Santa Fe (CM - 2007-12) :: 2009 - Rough Idle / Random Stalling
I am happy to own a Hyundai Santa Fe (2009) 2.7l which originally originated in the US. It is a really nice car, however, it recently over time developed the problem, which causes some pain - firstly it started with rough idle (pulsating), now it began to stall from time to time when decelerating.

I tried to plug a OBD reader and here's what I get (well, that's a "pending" fault, but still might be useful).
I tried to browse around the internet. I believe it is unlikely that 2 oxygen sensors fail at the same time. It could possibly be caused by vacuum leaks or faulty MAF. Is it a common fault among Santa Fe?
Ford - F150 :: Sputtering / Idle Rough With Surges
I have a 2001 f150 5.4 liter 2 wheel drive super crew that idles rough with surges in the idle. Weird thing is it only does it when it's 55 degrees or below. So it's fine now in the heat but winter is coming and the colder it is the worse the idle. Replaced maf sensor.

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.
Tiguan :: 2009 - Stalling Out After Startup / Hum Lasts For 5 - 10 Minutes After Shut Off
I'm the owner of a 2009 4-motion SEL with 85,000 kms....recently it has been stalling out after startup. Sometimes this occurs after driving away, but most frequently before. It usually works fine after a couple of starting attempts. I've read through some posts regarding the high pressure fuel pump as a possibility. I've also noticed a pump or fan type hum that lasts for 5-10 min. emanating from the rear of the vehicle after shutting it down. Not sure if this is normal or could be related?
View 2 RepliesDodge - Stratus :: 2006 SXT Rough Idle - Slight Sputtering Noise When Not In Motion
Today I went and test drove a used 2006 Dodge Stratus SXT from a private party. Everything about the car was great except it had a bit of a rough idle; there was a slight sputtering noise when not in motion, and the car itself vibrated very slightly. It didn't bother me too much while I was driving because it accelerated and shifted fine and the engine sounded very strong, otherwise.
When the test drive was over I pointed out the noise to the owner, and he admitted that he had mis-timed the timing belt slightly which was causing the sputtering (he is a mechanic and replaced it himself). I was worried about this, but I did some research when I got home and learned that this model of Stratus has a non-interference engine.
My question is this: should that timing belt be a deal breaker for me? Will this cause major mechanical issues down the road? I know it will reduce power but I only really need the car to commute, so I don't mind if I'm not toe-to-toe with a Challenger. I'm just worried it will eventually cause a costly problem.
Sonata I45 (LF 2015+) :: Rough Idle With Engine Sputtering - Fuel Injector Failure
My new 2015 Sonata 2.0Twith 8000 miles started running oddly about 2 weeks ago. Rough idle with engine "sputtering". Erratic acceleration -- merging into traffic on highway and car not going over 40mph, even with gas pedal all the way to the floor. On deceleration, clunky down-shifting. Very hard to drive. Dealership first came back with diagnosis of "buildup on throttle plate" (Note - I use only high-quality gas AND only have 8000 miles on car, 3500 or that being one long highway road trip). Then, after 3 days of diagnosis, they say I need 2 new fuel injectors I am baffled how a new car can have either buildup or failed fuel injectors...

I replaced my EGR valve vacuum check valve, but now started getting sputtering/rough idle. I'm pretty sure the direction of the vacuum check valve is correct, but I tried both ways to be sure and still got the sputtering at idle.
The old vacuum check valve didn't give me the sputter. I only replaced it because it was melted and I'm not sure it was working. I included a photo of it. It's orange and black.
Nissan - Maxima :: 1996 Keeps Stalling And Idle Rough
My car has suddenly started stalling a lot. I can get it to start right up if I put the clutch to the floor and it will idle fine until I start coming up of the clutch even while it in neutral. At times it will idle in neutral then start to idle rough and stall. I can drive it in reverse but can't drive it forward except in first if i keep the clutch at a certain point and not release it all the way. However when I try other gears sometimes it's like it does't want to go stalls. What it might be?
View 1 RepliesFord - Explorer :: 2003 4X4 - Very Rough Idle - Stalling If Let Off The Gas
Bought a used 2003 Explorer 4X4 that runs like crap.... All I know is it has new upper and lower radiator hoses, new battery, new brakes, 2 new tires and new belts... suspension seems great and body is nice too. It obviously needed a new radiator and complete exhaust, so I did those. Now it is running better ( I can actually get the RPMs over 1500) but still running rough and will stall if I let off the gas. It will surge and dip in RPMs. Very suspicious of vacuum leak.
Unplugged the MAFS and it roared upon start but within a minute started the sputtering etc. Currently pulled the IAC and check continuity between pins and it was 10 ohms so that passed but there is no continuity between either pin and the case. So this seems to indicate I need to replace the IAC which I will do tomorrow. I would love to find a diagram that displays the vacuum system so I can make a thorough check of it. Also seems to have an oil leak on drivers side valve cover gasket.
Tiguan :: Idle A Little Rough - Check Engine Light On
New 2012 Tiguan S with a manual, 800 miles and the check engine light comes. Seems to idle a little rough, at least the idle seems to fluctuate a bit. The real disappointing part is I took it in to the dealer expecting an easy fix within an hour, its now been at the dealer for 2.5 days and they'll have it over the weekend as well. They tried putting several parts in it, still didn't fix it. They called VW who said pull out the new parts, put back the old parts, and apply some software update. Dealer did that, still not fixed.
View 7 RepliesSaab - 9-3 :: Rough Idle And Loss Of Power - Stalling On Start Up
SAAB 2007 9-3 - Recently my car has been having a rough idle and stalling on start up. It has been getting worse and I need it fixed ASAP for a long trip coming up. I cannot have this thing die on me while I'm 300 miles from home....
At stop lights the car will have a rough idle while in park and reverse. While in neutral, nothing. As soon as I accelerate, it goes away but does have a lack of power if I really push the pedal. Once I am in 3rd/4th gear, the car feels normal with no issues. If I am on the highway and slow down then need to accelerate, it goes back to losing power BUT if I change over to manual and downshift, car gains power and goes back to normal.
Here's what I have done so far:
1. Changed the spark plugs twice. Once with cheap ones, the second time with expensive ones. I also swapped out the boots.
2. Cleaned the MAP sensor
3. Cleaned intake sensor
4. Replaced air filter
5. Changed oil
6 New battery
The engines gives no codes whatsoever and I have taken it to a couple places and their readers don't see any codes. My SAAB has a built in fuel filter and this cannot be replaced unless you replaced the whole pump (to my understanding). I plan on buying some Seafoam today and see if that works. Also, I have been told to clean my air intake valve but I cannot get the damn tube off! I feel that if I yank and pull on it, it's going to damage the tube. I am not seeing any obvious leaks anywhere. One thing that is weird about my car, since I have bought it used a few years ago, my headlights/tail lights/blinkers go bad QUICKLY!
Golf IV R32 :: Very Rough Idle And Stalling - Throttle Response Is Very Slow
I finally finished installing my VF stage 2 supercharger. I fired it up and the idle is low (around 500 rpms) and a very rough idle. Throttle response is very slow, when it finally revs the car stalls. I can also hear a leak somewhere near the throttle body. I have an SAI block off plate. 630cc injectors and UM tune. No CEL
View 3 RepliesOldsmobile - Cutlassciera :: 1996 / 2.2 L4 Running Rough Idle And Stalling
1996 / 2.2 L4 / 186k / Upper engine rebuild 30k ago
Car was driven on a errand by my mother. Upon trying to leave for home, the car started running very rough, and stalling. From the description she gave on the phone, it sounded like a plugged up exhaust. I told her to get some fresh gas and ease it home after.
When I checked the car for codes, I got 2. A P0300 and a P0122. Okay, so the throttle position switch has taken a dump, that's easy enough. The car has 186k miles, but my constant nannying usually soothes her, so surely that's all, right? God, I wish that turned out to be true.
I pulled the plugs, and #4 was gas fouled and sooty, #2 and #3 looked lean, and #1 was partially wet fouled. There was also gasoline in the oil. When the car would run, it would run the gambit from idling semi rough then stalling out and refusing to restart, almost like it was flooded, to idling scarily bad and no pedal response, to running too high of an idle and idle searching.
Since I have:
Replaced the TPS
Replaced the IAC
Replaced the CTS
Replaced the MAP
Replaced the ICM
Replaced the FPR
Replaced both ignition coils
Replaced plugs and wires
Replaced the fuel injectors
Replaced the PCV
Replaced the fuel filter
Checked the pintle on the EGR (looked good, cleaned)
Checked for Vacuum leaks (as best I could)
Checked the Fuel pressure (40 PSI) (drops to 20 after shutoff)
Checked for exhaust restriction (ran open exhaust manifold)
That brings us to today. New injectors just in, and the engine will run, but rough and loud. It almost sounds like the firing order is off slightly (I am using 1342 or from L to R 4132) and throttle control is almost non existent. It also shuts off when its warm almost like its flooded. No codes are showing. (despite discovering a sensor in back being unplugged and the O2 sensor being unplugged at times).
Jeep - Grandcherokee :: Engine Occasionally Run Rough At Idle / Low Rpm Before Stalling
I've got a 1998 Jeep Grand Cherokee, 6 cyl. engine, ~145k miles. A few weeks ago, I noticed the engine would occasionally run rough at idle, dropping down to a low rpm (~500 rpm, but erratic) for a few seconds before stalling. This usually happens when in park or stopped at a stoplight, but it's occasionally happened at low speed while coasting to a stop (never while accelerating, or while traveling above 20 mph or so). Generally, the car will restart right away, though sometimes I have wait a few seconds to a minute (I was a real popular guy at that intersection).
At first, no codes came up, so I changed the plugs and wires (I was due anyway). That didn't work. (The plugs, while worn, looked normal to me-no residue). I've since had a P0351 code pop up. Before I throw parts at this code (ignition coil, I believe), is there anything else I should be looking into?
Passat (B6) :: Rough Idle / Stuttering And Stalling At Stop Lights
My vehicle has started to idle very rough, stuttering and almost dies at stop lights. It hesitates when accelerating, and really shakes and rattles if the AC is turned on. The check engine light and EPC lights are on. And even letting the foot off the brake in drive causes it to jerk along. I am up around 65k miles and have not had too many issues other than a fuel pump getting replaced last year. (the dealer first started replacing and charging me for many other items) I am scared to go back without trying to trouble shoot it myself.
What it could be and if there is anything I can try to correct it myself?
Santa FE SM (2001-06) :: Car Has Hard Start, Rough Idle With Stalling
My coworker is giving me a clean 2001 Santa Fe with 151000 miles. It was running fine then all of the sudden it lost power but was able to stutter home. I went to check it out it started fine but idled a little rough. When I revved the engine it rose to about 2500rpm and stuttered then stalled. Kind of like it was rich and choking out. It then had difficulty restarting.
View 10 RepliesWindstar :: Rough Idle Only When In Gear Leading To Engine Stalling?
This is a little odd. Over the last two years or so the van had developed a rough idle issue. When left to idle in Park or Neutral the roughness would usually lead to the engine stalling after a few minutes.This happened both in and out of gear but only when the engine was still cold, idle returned to normal once normal op temp had been reached. Cleaning the IAC got rid of the problem... sort of. Now it idles fine in Park or Neutral but when in gear and engine/tranny still cold it is still very rough.
When waiting at a traffic light with my foot on the brakes the van shudders as it tries to lurch forward, the shaking is very noticeable even to those outside the van. This has become so bad I shift it into Neutral every time I need to stop at a traffic light, and it instantly settles into steady smooth idle at 800 rpm. However once the engine is warm everything returns to normal. Another thing I noticed is that when in gear and cold the roughness only occurs with brakes applied. Feels like whenever the roughness in the engine occurs the transmission attempts to override the brakes, which causes the lurching.
While the problem only lasts 5 to 10 minutes until op temp is reached it is nevertheless very annoying and driving me nuts. My main concern is that it may eventually cause damage to the transmission to be tugged at and jerked around in such a way. I am running out of reasonable explanations as tho what may be causing this and have begun elaborating more esoteric theories. My latest one is that since this only happens when the brakes are applied then the tiny voltage required to activate the brake lights is somehow causing some other electric part to fail, and that the rough idle is somewhat related to this. Shows you just how desperate I'm getting.
Stalling - Mazda - Mazda6 :: 2006 - Run Rough And Idle At 1000 RPM?
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?
View 5 RepliesFord F-150 (2004-2008) :: 2005 - Rough Idle And Stalling
I have a 2005 5.4l f150. 105,000 miles. Recently While on a trip I experienced rough idle and stalling at idle. I drove it home 2hrs. The ride home was challenging. Poor acceleration, rough idle. Took it to the dealer and was told I needed plugs and I was 5qts low on oil! Not sure where the oil went. It hasn't been leaking and never seemed to burn oil in the past. They did the tune up. Picked up the truck. It ran fine while cold. Upon warming up it ran rough at idle and stalled just like it did before. Took it back, they said "you need a new engine. Upon warming the oil pressure drops indicating internal engine damage". I took it to a local guy he says replacing the cam phasers might fix it. What's the consensus, should I try the cam phasers? Look for some other potential problem or trust the dealer? (They did refund me for the tune up)...
