Santa FE SM (2001-06) :: 2003 2.7L - Rough Idle / Stalls After Short Warm Up
May 26, 2014
We are at 120K miles. The vehicle runs fine most of the time, but every once in 10-15 starts, it will rough idle or stall after a short warm up time when my wife stops at an intersection. Once she restarts it, it runs fine.
I have changed the spark plugs and wires, the fuel pump, the crankshaft position sensor (was fried) and after consulting this forum, I checked the fuel pressure regulator and the diaphragm is not leaking.
I was able to recreate the rough idle and the CEL on the dash, but my two OBDII readers said there were no codes And the bluetooth reader I am using is indicating that the following tests are not completing: Fuel System, Catalyst, Evaporative System and Oxygen Senors.
The dash CEL resets itself upon restart and does not light until the symptoms return.
After reading the Haynes Repair Manual, I am wondering about the Evaporative Emissions Control (EVAP) system? But I don't want to lead the troubleshooting.
We bought the vehicle at 60K miles and it has been mostly reliable.

I have a 2003 santa fe I just replaced the cat. in it because it was running so poorly. Now that I've replaced the cat it seems to be worse. The car idles real rough, and cant get it to go over 2000 rpms. No engine light. Had the codes checked and all came out fine. I pulled out the plugs and replaced with new. The car in park ran great until I put it in gear then went back to the same no power, rough idle and cant get more than 2000rpm with out a stall. Stalls but dose not die. Disconnected the pre o2 sensor no change.

Have a problem with my Santa Fe. 2004 2.4l.
My wife drove the car when the problem first appeared. She had been driving for 30 min, roughly 30km, and the car looses power and stops. Won't start when she tries. It cranks but won't fire up. When she waits for a minute it fires up but stalls.
We took it to a workshop. No code. They changed the fuel filter, which hadn't been changed for a long time.
They took it for a drive and it worked fine. I picked it up and it was working. Then it died when I exited the highway. It had lost some power during a second while still on the highway. I had driven it for roughly 30km and the engine was hot. Again, was able to start it it up for a couple of seconds if I let it cool for a couple of minutes. Got a lift home and returned in the evening and it started on the first try.
Took it to work the next morning. Wouldn't start in the afternoon when it had been standing in the sun and was gazing hot. Opened the fuel cap to release any vacuum. No change. Again started when I returned this morning and it wasn't very hot.
The engine warning lamp hasn't light up. Will try to see if there is a fault code tomorrow. Will try to measure the fuel pressure eventually.
The valve position sensor and timing belt was changed a year ago.

2003 Sante Fe is suddenly having a problem at stop lights or anytime the car is stopped with brakes. It feels as if the car is going to stall - or back fire. Very evident since it pulls on the brake pedal - just had back brakes replaced.

I have 130K miles on my Santa Fe. I just replaced the timing belt without the water pump being replaced. Picked it up from the mechanic and the check engine light was on and it was idling very rough. Left it there for him to recheck. He said maybe he didn't plug in the Cam Sensor all the way or at all. Next day he called me and said that the cam sensor was bad and he replaced it for free. Picked up the vehicle and the idle was a little rough but got worse on the ride home.

2001 windstar rough idle at warm up, start drive the van with cold engine for about 3-4 ml s, come to a light, stop, van starts rough idling, if I don't put it in neutral and hit the gas it will die ... after that , no problem .

Back after months...van has been checked by 2 ford dealer mechanics here in VA , nothing.
Now it's the opposite ...temp outside 90 or higher, drive it for 8 -10 ml, park and come back after 15 min. From shopping, try to start, won't idle, stalls every time I try , after 6-8 attempts, back to normal, all together 3 times, last time was so bad, had a real problem to make it back home, at every stop, it stalled.
Back to the shop ....they drove several times, no show ...it's fine, don't know what to do ????

2002 elantra hesitates and sometimes stalls staring from rest. Worse when cold but still sluggish after warm up. Where do I start?

I have a 01 vw bora 1.8t and recently I let it sit for one day and now it has trouble starting when it's cold and when it does start it has a very rough idle and often stalls out of you try and press the gas. Once it has warmed up she runs fine. My check engine light is on but I have no way to take her down to a shop to get the codes read. What is wrong with my car? One of my friends told me it could be a cool pack or a sensor.

This concerns a 2003 Hyundai Santa Fe 2.7L engine.
Bad rain, combined with a puddle splash caused a short (someplace). Vehicle ran poorly on way home and then eventually failed to start. Replaced the Cam Position Sensor and the Crankshaft Position Sensor. Checked all wiring and connections. Cleared codes and the vehicle started. Ran for about 15/20 minutes and a P0340 code popped with the engine light on. Car still runs fine. Researched code and learned that this code is a Camshaft Position Sensor A - Circuit Malfunction.
1. Bad ground in Circuit.
2. Open Circuit that fails to close.
3. PCM malfunction.
Questions:
1. Where in this vehicles is the PCM located? Is it within the main ECU in one of the other ECU fuses or an independent fuse?
2. Other than the 3 issues listed above, could I be overlooking anything else?

This is what my car is doing after it warms up. It will do it then stop, then do it again and so on. I am pretty sure when the motor is under load it runs a little rough but is hard to tell. The car has 178,000 miles on it. timing belt was done at 113,000. I just replace the plugs and wires changed the oil and the air filter 1,000 miles ago. and it will still do it. I am at a loss as to why it keeps doing this. I have tried injector cleaner, sea foam and engine restore. What would cause this? The check engine light is not on. i replaced the crankshaft positioning sensor about 40,000 miles ago.
Its a 2003 hatch with the 1.6 5 speed .....

Truck has a rough idle and finally just stalls out. I replace the under valve cover wiring harness and put in new glow plugs. With valve covers still off I started the truck in the issue still persist. I went ahead and unplugged each injector and each time the motor had a hick up .
What am I pulling apart and replacing next?

My 2001 Santa Fe is having some major issues with rough idling, and there is a fairly significant oil leak. The check engine light is not on. In the past year it has had a new fuel pump, fuel filter, valve gasket covers, spark plugs, spark plug cables, and transmission.

My wife and I own an 2003 2.7L Santa Fe 2WD with ~176K miles, for the past couple months we have been having several problems with this car, the biggest problem being that it will buck and jump while driving, and is now beginning to stall out. The stalling issue happens while driving at low speeds, while stopped in traffic, or while idling. The engine will rev slightly higher then stall out but will usually start right up afterwards. Only once that I know of, my wife has told me that it would not start right away.
I have read that the cause could be the CPS or fuel pressure regulator. Is there anyway, other than just swapping parts, to narrow down the culprit to the correct fix? The other problem we are having is the hard start after fueling up. I tested the Purge Valve by blowing into the hose, and determined it to be bad and will replacing it soon.
A little history on the car: I replaced the fuel pump and strainer last year, and a couple years we had 2 of the 3 catalytic converters fall apart and clogged the exhaust, so I knocked them out and have been driving with only one intact converter (rear exhaust manifold) since then. I know that isn't good for the O2 sensors, but we cannot afford to replace them at $300+ a piece.

At idle, (600 RPMs, might need to bring it up?) the motor is Real rough, but doesn't stall out, just very "wobbly" Once the car is brought up to the 900-1000 RPM range everything flattens out, and at driving speeds it drives great! Pulled up to 90 mph on the high way, and passed a few cars on some back roads and everything ran great, until I hit idle.
It threw a code for the Cam Position Sensor after I tried to restart the car, and the person who work on this car before me had zip tied the connector into the sensor because he had broken it. Low and behold, you cant buy just the replacement part of the harness.
I tried to get the wires all plugged back in, and the CEL went away, but the idle was still pretty rough. Also, at idle, the oil light flickers just a bit.

I just recently had a new (used) gas tank and new fuel lines (front to rear) put on the car.
On the first fill-up, I pulled out from the gas station, drove 20 seconds to the next red light. The car stalled (automatic transmission) when I came to a stop. It was hard to start and hard to keep going, and had intermittent periods of extreme power loss when I drove it down the highway.
Took it back to the shop, there was an engine code for the O2 Sensor, so the O2 was replaced, but made no difference. They checked fuel pressure and the catalytic converter, both were fine. They wanted me to keep driving it until another code came up.
As the tank neared empty, the car started driving almost perfectly. Filled it up again, and the problems started all over again. I have tried driving it with the gas cap off to make sure air can get in to replace the gas, but made no difference.
I changed the spark plugs, and all 4 of the old ones were covered in black carbon from the fuel running too rich (i assume).
Also, when the car is idling and it starts struggling, the exhaust does smell extremely strongly and is grey.
Now, engine code [P1166 O2S Controller Adaption Diagnosis Malfunction (bank 1)] is appearing (I have to check with the garage monday to see if it is the same code they had earlier).
I'm not sure why a new tank would cause this, unless somehow dirt/rust ended up where it didn't belong during the changeover.

I have a 2003 Hyundai Santa Fe. Within the last 2 months or so I have changed my timing belt, spark plugs, and all belts that needed to be changed. I notice that when I am idle at a traffic light, the car is a little rough or bumpy. Is this normal for its age, or should I be looking at something specific.

A few days ago, I started my wife's Santa Fe (106k miles) to warm it up and it had a rough idle. I gave it a test drive and the engine light came on and off a few times as it sputtered down the road. I retrieved the codes with my scan tool and it showed - P0300, P0304 and P0306. After some researching, I decided to change the coils, plugs and wires (under upper manifold) this coming weekend.
I have seen the web page instructions for doing this on a 2.7L [URL] .... but it has less stuff around the manifold compared to our Santa Fe. These instructions doesn't include coils was well since the plugs in front use just wires.
My question is.. Is there a set of instructions for the 3.5L for removing the manifold?.. From a less intense standpoint, maybe some of the hoses and cables can stay intact just to move the upper manifold or lift it to the side?... Also, Cyl 2, 4, 6 are the three sparks plugs in the front? 2004 Santa Fe 3.5l ....

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.

I'm having this cold start issue with my 2001 SF, but it doesn't seem to be fuel related like as the car starts fine but after about literally 1-2seconds the RPMs drop below 1k and the car will stall if I don't put my foot on the accelerator and keep it around 1000-2000 RPMs. But if I happen to make the revs go too high and let them drop again it seems like it wants to stall even easier. After about 30 seconds it smoothens out and drives almost perfectly except for a slight lack of power than normal going uphill (A.T drops to 2nd gear, sometimes 1st depending on the incline). We have had the coolant temp sensor and the fuel pressure sensor replaced. Could it be the MAF? We did clean it one time but it didn't seem to work much at all. Recently out of curiosity, I disconnected the MAF sensor and started the car it being started for a few days. No issue with idling whatsoever!.. ??

what would cause a pulsating rough idle when in park with the defrost or a/c on? when I turn it off or to any other position it's fine even when I turn if off it's fine as well? there is no Check Engine Light showing at this point.
