Question about 2004 Hyundai Santa Fe

1 Answer

Intermittent stalling when in park, rough idle

My 2004 Hyundai Santa Fe is having occassional stalling issues that doesn't produce any codes. So, of course, the dealership, can't find the isssue. Here's what happens. Right now, about once or twice a month, I will pull in somewhere and place my car in park. And what will happen is that the tachometer will jump up and down between 500 and 2000 RPMs. Then it will slowly drop towards zero until it finally stalls. Once in a while the car will almost stall out but then recover. Sometimes the car will start right back up and run fine for weeks until it does this again. Sometimes I have to try to start it many times or even wait about 30 minutes before it will start then it doesn't happen again for a few weeks. It's important to know that this only happens after I've been driving and then put the car in park. Also, the care will stay running and not stall if I keep my foot on the gas. So an issue with the fuel sending units has been ruled out. I have also at times heard like a large rush of air under the hood when the engine does try to prevent itself from stalling. It sounds like a big rush of air and then the car prevents itself from stalling out. Hope that made sense. Thanks for any help.

The AC unti is driven by a belt coming from the crankshaft. The belt is attached to the ac compressor which has a clutch unit that is suppose to let the compresser pully spin freely. by the sounds of your problem you might need a new pully/clutch for your ac compressor

This issue is caused by a fault in the evap. emmision system. In the engine compartment there is a purge valve that takes in engine vaccum and fuel vapours. The valve is malfunctioning. It is located on the right side of the intake planum.

P0320-is Ignition/Distributor engine speed input circuit. Inspect the wire harness and electrical plug ins in the area of the distributor. Replace the Ignition/Distributor engine speed sensor. This should clear up your Tachometer problem. Good Luck and happy new Year. From Ernie @ RedDeer, Alberta, Canada.

Did some research and found quite a few people with the same problem. All solutions were the same. Replace the Purge Control Valve, Hyundai part number 28910-22040. It is covered under warranty.

2009 Hyunda Santa Fe stalls while driving

I had a similar problem with my Santa Fe. It occurred intermittently but after I turned the steering wheel to the left. After much screwing around by the dealer and trying to baffle me with BS we heard about a strange solution. I am not a mechanic but the problem somehow related to a spring in the Airbag on the steering wheel. Changed the spring and "Stone the flame'n crows" problem solved. Never had a problem since.

I have a 2004 santa fe 3.5 l with 65,000 on it. recently it has been stalling and running rough, and the sometimes not restarting. i have an evap code.p0446. but no check engine light. started and ran ok...

Millions of people around the world, have all kinds
of problems, with all kinds of vehicles,at least once a year

That is a common EVAP Code for a Vent Control Valve
or circuit problem

Most likely the valve is letting in air under certain conditions
& leaning out your fuel mix,thus misfires & running rough

It is an unmonitored source of air entering the intake

If you can find it ,most likely under the rear of the car,
you could change that one valve

That is not the way to diagnose, but you may get away
this one time, if you want to chance saving money at
a repair shop. No guarrantee that is the isssue.

It seems Kai & Hyundia (asian vehicles) have a high rate of evap issues
vs; the big US three

My hyundai 2003 santa fe` wiper on both side doesn`t go down completely after that saturday the 19th blizzard. its stop about 30 degree.


Check to make sure the wiper arm nuts didn't come loose. If they did, you will have to take them off and reposition them. Before you do that, make sure the wiper switch is turned off , so that the wiper motor is in the park position.
