Camry :: 2004 Hesitating - No Pedal Response In Cold Weather

I have a 2004 2.4 liter camry .

When I first started the car it hesitated a bit but,it was very cold. I went to give it a shot of gas but had no pedal response . I shut the car off gave the gas pedal a few whacks and it worked fine .

On the way home the car worked fine for about 30 km , just before I got home the pedal had no response again, shut the car off , started it and drove home .

The next day it was worse , so I put it on a scanner ,the scans said bad throttle position sensor (tps) and also a few codes for throttle body valve sticking or bad signal .

I tried the easy fix first and changed the gas pedal with sensor , same thing , then I changed the throttle body itself , same thing, then went a installed a computer (ecu) and that won't even start the car .

My ecu 89661-06a0, replaced it with 89661-06a2.

The car will start on all 4 cyl and idle high for a few sec then drop like normal , once the idle hits 8k rpm the car is only fires on 2 cylinders 2 and 3 , (changed then swapped coils no difference) as its idling on 2 cylinders and I press the gas pedal it will rev to about 2k rpm and run on all 4.

Isuzu :: Hesitating While Accelerating

I replaced the water pump, power steering pressure hose and pump, and fuel filter. I degreased the engine at a car wash and rinsed with the power hose. Now when I drive it chugs/hesitating from stop to accelerate. I took it to a shop who hooked it up to the machine MAF & map sensors working correctly but the computer is not controlling them. What can I do?

Honda - Fit :: 2008 - Stalling / Hesitating When Accelerating From A Stop

My 2008 Honda Fit has been developing a problem for the last 6 months or so and each time I've taken it to the dealership they say there's nothing wrong. It started with the car hesitating when accelerating from a stop. This only happened if the car had been sitting for a while and it only really happened if you hit a full stop before the car had a chance to warm up, even then, it probably only happened maybe 1 out of every 10 stops.

Recently, the car has started struggling when coming to a full stop (again usually the first stop after the car has been sitting) and the car will stall out unless you give it some gas. This seems to be worse if it is cold outside (which it is now permanently cold outside) and when the car is on an incline (front higher than the back).

I took it to the dealership (because it is still under warranty) and they said the engine isn't showing any codes and the fuel pressure is fine (of course that didn't stop them from trying to sell me a new battery). However, I am concerned that this is only going to get worse and its not really acceptable for it to be stalling out regardless.

Ford F-150 - 1997-2003 :: Transmission Hesitating While Accelerating?

Recently, my truck has started rolling back from a stop when accelerating. There seems to be a hesitation between when I depress the throttle and the transmission engaging. It doesn't clunk, just delays. Been doing it for a few weeks, but is now getting worse. Today, the symptoms are similar but more pronounced. When driving there doesn't seem to be an issue, just moving out from a stop.

Checked the fluid idling in park, level was good, fluid looks great, was changed by a shop 6 months ago. Is my 319,000km trans on its way out?

Ford Excursion :: V10 Hesitating After Starting - IAC Valve?

Quite a few posts on this on the V10 forum. Mine Ex has been hesitating after starting (bad after a few days of no use) so I took off the old one and put on a new one. I'll clean up the old one and use it as a backup. Best to lay your body on old carpet on top of the engine, cause this value is right under the windshield, behind the air intake. Took about an hour with some swearing involved. DO NOT DROP tools, screws, gaskets, etc!

First few pics of where it's at .....

Accent MC (2006-11) :: Hesitating With A/C On - Belts Are Starting To Crack

My son noticed the other day that his 2008 Accent hesitates or seems to hesitate when the A/C is on. We have driven it without the A/C on and the car drives like always, no hesitation feeling.

When the A/C is on it seems like it looses power for a split second. I have driven it too and it seems like when the A/C comes on. We have had this car since new and just gave it to him for college transportation so I know this is not normal.

Did notice that the belts are starting to crack and will replace these next weekend but don't think that is it. Not sure if the A/C compressor is starting to go or something else.

Hyundai - Santafe :: 2004 - Random Starting And Accelerating

My 2004 Hyundai Santa Fe with 78K miles has never had any major problems until a month ago. I was doing errands and after my second errand the car would not start. AAA came jumped it, and I took it to a local shop where they replaced the battery. They said the rest of the car seemed just fine. The next week, after gassing up, the car again would not start. It made the same sound, like the engine was trying to turn over or it wasn't accessing the fuel. A bystander thought perhaps it was the oxygen sensor.

After resting for about 10 minutes, the car started and I drove it to a Hyundai dealership. They said the fuel pump needed to be replaced. It seemed fine after the replacement. A week later, the same thing happened. The car would not start. Not after 10 minutes, not after 30. AAA again was called and after I told them about the fuel pump they thought perhaps the relay was bad. They swapped the relay with one I wasn't using and the car started.

I, again, brought the car to the dealer. They inspected the whole car. There were no codes when they hooked it up to the computer and it drove just fine. They simply replaced the relay. Last night, the car made a funny sound upon starting, almost like a hissing or light clunking. This morning the car started fine. I drove for about 5 minutes and then the car stopped accelerating and the power steering seemed off. The car then died and would not start. I was in the middle of an intersection.

After about 15 minutes the cops came and pushed my car while I was in neutral. A few minutes later the car still would not start and it was towed back to the dealer. The car has been with the dealer for over 3 hours. They have driven it, tested it, driven it, tested it while driving. Everything. And they can't replicate the problem.

Chevrolet - 1500 :: 1990 - Running Rough / Hesitating / Lurching And Not Accelerating Smoothly

My 1990 Chevy Silverado with 5.0 liter, 45k miles has started a problem that the guys in my diesel repair shop don't know what to do. Last week it started to run rough, hesitating and lurching and not accelerating smoothly. It idles fine, or pretty well, but just doesn't run smoothly with any kind of acceleration. I drive it back and forth to work just 1.5 miles during the week. I took it on vacation a week before, so it's not from lack of long trips, it ran fine.

A guy at my diesel repair shop put it on his Genesis scope and all it would code is the O2 sensor showed lean, but we could see it switching from rich to lean and so on. I thought vacuum leak, but couldn't find one. PCV valve is good. EGR valve is ok. I changed the fuel filter yesterday and thought it ran a little better, but now has gone back to the rough running. What I can do myself to diagnose this? I do have all the tools and shop.

Toyota - Corolla :: 1997 - Hesitating When Starting / Turns Over But Then Fizzles Out And Dies

My 1997 Toyota Corolla has recently began hesitating when starting. When I turn the ignition, her idle seems normal, but then goes 'down' and it feels like she's going to die. But then the idle/revs go back up and she's fine. However within the past week, she dies when starting (usually the first start or two of the day). She turns over, but then 'fizzles out' and dies. However when she does this, a small tap on the gas pedal revs her up.

This does not occur every time I start her. In fact the more I use her throughout the day, it seems she starts normal. There are no issues with RPMs/Idling when driving.

I've taken her to two mechanics and they could find nothing. Fuel pump, fuel line, throttle body, etc. All fine. When hooked up on the computer the only thing that showed a slight reading is the idle air control valve. But they can't be sure that's the problem.

Of course she hasn't died for the mechanics, just me as it's sporadic.

When I turned her on today she didn't die in the morning like she has all week, however the idle was so low that we were waiting for her to die. Slowly the revs picked up and she was fine!

I put fuel injector cleaner in a few days ago and got an oil change yesterday. That's it.

Accent LC (2000-05) :: Clicking While Accelerating And Slowing Down

My 2005 Accent began making an odd clicking sound about two years ago when I would decrease my speed, not using the brakes. It wasn't loud, just annoying. It went on for some time until my car went into the shop to have the alternator replaced. I explained the noise to the mechanic and they checked it out. They explained they added some type of cleaning fluid somewhere under the hood, and the sound was gone. I was thrilled.

Last year, the sound returned again. Annoyed, I began saving to bring it in to the shop again. In Feb 2013, I had my timing belt and water pump replaced because my mileage of course called for it. The mechanic said he could not hear the clicking sound I was reporting (I really didn't see how.)

Two months later in April, my car decided to die on me and after 5 months I just recently got it up and running again. My differential and transmission were both completely rebuilt. Also, my CV axles have both been replaced. Now that I have my car back, the clicking sound is louder than before and also now happens when I accelerate as well. The faster I go, the faster the clicking gets until it eventually stops. When I slow down, the clicking starts again until I hit my brakes.

I want to take my car and get this noise silenced once and for all since they didn't hear it when my transmission was done last month. What fluid may have been added to what part 2 years ago when this was handled initially?

Accent RB (2012+) :: Self Slowing Down At Low Speed When Not Accelerating

I just bought a new Accent. It seems to slow it's self down at low speed when not accelerating. In other words, it does'nt coast freely. Could this be a sticking brake caliper or a transaxle problem? Could it be related to the slippery road condtions feature on/off?

Santa FE SM (2001-06) :: 2004 2.7L V6 - Hiccup Type Sputter When Accelerating After Starting The Vehicle

My car has three codes P0102 - MAF or VAF Low Circuit Input, P0030 & P0050 which are signaling O2 sensor issues.

Car symptoms are a hiccup type sputter when accelerating for the first few times after starting the vehicle. The RPMs will drop down under 1000rpm and it will come back without taking my foot off the gas. The power comes back faster if I flutter the pedal. The last few times it stalled while taking off.

After the car is warm, it runs better smoother. I'm also noticing slightly poor fuel economy. The exhaust smells rich to me.

I'm wondering if there is a fuse that could cause all three codes? Seems like a power problem? Where is the fuse for these sensors?

Should I replace MAF? Can I use the MAF from a 2004 2.4L engine that's at the junk yard? How to proceed.

Touareg :: Engine Move When Accelerating After A Stop Or After Slowing?

Are the mounts on the engine not tight enough? It feels rather strange. My dad's Ford Explorer doesn't do that. I feel like I'm driving a car with a manual transmission that needs to have dogbone bushings and mounts upgraded. How do I bring this to dealership's attention without appear like a complete loony? They like to give the "Could not duplicate" response when there is an obvious symptom.

Ford - Contour :: 1999 - Jerking While Driving Accelerating Slowing Down

I was driving the car yesterday and was getting on the highway ramp and stepped on the gas and car went crazy. It started to accelerate and decelerate by itself. I had no control of the car whatsoever. When driving at 0 to 40mph no problem so far, but anything over this car will jerk, like it's changing gears by itself, 'going fast and slow.'What is this? Do I need a fuel filter, or plugs or what? I don't know when the last time I changed anything the car mileage is 135,000

Lexus ES 2007-12 :: ES350 Jerks Sometimes While Driving When Accelerating Or Slowing Down From Speed

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.
