Toyota - Highlander :: 2002 - Hesitates Upon Acceleration At Low Speeds

I have a 2002 Toyota Highlander that sort of chokes. At random times while driving, the car hesitates on acceleration, chokes a little, and then continues to accelerate. It is an automatic transmission but it feels like I can feel the shift in gears. usually happens at low speeds (20 mph). no matter time of day or warm up period. I have been having regular maintenance at dealer. there was a caution note that I would need spark plugs replaced... is this it? a result o f needing new spark plugs? or something else?

Corolla :: 2001 Toyota VE Hesitates To Pickup After Long Idle Time

Mine is toyota corolla - 2001 VE model. It has 116K miles in it.

It hesitates nowadays to pickup after a long idle time, say in morning when i start to work or when i leave from work to home(idle time of 8 to 10 hrs). I noticed this problem only during very high temp, say atleast 80F.

Hesitation will be there for 4 or 5 secs and will not move even if i give full acceleration, but after that it moves normally.

Car has automatic transmission and i only see this i put it to Drive(D or D2) and not when i do reverse.

Toyota - Corolla :: 2009 - Lack Of Acceleration Sometimes While Driving

I have a 2009 Toyota Corolla with under 90,000 mi. Sometimes while driving, the car will refuse to accelerate and slow down to about 10 mi an hour. The only way to fix it, is to pull over and turn the car off and restart it. It immediately responds and it doesn't happen again. This lack of acceleration usually occurs in the first 5 mi of driving. I have a new battery...

Toyota - Corolla :: 2001 - Periodic Hesitant To Non-existent Acceleration

The car had been idling a little rough lately and I'd noticed a drop in MPG. After trying a few easy fixes I finally replaced the O2 sensor a few weeks ago. The idle has leveled out but ever since then I've been getting periodic hesitant-to-non-existent acceleration. Sometimes it works just fine (better than it's been in years, actually) but then sometime it will take forever to accelerate from a stop.

I'll give it some gas and it will just roll forward at barely more than an idle for half-a-block until something kicks in and it levels out around 30mph. This doesn't happen consistently though and I can't see much of a pattern in when it happens or why. It seems to work a little if I ease into the gas very gently, and it is worse when I try to gun it. I was worried it might be the fuel injectors or the ignition coils.

Toyota - Corolla :: 2004 - When Shifting Into 2nd And 3rd Gears Over-Throttle During Acceleration

Every so often, my manual transmission Corolla will "overthrottle" during acceleration, especially shifting into 2nd and 3rd gears (and sometimes even 4th), i.e., the engine will race above the usual RPMs associated with each gear, just for a bit. This however, isn't consistent. I still need to check if the engine air filter is dirty, which I suspect could be a part of the issue.

The vehicle has ca. 124,975mi, and only started exhibiting this problem 2-3 months ago, and only in 2nd gear. Again, this issue is very intermittent, and sometimes I can go a week or two without any incidents at all. The regular maintenance (oil changes, cooling system maintenance, etc.) has been faithfully performed according the manufacturer's specifications.

Corolla / Matrix 2009-13 :: Toyota VVTI 1.8 GLI - Acceleration Delay While Shifting

I currently own a Toyota Corolla VVTI 1.8 2009 GLI. I have been racing this car here at our auto drome for over a year. Last race it starting giving me real bad issues with shifting on the track. I can be a 5,900 RPM and shift to a higher gear and the car will choke and drown and it takes forever to recognize I'm accelerating. I know this is because of the computer and the electronic accelerator it comes with ( I can't remember it's name in English). My gas pedal is Denso and I understand there is an adaption that can be done to the cable to trick the computer.

Toyota - Corolla :: 2004 - Stalling / Running Rough And Hesitate On Acceleration

I'm having issues with my 2004 Toyota Corolla with 118K. Every few weeks, the car will go through a phase where it will stall out, run rough and hesitate on acceleration. Oftentimes it is accompanied with the rotten egg smell coming from the catalytic converter. When I decelerate to a stop light, the car will stall. When I start it back up, I have to rev the engine to 2000 rpm in neutral to keep it from re-stalling. Once I get up to about 10-15 mph, the car will jerk and sputter, and at 40mph, the jerking motion gets worse. If the car doesn't stall it'll run rough and have the rotten egg smell. I'm assuming the smell is from unburnt gas.

I find it happens more often when I don't let the car warm up for a few minutes. I've taken it to my mechanic, and i've gone through 2 MAF sensors, cleaned the throttle body. I changed the iridium plugs at 102K and am on top of maintenance with filters, oil and such. Of course when I bring it to the mechanic, the problems don't show up, and we are kinda blind to what could be causing the issue. Also, if I park it for a day or two after the issue occurs, the problems go away. What to look for?

Toyota - Corolla :: 2001 - Loud Spark Knock / Engine Pinging Noise Under Acceleration

My 2001 Corolla w/80k developing a considerably loud spark knock/engine pinging noise under acceleration. It throws no codes but pings like crazy and it never used to. It's happened gradual over a long period of time. I've cleaned the throttle body and have done all regular tune up items with no improvement. It doesn't ping at all on 93 octane, does some on 89 and terribly so on 87. Why is this? Does the 93 octane just act a a richer mixture of fuel to alleviate the ping? Should this sign point me in the direction that it's definately a lean issue causing the pinging?

Toyota - Corolla :: 2002 - Engine Noise On Acceleration - A/C High Pitch Noise

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.

Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?

Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?

Camry :: 2005 Hesitates On Acceleration

I just bought an 05 Camry with 40k miles. Runs great. Decided I'd have a tranny flush and coolant flush done. Oil was done recently. A couple hundred miles later and today I've got a noticeable hesitation when accelerating. It's not a herky jerky stutter, but a smooth, consistent like a loss of power like I'm quickly letting my foot off and back on the accelerator. Doesn't seem to do it when not in gear, just under acceleration. Checked trsnny fluid and it's ok and full.

Grand AM :: 1997 Hesitates / Bogs Down On Acceleration

I have a 97 Pontiac Grand Am w 3.1 engine that is my son's college car. We recently rebuilt the original engine and put it in after having a 99 monte carlo 3.1 engine in it's place and it had a head gasket problem as well. Just before we switched engines my son was noticing that it would kind of hesitate under acceleration from about 1500 rpm to around 2000 rpm especially when it was wanting to up shift. I figured it would resolve itself with the engine change. It did not. It has now gradually gotten worse.

My son drove it to Liberal about 4 hours away and he stated it was worse and especially when you would get into overdrive it would drop down to around 2000 rpm then start sputtering or loading up or just being dead then would down shift to 3rd and try to clean itself out and speed up and then up shift to OD and do the same cycle again. I drove it back and kept it in 3rd gear and seemed to run fine at 2500 or higher. I also had to go thru low, and 2 and feather it up from a standing start. It idles fine as well.

I thought it might be like one of the saturns I had which ended up having a plugged Catalytic converter and a bad coolant temp sensor. This morning I did a test hole and it made no difference. I tried a different coil pack/ESC and it made no difference. I cleaned the MAF sensor and no change. The fuel pressure is 41 then 38 when idling then 43 when remove the fuel pressure regulator vacuum hose. I also changed the fuel filter.

I was kind of ruling out the tps, iac, and egr and water temp sensor as those were part of the other engine when I put the other engine in so they are different and I am assuming they must be good. Plugs and plug wires are new as well. It has not thrown any codes. I did notice that when it is just in park and you press on the accelerator to rev it up it only will rev to 3500 rpm and will shut down like a rev limiter is kicking in and just do a kind of surge thing. My saturn did that too and it was a plugged cat and when I knocked the biskit out of the manifold on that car it stopped. I have already got that ruled out though.

Elantra XD (2001-06) :: Hyundai Hesitates On Acceleration

I love my 01 Elantra great gas mileage and it just zips around with no problems. Recently had an issue where i was depressing the gas pedal but it just decelerated and never was able to get above about 20mph. I pulled over, tapped on a few parts in the engine and restarted the car... the problem went away. It has some hesitaion when I accelerate. The check engine does not come on ever not even when I start the car . . . What the problem might be ? MAF, modules, ECM.... ?

Bmw - 650i :: 2006 - Hesitates / Loses Power Under Acceleration

My 2006 650i loses power under moderate to heavy acceleration. If I accelerate from anywhere over 2500rpm, it will accelerate then the engine rpm will drop suddenly by 500-1500rpm, and then will continue to accelerate again from this lower rpm. It only seems to happen once each time I punch the pedal. The car does not throw any codes. I have had the dealer and Dinan Performance examine the problem and they have not been able to isolate the problem. They have run vacuum leakage tests, fuel pressure tests, and may have checked the throttle position sensor. This really takes the fun out of driving this car. I have about 50K miles on it.

Elantra MD (2010-15) :: Wavy Acceleration Feel And Sometimes Hesitates A Bit

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 sparkplug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gapped under .022 but the manual called for .028. Everyone gapped to .035 with great results. Not checked the sparkplugs yet?

Ford Ranger / B-Series :: 1994 - Hesitates Under Acceleration

Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.

So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?

Honda - Accord :: 2006 V6 Hesitates During Acceleration After 5 - 10 Minutes Of Driving

I have a 2003 Honda Accord V6 that has some acceleration hesitation and general jerkiness, usually noticeable when the car has been sitting for a long period of time (overnight). The symptoms seem to dissipate after 5 - 10 minutes of driving.

When I begin accelerating, the car feels like it hesitates when shifting from 1st to 2nd gear. If I let off the gas a bit, then the car jerks a bit.

I'm sure it's not the transmission, because the dealer said the fluid and everything looks fine. Additionally, I have another Accord (2000) that does have a failing transmission and the symptoms on that one are very different from this 2003.

A couple of months ago, I was getting a CEL and had a friend of mine read the code with his OBD tool. It indicated that Bank 1 Sensor 1 was bad. I replaced it with a Denso. I think the problem got better at that point, but has "worsened" again over the past month or so.

Any clues what this might be? Things I can try? Ways to narrow down the issue?

Ford F-150 (2004-2008) :: Hesitates And Dies On Light Acceleration And Shifting

My son in law's 2004 F150 had been having a random hesitation and dieing on light acceleration. Now it is every time he drives it.Here is the scenario. After taking off from a stop, with light acceleration, when speed reaches 22 mph in drive, it is like you turn the key off,,,except all the gauges still work,radio air all electrical seems to stay on,BUT the indication lights on the dash and the small red anti theft dash light for the security function comes on. If you try to continue accelerating, the truck will die, but if you let off on the gas and then continue to accelerate all is well.

I tried starting off in 2nd thinking it is a transmission problem same scenario except truck did get up to 29mph before experiencing the dieing issue. Tried starting off with Overdrive disengaged, same problem. The truck is throwing no DTC codes and Ford says unless it throws a code, they can't work on it. Truck runs great at highway speeds . My son in law says that if the truck does die,(by trying to force acceleration) he has to stop, and put the truck in neutral or park, and then it will restart. I have checked all connections at the transmission, rear end and all sensors/controls, but no solution. We are getting desperate and don' t know what else to check. It has the 5.4 engine.
