if you ease off the accelerator at an intersection and go again the car hesitates badly and then slowly picks up it has had new plugs etc., very worried nearly got wiped out this morning...
View 1 RepliesI purchased a certified automatic 2013 Mini Cooper a week ago. After a total of 254 miles driven off the lot, the accelerator quit responding in the middle of an intersection. I was attempting to make a left turn. Only the accelerator quit functioning, everything else seemed ok. The engine didn't even rev when the pedal was pushed to the floor. I was pushed out of the intersection and shut off the car. When I restarted it the gas pedal was operational. No codes presented, and the dealership couldn't detect codes on their equipment. They sent the info to the MINI technical department (their engineering team) who said it was a software issue. The service rep who passed this on to me said that the Techs data showed there was an "error" which caused the failure, they could verify that using the data, and that a software update would be done to correct the problem. However, the MINI service department will only document on the paperwork that an update was done, they will not document the error in writing. Seem weird? I have serious doubts about this car in our brief history together.

In driveway with constant pressure on accelerator (stick wedged between pedal and seat) a static rpm can be maintained for only a short time(< 2 min) time before rpm drops rapidly to idle rpm. Accelerator pedal never moves (still depressed to high rpm position) but engine is just idling away.
Note: New fuel filter and fuel pump recently installed as engine intermittently chugged/hesitated (acted like out of fuel for a fraction of a sec) especially with warmer air temperatures. Still does this but now unable to maintain driving rpm for any length of time.
My 2001 hyundai elantra hesitates throughout 0-15 mph I have changed out TPS,MAP,& IAC and i have did a full tune up and a transmission flush & I still have the same problem.
The one thing i did notice is the engine doesn't rev up when ac is on. Idle stays the same with A/C on or off.. when I go to plug the IAC in, with the car running it opens the valve but once i fully connect the plug it closes ... does the same thing with new and old IAC..... and the connector on plug is good..
2001 elantra 167000 miles, started a hesitation when given gas and check engine light came on. After hesitation rpms go up it runs good. Code is # 2 cylinder misfire. I have changed plugs, ignition coil and ran seaform into vacuum line and tank. Still no change. Could that 1 injector be clogged.
View 2 Replies2002 elantra hesitates and sometimes stalls staring from rest. Worse when cold but still sluggish after warm up. Where do I start?
View 7 RepliesI am having a slight hesitation problem on my 2002 gls. When the car is cold and I am shifting with low rpm there is a slight hesitation untill higher rpms then it seems to clear. I wouldn't say a "stutter" or enough to "buck" the car but definitely noticeable. The strange thing is when the car gets up to temp it seems to stop. Almost like a carb on an older engine.
View 3 RepliesI just bought a used 2004 Elantra that has 97,000 miles on it. When I took the vehicle out for a test drive it was smooth and quite. That was on Monday its now Saturday less than 300 miles later and the check engine light came on and it is having serious hesitation issues?! I am going to take it back where I purchased it from on Monday when they open but in the meantime I would like to know if its could be something simple?
View 14 RepliesI have a 2001 Elantra with 126k miles. For months it's been randomly hesitating, meaning I'll be riding along and suddenly the gas pedal will do nothing...then about 3 seconds later, VROOOM, the gas pedal will start working again. Recently, it's started stalling as well.
I've already replaced the MAP sensor, input speed sensor, throttle position sensor, spark plugs, wires, and coil pack. Nothing has worked, but it is getting progressively worse (it stalls more frequently, and the gas pedal becomes suddenly unresponsive more often).
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.

Starts fine, loud motorboat like noise ... then car hesitates when put in any gear for a few seconds before moving ... then drives fine. Slight shutter at low speeds 30 and under....hit the expressway and its all good. Is that the fuel pump, a relay, what? It has a brand new radiator, gasket, thermostat and cover...so its not the cooling system.
Also...the check engine light is on, the pcm code says its only issue is the cat con...I don't think this issue is related cuz it was already on when the radiator killed in the middle of the highway....the noise is new. The hesitating isn't....that's been going on since before the check engine light came on....but its getting worse.
About once every 4-6 months or so, when I floor the accelerator, my Sonata behaves in a very odd way. Instead of the typical surge of acceleration, it actually hesitates/decelerates for a second or so, then kicks in like normal. This is so pronounced that I lunge forward in my seat a bit before it kicks in. I've not yet been in a situation were this behavior has endangered me but it is quite disconcerting when it does happen. Obviously this is not something that is repeatable in a manner for any shop to diagnose. There is no CEL and it occurs so infrequently that I'm not that concerned about it yet. The only consistency about this is that this occurs while driving around town after I've slowed down to around 5-10 MPH approaching a light, taken a right turn and then attempt to accelerate into traffic. Since I'm usually in a turn lane, I'm out of the way of traffic and can adjust to this situation without any issues to either myself or the traffic around me.

It stalled when backing up after being parked. Mechanic did diagnostic test and it showed zero...He changed 2 wires to spark plugs..Spark plugs have only 20,000 miles and SUV has 68,000 miles.
View 6 RepliesJust purchased my 2007 Passat 3.6 FWD and we just love it but having hesitation problem? This only happens from a stop, when you step on the accelerator it seems to have a delay of a second or two before the engine response.
View 12 RepliesI have a 1999 Toyota Camry (4-cylinder). When I step on the accelerator, it hesitates for a moment before accelerating. Once it finally does kick in, it isn't jerky but fairly smooth, just takes a while before it will go. Other times, when I accelerate, and the car is actually moving, I feel as though the RPMs are higher than they should be considering the (slow) speed that I'm going. These problems have increased quite a bit over the past few weeks.
Prior to this, my check engine light came on. An autozone employee checked the code related to the light and said I have a faulty EGR. He didn't seem to know whether or not this would be at all related to my acceleration problem. Someone else suggested that an EGR's importance is more environmental than functional. While I'm all for "being green"...can only afford one problem at a time, and the acceleration problem comes first.
If the two are connected, and if not, what my acceleration problem might be? How critical is a properly working EGR anyhow? The actual code according to autozone was EGR P0401...

Throttle seems to be sticking and causing engine to rev between shifts, and staying slightly on after I let off the gas
Engine continues to rev up uncontrollably for about 10 seconds after feathering the gas pedal (between shifts). If I floor the gas pedal and release it quickly, it closes the throttle and fixes the issue.
Thought it may be a sticky throttle body, sprayed a generous amount of Carb and Choke cleaner into throttle body...did NOT resolve the issue. Its a Drive by wire, so no throttle cable to blame or to clean.
Turns out, the accelerator pedal assembly it self, is not returning/springing back to "up" or closed position and is sticking during the first few degrees of travel. It is very dirty, and gold.
How to clean/lubricate this thing? Its plastic. Or should I just order the replacement? I hope the pedal isn't programmed to the car itself? shouldn't be...but you never know
On my daily commute in stop-and-go traffic, on a bridge, headed downhill, suddenly neither the accelerator nor the brake pedal would engage in my 2008 Elantra. Cars in front of me had sped up, then ground to a halt, and I was coasting downhill toward them, at a pace too fast for the handbrake to stop me. I couldn't downshift either (the car has automatic transmission, but shifting to low lets the engine slow you down). With nothing else to try, I shut off the ignition and then turned it on and, amazingly, all was back to normal. The dealer didn't find any trouble codes in the computer so they say the car must be OK to drive. But I don't feel safe driving the car. This might have happened and what I can do to fix it?
View 16 RepliesI've noticed when encountering a moderate hill at 60 mph in cruise the revs might suddenly increase from 2200 to 2700 rpm, then back down slowly as I crest the hill. If I'm in manual mode it stays in 6th gear, but almost feels like a downshift. I also feel no accelerator pedal movement. Is this a two stage intake at work?
View 3 RepliesWith Eco off my sport has a nice bog/hesitation when accelerating. Doesn't matter if ac is on or not. I'm also using shell from the same station I've always used for years. The 2.0 is still pretty new. My cruze turbo had the same kind of issue and turned out to be the spark plug gap was too small from the factory.
View 1 RepliesWhen attempting to back slowly the T2 revs the engine to about 1700 and tries to over power my brake. My foot is on the brake not the gas at all. The harder you hold the brake the more the T2 tries to over power it. It cause the truck to lunge when you ease off the brake. The is amplified by any pitch to what you backing up. Any slope makes it worse.
View 2 RepliesI have a 1999 Hyundai Accent manual transmission. It's been a great car but over the past few months there is a problem that the mechanics can't figure out. The car is fine driving initially. Once it's warmed up, parked for about an hour, and started up again, it bucks every time I ease up on the gas. It seems to be worse at slow speeds - 30 or under - but still occurs at higher speeds.
