Mazda :: 2007 - Sluggish Acceleration / Stops When Foot Is Off Accelerator
Aug 2, 2013
I have a 2007 Mazda 5 and over the past few days, I notice the acceleration seems slightly sluggish, especially on inclines. Then last night I had a problem where I was driving and whenever I took my foot off the accelerator, the car would stop (rather than gradually slowing). And when I put my foot back on the accelerator, the car jerked forward before finding the right speed. I parked and after work, it drove just fine. Drove fine this morning also. The shop says I need a new solenoid purge valve, but after reading about that valve, I don't understand how it could cause my problem. The car didn't stall whom it stopped, it just stopped moving forward.

I was on my way home suddenly the acceleration of the trib went sluggish.... low idle especially when you put it on drive and with the a/c on. It can rev but it feels like you are revving a 1.1L engine.
What could be the cause? I already had the sensors etc cleaned 6 months ago.....It has NO check engine light.

Car Details : 2004 Mazda 6 V6 3.0 L engine automatic transmission with 88,000 miles
Car Problem Vignette : After driving for a bit, say 20-30 mins (after my engine gets hot), I start to smell a burning oil smell. I’ve looked under the hood at my engine and do notice some oil leaking from the engine. This is not just some simple oil leaking after an oil change. The oil appears to be coming out of the engine "seams" itself. This has persisted for some time now. This problem started at least a year and a half ago now (12/05/12). I’ve had a mechanic take a look at the oil leak and supposedly he fixed the head gasket or valve cover gasket (I’m not sure which one), but the problem never fully resolved.
In a related or unrelated situation (I’m not sure yet if it is related) during this time my car started to jerk and sputter when I drove, so much so that I wasn’t sure it was going to make it to work one morning. The check engine light came on and I eventually made it to work and back home that day. It gave me a code that said one of my cylinders was misfiring. I proceeded to change all of my spark plugs to no avail. I then changed out one of my ignition coils to the bad cylinder misfire. It fixed my problems with the stuttering and I could drive my car again without fear of stalling. However, I still smelled burning oil. Over time I eventually started to feel my car struggle to take off during acceleration which felt different from when my car seemed like it was going to jerk and sputter to a stall. During this time frame one day I was at a stop light and when I went to take off, a huge plume of bluish / white smoke came out the exhaust and I smoke-screened the people behind me. After that incident, I ended up changing my positive crankcase valve (PCV). After changing my PCV my car felt like brand-new again! I could not believe it! My car started accelerating smoothly and driving so much better. I felt like I had gotten the “Zoom Zoom” back for my Mazda.
Sadly this didn’t last long, maybe a month at the most. My car started struggling during acceleration again and I started smelling burning oil again. I have dealt with this for over a year now. My car still runs and gets me around, but I can’t remember the last time that my car ran smoothly or didn’t smell like burning oil except for that time I changed the PCV. I have never seen any kind of smoke coming out of my exhaust again like that one experience.
Problems:
•Burning oil smell coming from my engine due to leaking oil coming out the "seams" of the engine
•Car is struggling when accelerating especially at lower gears
•I feel it every so often when I accelerate somewhere between 2nd and 3rd gear that the car jerks and makes this “chunk” type sound and feeling when it shifts gears.
Questions:What is wrong with my car? Are all these situations related? And what do I need to do to stop the oil leak and acceleration problem?

Experienced sluggish acceleration with their "09" Santa Fe. I have the 2.7 liter 6 cyl. engine and it seems so sluggish when accelerating. I have replaced all the plugs with some best rated ones specific to my model. I have tried one of the best rated fuel system cleaners. It still seems to have no pep, my daughter's 1999 Honda has far more get up and go.

I have an 08 460 LS. I am experiencing sluggish acceleration. It feels like the car is in the wrong gear and has no power. This is intermittent and most of the time ok. Occasionally it is jerky when pulling out when it has proper power.

The engine continues to rev after I take my foot off the accelerator. Does it under many different conditions, but especially the engine needs to be warmed up for it to do this. Toyota just called to say there is nothing wrong with it, even though I had a technician drive it and tell me "this is messed up!" Apparently the master technician that worked on it today didn't have a clue. Under warranty and will fight it! What is wrong with the car?

It seems to me my Prius 2007 decelerates noticeably when I take my foot off the accelerator. It's noticeable but not even near the level of the engine braking in B mode. The change seems to have happened since my last service but the I won't swear to it, and the dealer says there hasn't been a software change.

My sister's 1991 Volvo 240 automatic. She is scared to drive it. When we push the accelerator fully down while in park the car makes a sound of accelerating hard and decelerating, it occasionally makes the sound of a backfire. All the sounds are coming from under the hood. When in drive it will not actually accelerate past first gear, it will buck back and forth, and still makes the sounds. Its almost like a shutter. Reverse is the same. We recorded the sounds.

Ever since I got a brake job, my brake lights have come on, all 8 of them. Traction Control, ABS, Brake, etc. Every once in a while they will go off and be normal for a day or two then they will come back on. The service center that did the brake job said everything looks good, it must be a faulty brake actuator.
The brakes work fine although on starting I have to remove my foor from the petal and then reapply it to move the transmission from park to drive. When on the highway doing 70 mph or so, when I take my foot off the accelerator I hear a pop coming from under the rear of the car mostly on the passenger side. In about 5 minutes, I'll hear it again. It sounds like pressure is being built up than all of a sudden released with a pop.
Actuator replacement and I rather not go through the expense if it is air in the brake line of a faulty sensor.

So I have a 2005 Camry XLE, 3.0 l V6 with 160k miles. The car was running fine, but I decided to change the spark plugs today (overdue).
I went through the headache of removing the intake manifold, throttle body etc and everything seemed to go OK. I reassembled it all and now it won't idle properly.
It seems like a vacuum leak issue to me, but I have double checked the multiple hose connections. I did NOT disconnect the battery at any time.
I can Rev it up to 3 or 4000 rpm and it runs smoothly (all the cylinders seem to be firing) but it runs rough and dies without my foot on the accelerator. Also I noticed the exhaust manifold got cherry red like right now... after only a minute or two of running.
Are there any troubleshooting checks I can perform to narrow down the source of the vacuum leak?

I have a '92 toyota camry that we just purchased and put a new engine in... now it's stalling when you come to a stop and are taking your foot off the accelerator. we've tried a fuel injector, a fuel clean, fixed vacuum leaks, and replaced the fuel filter, and fuel preside regulator... it's still doing it and is getting worse.

I have a 2001 F250 7.3 with 175K.
Here is the situation. There is a disturbing clunk when I take my foot off the accelerator and a corresponding clunk when I push back down on the accelerator. This only occurs when the vehicle is not under load. That is, it does not happen when going up hill or on any sort of an incline. It does not happen when the automatic transmission shifts. It does not happen shifting into reverse or drive.
It does not happen when starting or stopping. It only happens when I am at 40-60, or so, miles an hour and let off the accelerator and/or press the accelerator again. It appears that I can carefully feather the accelerator to eliminate or, at least, minimize the clunk. I have crawled under the truck and it looks like all the U-joints are tight, I have lubricated the slip-yoke (although when twisted there is, like a mm of play when this is twisted, not much but a very little).
The rear-differential pinion appears to be tight (no side-to-side play or up-and-down play, or at least I can't make it move with my hands). However, when the truck is in neutral the entire driveshaft is able to rotate a half inch, or so, all the way up and down the drive train. That is, the transfer case and the rear differential appear to have a little rotational play in them, but I am guessing this is pretty normal. When in park the entire driveline seems solid.
I have seen from some of the other posts that this sort of clunking can come from leaf springs, hangers and such but since this clunk seems so isolated to acceleration changes when the vehicle is not under load, I doesn't seem like this would be the issue. No clunk when shifting, turning, bumps etc. Everything seems perfect until I am on a gentle downhill or flat and let off the accelerator. Doesn't appear to clunk when going down a steeper decline. All this gets me to thinking that the clunk is caused whenever the driveshaft rotation gets ahead of or behind the rotation in the rear differential.

After putting my front end back together except new springs, new shocks, and new track bar, just to give everyone a little history of what I've done to it. I've had it for 8 months and maybe put 1000 miles if that because of working out of town a lot and the front end torn apart. I've noticed a louder roar coming from the rear end when taking my foot off the accelerator without pressing the brake. It feels like the tow button is engaged, but isnt. I have no issues with handling besides knowing it still needs alignment. I'm taking it to the dealership tomorrow for a 4 wheel alignment. It sounds and feels like I'm riding on mud terrain tires.

I recently acquired a 1984 AMC Eagle and I'm having trouble getting it to start. It turns over but the engine stops running unless the accelerator is kept depressed. Also, the car stalled at a light the one time I did get it running, so I'm thinking that there are some issues with the idle or with the carburetor maybe. I live in Colorado and I gather that the idle on these vehicles needed to get adjusted for the altitude, but I assume this has been done already as it has always been a Colorado car and has 125K miles on it. The gas is low, so possibly it might be something as simple as a gas supply issue, but judging by what other owners have posted online, it seems that this stalling problem is common with the Eagle so I think it probably is something more involved.

Bought this truck a few months back. Nothing but problems. I always thought it has felt a little underpowered and hesitant. I chalked it up to being a 5.4l in a f250. Well now im thinking it has been a symptom all along.
Lately, the truck has been stalling at stops. Randomly, but not often. The truck idles at 750rpm when I start it, but after driving and then coming to a stop while in overdrive it idles at 400rpm. This seems too low to me.
It hesitates occasionally when giving it throttle. Just today it got really bad and was almost unresponsive. I would hit the throttle and it would just idle while randomly kind of shooting up in RPS and shuddering. It finally produced some error codes, it looks like, but I am afraid to drive it all the way to the autozone.
I am thinking TPS. Is the TPS attached to the pedal or is the TPS attached to throttle body under the hood? I've read some conflicting stuff about this. The good news is that if it is the TPS then it should act like a whole new truck after I replace it.

I have a 2004 F150 4.6L... There is a slight hissing sound under the dash on the drivers side when you lightly press the accelerator and then stops. No matter what speed you are going as soon as you apply the accelerator it hisses then stops. There is also the same hissing , only louder when the engine is cut off. It hisses for about 3 seconds. What could be causing this. It has been idling rough since the hissing started. The check engine light is on and showing P0420 and P0430 codes . The cats were replaced with resonators so I believe that is the reason for the codes.

I have a 2001 Mazda 626. It has stopped unexpectedly while moving 2 times in the past 3 1/2 months. When it stopped (both times) it was mid-day, the a/c was on and I was moving at a low speed (between 5-15 mpg). When this happens, the gear shift locks up and the car won't move. Then after about 15-20 minutes it starts right up!
The car has been checked by my regular mechanic both times, who is terrific, and although he ran a diagnostic both times, found no electrical problem. He's convinced it's some kind of simple mechanical issue but hasn't be en able to diagnose what and isn't inclined to just start replacing any/all possible parts without a definitive reason.
The second time the car did this the Mazda dealership also did a full diagnostic and only reported "repairing" a couple of the battery wires, did not replace anything.
No one knows what's wrong but if the problem isn't resolved soon I will have to get another vehicle because I no longer feel safe in the car.

I have a 2003 Mazda 6, 5-speed manual transmission. I was driving on the highway today (going about 65mph), and all of a sudden, my car kind of "jolted" (like it stalled out). When I tried pushing the gas pedal, the car wouldn't accelerate. When this happened, the check engine light (and some other lights) went on, too. I pulled over to the side, turned the car off, and turned it back on. It seemed to start fine and gas/acceleration was working. Fortunately, I was able to get home, but it started doing it more frequently up until I got to my apartment. Each time, I had to turn the car off and restart it.
Oddly enough, when the car does this and I pull over to the side, the engine is still on. However, even though the engine is on and the car is idling, I noticed the RPMs were sort of jumping between 0 and 1000, and the engine was sputtering (like it was sputtering with the RPMs jumping, the only way I can describe this sputtering is like a heart beat). The only thing that seems to work is to turn the car off and turn it back on, which will then allow the gas pedal to work, only to have it happen again a few minutes later. The gas pedal doesn't get stuck or anything, it's just pushing it doesn't seem to accelerate the car.
I've already had the engine replaced on this car last year (at 80K) and the clutch a few months ago, too.

Well, I just went to grab some lunch and on the way home I got on it a bit. I was met with sluggish acceleration and a flashing CEL. Before I could even turn the car off, the CEL went away. I was about 200 yards from my house so I coasted home. What could the issue be?

I drive a 2001 Hyundai Accent. About a month a go the CE light came on. at first, the car was driving fine so I thought nothing of it. Then I started noticing that the acceleration was sluggish and when it finally accelerated, it basically slingshot forward. What could be wrong. There's no smell, rattling or anything else. The only thing I noticed was the engine was a bit louder.
