Santa FE SM (2001-06) :: Engine Stumble At Idle While Sitting At A Stop In Drive
Oct 11, 2016
Once warmed up, while sitting at a stop in Drive, there is what feels like an engine stumble every so often. Good guess is every 45-60 seconds, so it only happens once, maybe twice at long stops. There is a sudden change in pitch the engine, and the car - for lack of a better term - shudders. The thing I have noticed is that when it does this there is no indication anything has happened with the tachometer - RPMs hold perfectly steady. Additionally, there is no shudder when sitting in park or neutral, only drive.
I initially thought it might be an ignition fault, so when I replaced the balance shaft belt I also replaced the crank sensor. No change in behavior. I did some googling, which suggested the issue might be related to the EGR not closing properly. I changed all the vacuum hoses and removed the switching solenoid to test - it seems to be doing its job. I have not removed or inspected the EGR valve itself. However, because there is no symptom in engine speed and the sensation doesn't happen in park or neutral and only happens when warm, I am starting to suspect the transmission itself is the culprit - I can imagine if the torque converter quickly engaged and disengaged - and a little power made it to the wheels - the same result would happen.
There is nothing else odd about the engine or transmission. No codes. Runs like a top. Transmission always shifts perfectly. Fluid was changed two years ago, about 15,000 miles. What came out looked good as well. I'm okay with replacing EGR components, but I don't want to throw money at the problem unnecessarily. Maybe try driving around with the EGR vacuum hose pinched off or disconnected?

I noticed this past weekend that when I stopped at a stop light for a long period of time, the engine would misfire for a split second, random, just miss for a moment, then do the same after 15 or so, sometimes less. Other times, no issue.

So I was driving along at about 50 MPH and came to a normal stop for a red light. Sitting at the light for approximately 10 seconds and feel the engine stumble or possibly misfire.
I immediately look for any idiot lights and see none, however above the mileage range instead of the pages that are normally shown I see:
LIMIT --- MPH
I drove for about a mile and everything seemed fine, I pulled off into a lot and rebooted the car and now everything is back to normal.

Bought a 2001 from a used car dealership about 2 months ago. A week later it started acting funny. It would often race the rpm's about 2000 when at at stop light and then others times would act like I was out of gas when I would take off. Sputtered and then finally run normally. Then other times it wouldn't start and just crank over and over. After 10-15 times it would fire up and then act like nothing was wrong. It was a total crap shoot whether it would start or not each time.
Took it back to dealership and supposedly their mechanic installed a new fuel pump. Ran like a champ for about another two weeks and then exact same symptoms started showing up.

I have a 2004 Santa Fe, 2.7, 150,000 miles. Have had the car for a month or so. I notice that at times I am getting a strong fuel odor when sitting at idle with the windows down. Why the odor, what should I look at, and is this normal? I don't always smell it, does not have to be a full tank to smell it. No fuel leak that I can see . . . I would think the canister would capture the odor?

I recently bought a 2004 Hyundai santa fe 2.4l with 94k miles. when sitting at a idle it has a slight vibration in the cabin, feels like a slightly rough idle, when you drive the vibration is gone. I also had it throw misfire codes for cyl 2 and 4. I put in new plugs and changed the wires, coils are on the way. When the car is in drive and I put the parking brake on and walk up to the motor it sounds like it has a exhaust manifold leak, but I only hear it when in drive. I guess my question is, could this exhaust leak be causing the rough idle or will this be fixed once the new coils are on?

1987 Ranger and the computer will not communicate. I'm trying to check for codes because of a rough idle and stumble when starting out from a stop. Check engine works but won't flash when using a jumper across the data link. Used a OTC scanner but it only times out and comes up "no data". Where to go from here?

2003 2.4 base Santa Fe with 167k miles. It's having an intermittent stumble while idling and at take off once the engine is hot. I have replaced the plugs, coil pack, IAC, intake and cleaned MAF as well as replaced the PCV valve. Also checked and no vacuum hoses are misplaced or missing.
After some reading it appears it may be the EGR? I ordered it to replace just because I'm running out of things to try to replace without going to a shop.

On light acceleration, it has a light stumble or surge and is very slow. On hard acceleration it makes a lot of noise, but isn't even fast enough. I can feel it shift through the gears, and can feel the converter lock up when it's supposed to. Any attempt to climb a slight hill or pass a car, it downshifts to what seems like 2 gears down, and has a loud roaring noise, but I don't feel the acceleration. At steady speed, it feels like it's hunting for a steady RPM, but can't find it.
I just had a timing belt replaced. Had the mech double check to make sure marks are correct. He did a cranking compression test and said they were all between 165-170 psi (is that a little high for a 150K mile car?). He smoke tested the intake system and found no leaks.
It does have codes stored for cat converter and a lean code-bank 1.

Just bought a 2.0l 2001 golf four door. the previous owner had the car for only a short time. They claimed the CEL came on and the code was for the MAF. He cleaned it and when I test drove the car there was no light or sign of any issues with how the car ran. Today while figuring out why the alarm kept going off(battery died in key fob and i replaced them), it began idling rough. It had just started to rain as well. From what i could find from older thread is it could still be the MAF, TCV/ISV, or O2 sensor. Is there any good way to diagnose without a vag-com cable. Mine wont update its firmware and i'm screwed at the moment in terms of gathering info on the problem.

I recently noticed while driving my Santa fe the car started to stumble.Then a little while later the check engine light came on. Pulled the code came up with p300. It's a random misfire related code.

2002 hyundai santa fe GL2 4 Cyl Automatic ... I noticed that there is a super heavy motorcycle-ish loud noise from my engine when I put it in drive. When it's idle or in reverse or neutral the problem does not occur. but then when I switch it to drive, uber loud noise...which gets louder when I step on the gas.
What has been done so far - replaced spark plugs, ignition coils and plug wires so far...also changed the oil, no fix.
No check engine light at all.....however the battery did die due to someone leaving a light on for days So I am unable to get any code readings.

I just purchased a 2008 passat, 2.0T 6spd manual last night and I noticed today, when sitting at a stop sign it has slight idle issues, (goes up about 200-400rpms) then back down to normal idle. Doesn't seem to be causing any issues, its just pretty annoying, and everyone next to me thinks I'm trying to race them.

Sometimes when my car as sitting at an idle in either drive or reverse the motor starts to make a knocking noise from the back of the motor towards the firewall side on the top of the motor. I have a video. The car has 114k I just changed the oil I thought maybe it's low but it's not and hasn't moved since it was changed.

I have a 2004 Santa Fe (4 cyl 2.7 L FWD) with only 42,000 miles on it. Coming home from work I was stopped at a stop sign and after stepping on the gas (halfway thru the intersection) my engine stalled - coasting to a stop (while crossing a very busy intersection I might add). After putting it in park I try to restart it - the engine cranks over as usual and starts but roughly 4 to 7 seconds afterwards it stalls again. I did this 4 or 5 times again with the same results. I'm almost positive the check engine light is on. The next day I popped the hood to see if the belt broke but its fine so I tried to start it again (same results engine starts but after 4 to 7 sec. stalls again). Before this engine trouble I haven't had one ounce of trouble from my Santa Fe. Not to be funny but yes there is a half a tank of gas in it... with plenty of fluids in it. After some research I kind of think its the Crank-shaft sensor (seems to be a problem with them in the Santa Fe's).

I got an Error Code of U0D00. What this is or means. The scan tool says to refer to your manual but I don't have one.
What the vehicle is doing is that it will work fine for a while then when you stop (in park) the engine will rev really high and back down all by it self for example. It will go up to 3.5 and back to 1 rpm repeated. Then when you start moving the car it will continue to idle higher like you are pressing the gas. During all of this the check engine light will appear?

A few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?

What would cause and how to fix my Jetta. It will idle at almost 10 rpm sitting still? It also sputters as if trying to die. It has an after market air intake with a ktm air filter

Trying to get my daughters Santa Fe going. Engine stalling. Idles very slow. 2001 model with 2.4 engine, auto trans.
Code P0102 is active. Cleared with scan tool and it comes right back.
Replaced the MAF and no change.
Checked the intake for leaks / vacuum leaks and none found.
Checked for debris up-stream from MAF and all is clear.
Air filter is clean and dry.
Checked harness plug and found the pin 5 has 4.6 volts on it from PCM. This is the signal wire from MAF to PCM. 4.6 volts is KOEO.
IS THIS NORMAL OR IS PCM BAD ??? All other pins / voltages on harness plug are normal.

Have been noticing my 2003 SantaFe "coughing" on startup after sitting typically overnight or longer. Started noticing this after I went to Royal purple synthetic on an oil change. Started useing Mobil One synthetic and I am hearing the same thing. For a millisecond after I start it up after it has been sitting overnight or longer a quick "cough" kind of a sound that quickly goes away. No other problems apparent.
