2007 Santa Fe 3.5 ... All of a sudden today the engine is vacillating and at idle shuts off. I have to keep my left foot on the brake pedal and the other on the right to keep it running without lurching forward. Does this sound like the throttle body?
View 1 RepliesEvery time i stop for gas..my 01 santa fe is hard to start..it would take 4 to 5 start before she goes, then i have to keep the rpm up, bring her to idle..after that shes ok, till the next fill up.. the only way around this is to keep her running while gassing up..while filling up she run rough idle, some time engine shuts off..then its hard to start..
View 5 RepliesWe've had this 2009 SE with the 3.3 since brand new, and have had the engine shut off/lose power out of the blue while driving 4 times over the years.
Each time we were able to pull off the road, shut off the ignition, then restart and have it work normally but the odd thing is that there hasn't been any codes or CEL on etc. so when we take it to the dealership they run diagnostics, and say "no codes, no problem" which is beyond frustrating.
How to get to the bottom of what's causing this?
My wife was complaining of the ESC light came on and off. Rough idle. Also has a check engine lite.
View 23 RepliesI have an 07 with the 3.3L and on start up the engine runs really rough and while driving when warm it keeps losing power with a regular rhythm. It almost feels like and injector or ign coil is dropping out. I have no CEL and have recently changed the spark plugs and rear upper O2 sensor.
View 5 RepliesWhile the car is at a full stop it idles at 500 rpm. I am assuming this is normal. But randomly the accelerator dips and the entire car jerks and feels like the engine is going to choke.
This started happening when the vehicle was at 10K miles and I took it to the dealer but the problem did not repeat itself there. They said they ran all sorts of diagnostics and came up with nothing. At this time the problem would occur may be a few times a week, while waiting at a red light, etc.
Now the vehicle is a 30K miles and it is happening more frequently. Several times a day.
I recorded a video of it to better explain the problem.
My radio completely shuts off in my Sante fe. But after several minutes it turns back on. Then off again, then on again.
View 3 RepliesWhen I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.
I have a 2008 Santa Fe 2,2 CRDi that recently started to behave bad. When cold it starts but runs only for a few seconds before it dies. The engine seems to shut off without any notice. I am able to start the car again straight away, but the same thing happens.
If I try to push the throttle I might be able to keep it running for a longer while, and it seems to improve as the engine gets warmer, but it still dies after a while. (Some minutes.) When running, the engine feels kind of rough (hard) and not a smooth as its supposed to be.
I have cleaned the EGR valve, and replaced all the injectors. I also checked the diesel filter for water and flow, but didn't replaced as it was changed this summer.
The car is a no runner as it is now, since the uncontrolled shutdown of the engine makes it danger to use in the traffic.
Trying to find any information on what's happening with my 2008 2.2 Diesel Santa Fe ... Been driving fine until I pulled up at a set of traffic lights yesterday and started hearing a loud rattle- knocking coming from the engine at idle.
Put it in gear and drove and it goes away. When at idle if you rev the car it goes away.
Mechanic seems to think it could be clutch as it vibrates the gearbox, but sound seems to be more prominent around the engine, my thoughts were maybe a loose timing tensioner.
Clutch replacement is very expensive.
3.5L v6 173k. Engine shut down twice while driving. Started right up each time. From what I have seen in the forum it could be the Crankshaft Position Sensor. If it is the CPS, should I have the timing belt done at the same time?
View 4 Replies1997 Subaru SVX (Alcyone) LSi, 3.3L H6 engine.
My SVX was driven from Denver to Las Vegas, NV and it developed an odd habit where the RPMs would start to oscillate while on cruise control. I had to disengage the cruise control to get the oscillations to stop. Three days later I was driving the SVX to work and the RPMs started oscillating at idle and the car started running rough and it died.
These things have all been replaced with OEM grade parts: Spark plugs, electric fuel pump & strainer & fuel filter, Mass Air Flow sensor, new air filter and fuses.
The car starts up fine but after a few seconds the RPMs begin to oscillate. Then the car tries to recover, the idle becomes rough, and the the RPMs drop very low and the engine shuts off.

When I start the truck, it idles rough, like it's idling too low, and even feels like it's missing during idle. Sometimes when I put it in gear (reverse or drive), it shuts off. No codes are being thrown. It has no problems driving around town or on the highway. It's just that initial start and idle.
I've checked all the following with a shop manual:
Ignition Control Mod.- Orig and 2nd one from junk yard. Both tested good at store. Even the testing in the shop manual with an ohm meter and battery tested good.
Ignition coil- tested good using shop manual testing
TPS- Scan shows .2-.7 at idle.
Plugs, wires, cap, and rotor are good.
Vacuum is good.
Haven't checked IAC, EGR
I recently moved cross country, and about halfway through, I broke down. Engine would turn over, fuel relay would click, injectors would work, but no fuel. Pulled it in to a truck shop, and after all my testing and theirs, we determined it was the fuel pump. After they had to fix a pinched hose, it ran. I made it to Texas. I didn't have the idle issues prior to the trip. Just had the tranny rebuilt and everything was great.
I thought, at first, the ignition control mod was the problem because it got a bit warm pulling the trailer, and I know those things don't like too much heat. No dice. So, what controls idle at Park and in gear but at idle? EGR, IAC?
I did a WinALDL scan. IAC at Park/Idle ranges from 18-55. The engine never runs in Open Loop. I would say the engine runs mostly rich according to the scan. I've attached a manageable version of the WinALDL data.
Also, I need to check the thermostat or temp sensor. Scan reads the engine never getting higher than 180.
PCV hose/grommet was rotted out with 1 inch hole but supposedly he spent a long time tracking down the problem. It was located way in the back middle (like underneath the wiper blades area).

What known issues would do this but not turn engine light on? Motor sounds excellent and runs excellent. Previously it was missing and engine code come up as random misfire, misfire cylinder #2 and #4. I replaced the coil packs on 2 and 4 and erased the code and there was a 1000% difference. Ran excellent (still does).
However, a week later I noticed a subtle shake in the motor, and at idle it would stay at 1...maybe slowly chirp just above 1, and then sputter a little down to 1/2 rpm. It will do this and stay running, but sometimes it will cut off.
What are the possible things that you think it could be considering no check engine codes? (Bad motor?)
I recently had a remote starter (AutoMate) installed in my 2008 LS460. The remote starter works great but when I open the car door the engine shuts off. I then need to restart by pressing the START button on the dashboard. Is this a safety issue or is this something that can be avoided?
View 8 RepliesI have a 1991 Mazda Miata. Recently I noticed the oil pressure gauge was vacillating wildly between 30 and 60, whereas it always stayed at 30 before. I checked the oil -- it was fine. I took it to my nearby mechanic who said it was the oil pressure gauge. He replaced it with a Miata part. Now the oil pressure stays at 60 once I'm over 20 mph. So what is the correct oil pressure setting and do I need to take it back to the mechanic?
View 5 RepliesI drive a 2006 Scion tC with 96000 mileage. The car has been getting a lot of problems lately.
1. P0741 torque converter engine light
2. Lost in power
3. Lost in MPG
4. Shakes a lot inside
5. Low Idle
6. engine shuts off on reverse and d mode
7. Noisy strange sounds
8. Gear slip around 2-3
9. RPM goes high at low speed.
I Replaced,Spark plugs, coil plugs, engine oil, coolant, steering fluid, brake fluid. I need to to replace the transmission fluid. I was told by a couple of shops to get a transmission rebuild....
I also read someones comment online: "It's your transmission. Your torque converter is bad. There is too much torque as a result. When your car is in neutral or park there is no torque being created. When you leave the in gear idle state, the torque is relieved. That is why the problem will go away when you hit the gas."
Vehicle: 2011 Santa Fe 3.5L AWD ... Oil light coming on when braking hard.
Anyway, my problem was my oil light coming on at idle. Initially, it happened to my wife and she called me about it, and I attributed it to the cold weather and thick oil maybe not pumping properly when the vehicle was cold. After driving it myself, I realized this only seems to happen AFTER the vehicle has warmed up to operating temps. Took it to the dealership, they told me it was a bad oil pressure switch, put in a new one and off I went. (Note: oil was also changed at the dealership when they put in the new oil pressure switch)
Here I am two days later with the same problem. Just about to work this morning and sure enough, the oil light came on again while stopped at a stoplight.
Attached a picture below of my dash...the light flickers and comes on when the idle drops. I've never taken notice before, but what is the actual idle speed of the 3.5L? When the light is on, mine is about 500 rpm...
Also, for those of you with a keen eye, note the distance travelled (238 kms) on my current tank of fuel. Cold weather + all short trips within city limits does not make for a happy Santa Fe.
As the weather is getting colder I noticing again my RPM's taking longer to drop down to 1200 or less. Upon startup the engine rev's to 2000 and drops in 2 sec quickly to around 1500 (all these are based on the crude gauge readings, not a digital tach).
I don't like high RPM cold starts in the first place and why its stays just around 1500 and lower for about 2 minutes before it lowers to around 1200RPM. I don't like engaging the transmission at those high RPM's. My other vehicles did nothing like this and the increased start RPM was down 1000 within a minute.
What sensor is having the computer run it like that and not let it drop faster. I doubt its the O2 sensor since its the same on a hot day just doesn't rev up to 2k but 1500 or so. Jabs at the gas pedal doesn't work it drop any sooner either.
I have a 2007 SF 2.7L V6 with 55000km.
Recently we have noticed that from a cold start the engine idles roughly few a short time and especially bad if put into gear only moments after starting.
Do we need to let it warm up for longer?
