Stalling - Mazda - Mazda6 :: 2006 - Run Rough And Idle At 1000 RPM?
Jan 28, 2011
I have a 2005 Mazda 6. When it is cold - I start the vehicle & begin to drive. When I slow down and the RPMS get around 1000 - the car begins to run really rough & try to stall. If I put my foot on the gas - I can usually prevent it from stalling. The problem disappears once the car gets warm. The dealership recalibrated the PCM based on a Mazda Alert. However, it has not corrected the issue. Looking for thoughts on what could be causing this?

I have a 2008 Ford Focus - 4 Door Sedan SE 60300 miles.
I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.

I have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.

Mazda6. I have a check engine light for a random misfire on cylinder 2. I have changed the spark plugs, the injector, and even the cylinder 2 coil, but still have that random misfire. The funny thing is that it would run great within short (about 30 miles) one way trips. Lately, I have gotten a new symptom: It has started to hesitate and can feel a loss of power but only once the car has been driven for about ten minutes non stop. Can't figure this out.

we have an 2006 Mazada 6 automatic transmission with the option of manually shifting gears. we have had it a year and the only maintenance is work on the air conditioner, oil changes, and new tires. when accelerating on an incline or sometimes during/after a curve as it shifts into 4th gear it makes a terrible noise and the whole car jerks. the best way I know to describe it is it feels as if the bottom of the car is about to fall out! when we first purchased it, it done this a couple times and basically quit doing it for a few months.
It seems to be getting worse though. we have never had a check engine light. we sent a can of "sea foam" through the gas tank and this seemed to work. a local mechanic examined it and test drove it but couldn’t find anything wrong with it. (of course it didn’t act like this when he drove it!) I called mazda dealership and they cant tell us anything without us bringing it in and charging us no telling how much just to look at it. no one seems to be able to figure this out….

I have a 2006 Mazda 6 that ive owned for a year now. It has this random problem tho.... when accelerating into 4th gear it makes a horrendous racket like the bottom is falling out of the car or something and sorta jerks. it has been doing this a long time. other than that it drives fine! i have no mechanical knowledge about cars so im totally clueless! this seems to happen when accelerating on an incline.

I have a pretty bad flex pipe leak on my 20th. Would this leak cause a very rough idle almost stalling when I come to a complete stop. The Idle fluctuates from almost stalling to 1000rpms.

I'm a diesel mechanic and know my way around Powerstrokes, this 4.0 is not what I would usually work on, but I have a friend who has 2006 explorer 4.0L SOHC, someone told him he needed a motor with out explanation why, so I didn't want to see him get ripped off. The problem is it idles very rough, hard to start, and stalls. There's no DTCs , if you hold the accelerator slightly it will stay running, but once you let off it will either idle really bad and misfire or cut off, once pushing the accelerator the rpms raise very smoothly up til 3500 which is what I assume the rev limit is in nuetral.
I've done checks with focom and forscan, I was thinking possibly a bad fuel pump, while monitoring fuel pressure I see a range of 289 - 326 kpa with 26% fuel pump I guess duty cycle would be the correct term(once again I'm a diesel guy, and use to dealing with IPRs and Hpops) not sure if the desired fuel pressure is relevant on these but it always stays at 269kpa. I believe that equals out to 40-48psi while I believe this system is supposed to have somewhere in the range of 60 - 70, but I wouldn't expect to get a rough idle with no load with almost 50 psi of fuel pressure.
So with no DTCs Im baffled, and don't want to start wasting money just throwing parts at it. I've thought everything from fuel pressure sensor, to coil pack(replaced 4 months ago) to crank and cam sensors.
I did end up getting a code p106, but I believe this is because I didnt tighten the intake hose after checking the throttle bottle, I just slid it back on. out of the 4 days of testing first time I seen a code pop up besides unplugging some sensors here and there to make sure the pcm would actually register a dtc.

Audi A3 3.2 owner here from Fortitude and have rough / lumpy idle issues? While at a stop in neutral w/a cold or warm engine, it seems a little rougher than one would expect. If you rev it to 1000-1100 rpm the whole car shakes.
Engine Mounts worn?
APR Software causation?
Cam Followers or faulty coils?
Do I need a heavier duty front and top engine mount?
Wondering if CAI and Exhaust along w/ the APR ECU tune is causing it or if I'm just being paranoid.

2003 Elantra gt 90,0000 miles manual transmission. Rough idle under 1000 rpm it smooths out completely above 1000 rpm.
Also the engine makes a ticking noise from a cold start up. It stops making the ticking noise after 1500rpm or when the engine warms up.
Occasionally the car has a sputtering backfire. This happens when I park the car after being on the highway.
Replaced the plugs, wires, and the pcv valve. Dropped the oil pan and it and the oil pump pick up screen were clean.
The only check engine light to come on was for the speed sensor. It has since gone out on it's own.

Starts fine. Runs fine till warmed up. Then dies at idle and runs rough on gear till 1000 rpm. Has only coded iac when unplugged. But would idle with it unplugged. I replaced it. Also got crank can code once while checking it ...
2001 dodge ram 1500 318 engine ....

2010 F150 ... So I have the tick noise at rpm's 800-1000 at drive through, stops, etc. So I did research on it a few months ago and saw that it might be VCT's but should be able to drive. so I drove it waiting to save money and have it go to a shop. well this past weekend while coming home from work my oil light came on the pressure dropped to zero, I was on the highway so I drove about another mile to get off highway and once I got off my truck died. I had it towed to my house and I thought I blew my motor. So I started doing research here and found that the VCT's AND cam Phaser could be bad. so I replaced my VCT on driver side put it all back together it started and loud knock was gone. then after 5 mins it was back very loud knock!
So I shut it down and took apart the passenger side once I got the valve cover off I found the problem.... The bolt that holds the cam phaser in place snapped off and was riding along the camshaft. So I took that out and extracted remaining part of bolt. inspected my camshaft and it was really messed up. so I bought new Phaser and Camshaft. the camshaft just came in today and I am trying to put it back in. but the hole for the pin in the phaser doesn't line up and I cant spin the shaft to make it line up. should I spin the cam phaser? I marked the chain and the phaser is where it should be on chain, but with that bolt snapping off could that have thrown the timing off so my mark is no good? when I lay the camshaft in place it sits perfect and if I just move the phase over 2-3 links it will all fit together. Should I do that?

My '04 v6 wagon 100K will misfire in really damp conditions. Last fall after going through a massive puddle and today after sitting for a couple of days of warm damp foggy & rainy New England spring weather. OBDII scanner is reporting cylinder 3 as the one misfiring in the fall, today there were a ton of codes (that I didn't note).
So I made it about 2 miles from the house and had to turn back. No power, check light flashing. I had to put it in manual and keep the revs highish (3-4K). When I got home the exhaust manifold was glowing yellow, assuming one or more cylinders were passing fuel out to the exhaust and it was being burnt off in the manifold.
My question: could I have damaged any gaskets back there? This could be my imagination but I think I'm hearing a new noise that I'd normally attribute to an exhaust leak downstream of the muffler, very subtle - like a gentle light but rapid thud. I only hear this noise with my ear to in the front driver's wheel well. There's no ticking noise I normally attribute to leaks near the manifold. My imagination or is it easy to damage something in the circumstances I describe?

My son's mazda 6 will turn over but not start. the things I have done:
1. replace crank sensor
2. replace cam shaft sensors
3. it has spark
4. fuel pump works
5. sprayed starting fluid in still will not start.
What else should I check? Security system?

I have a 2007 Mazda 6 with 133000 miles on it. Recently it has started making a very loud sound that comes from under the hood. The sounds is comparable to the sound a semi truck makes if it is idling. The noise is not constant, usually happens when I put the car in park or if I'm driving at low speed (under 20mph). The sound lasts around one minute.

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.

2009 mazda6, I feel some vibration feels like wheel is out of balance coming from the front left wheel, it's most noticable at 30mph and again at 60mph. It's more noticable when i'm turning right, e.g. shiting to the right lane.
Already replaced four tires, balanced the tires and replaced front struts and rear shocks.. and it's still there!!
when shifting to the right lane, the vibration feels like da-da-da-da-da.. like I'm driving over some washboard road.
What could this be, is this CV-joint? can I ask dealer to check out CV-joint see if it's ok?

Can a problem elsewhere in the system cause ignition coils to go bad? I have an '03 Mazda 6s, 147k miles, owned it since new (Dec '02). 3 1/2 ~ 4 years ago, over a period of 6 months I had to replace 4 of the 6 coils. A month ago, one of the replaced coils went bad so I had all three rear bank coils replaced (cheaper to do all three at once rather than one at at a time since half the engine needs to be disassembled to get at them). This week, I started to get the initial symptom of a coil going bad on me: Occasional stuttering in the engine.
This issue always starts when it's wet outside. The first few times it started when going through a car wash, this last time was right after Super Storm Sandy dumped a lot of rain (I am not in one of the flooded areas, NH just got a lot of rain).

I have a 2003 Mazda6, 108K miles. Had the ATF changed last December at the dealer. Prior to this, there was some hesitancy to shift into 1st when cold. Last several months, it has gotten worse. Engine revs (as much as I allow it, which ain't much) and then goes into first. Dealer thought they had overfilled the ATF, and reflushed and refilled. Said they couldn't find any other problems. There is no CEL. Problem was better for a short while after fluid change, but now back to long hesitation. Car goes into Reverse fine when cold. Once the car is warm, I don't notice the hesitancy to shift to first. How to diagnose?

MILEAGE: 65,000
Last time I was in, the shop replaced my sway bar links, which had already been diagnosed and the repair scheduled. Then, after replacing the sway bar links, the mechanic told me that the control arm bushings were cracked. They already put new struts on the front, as well. So I asked him what else was going to go wrong with my suspension. He said nothing else should need work. He also said that the car was safe to drive for a couple months but I definitely needed to get it fixed.
QUESTIONS:
Is it normal for a car with 65,000 miles to have cracked bushings? I realize that the car is 11 years old; I just wondered how much a car's mileage plays into cracking the bushings and, if so, after how many miles should one expect before cracking occurs.
Does it sound like they're trying to soak me? Why tell me one thing at a time? Perhaps more revenue from the labor side of things?
Assuming the bushings truly need to be replaced, does the community here think there is anything else that should be checked and taken care of at the same time? It is both costly and annoying to have to take the car back numerous times.

once the eng is warmed up and i come to a stop with the brake pedal depressed, transmission in drive the engine idles down to~500 rpm and is rough. if i use the hand brake with it still in drive and remove my foot from the brake pedal idle speed increases and it runs smooth at ~750rpm, apply pressure to the brake pedal again and in a few seconds it's idling rough again. Runs strong in all other speed and load conditions. I thought it was a vac leak in the brake booster so I isolated(plugged) the vac line to the brake booster, and every other vac line but it makes no difference. I removed and cleaned the throttle body, no difference. The only thing that makes the idle smooth out when the brake pedal is depressed is if i remove the fuse for the horn/brake lights(found this out from another blog, but they never said if they were able to determine the reason/solution. Why would removing this fuse affect the idle? is there some type vac solinoid that's activated when the brake pedal is applied?
