Every 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 RepliesMy 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.

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.
Occasionally, when restarting my 2003 Santa Fe V6,it refuses to idle. If I manually press on accelerator pedal it will start and run and after a few moments it will run fine. This seems to happen more often in high temps i.e., deserts.
View 5 RepliesI have a 2001 Elantra with 170K miles. well taken care of. I've been having a rough idle issue for some time now. The car idles very rough. I checked for codes and I got the cylinder 2 misfire code (P0302)...
I started out and replaced the plugs and wires, no solution...
I replaced the coil packs, no solution...
I replaced the MAP sensor, no solution...
I figured it may be no to low compression, so I did a compression test and all cylinders came back normal, still no solution...
I figured it might be a dirty injector, so I poured some seafoam in the gas tank, and no solution...
So my next step is to switch out the injector. Is there anything I am overlooking?
Here's the big thing that is happening too... Everytime I fill up the gas tank, I turn the car on and it idles even rougher. Like if you talk while sitting in the car, you sound like Chevy Chase when he is on the vibrating bed with Beverly D'Angelo in the movie vacation! LOL. It slowly goes away after 10-15 minutes of driving. All this rough running engine ONLY happens at idle, otherwise it runs very smoothly.
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!.. ??
View 4 RepliesRecently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.
I have a 2006 Hyundai Sonata with a 2.4 liter 4-cylinder engine. After filling the gas tank, the car idles roughly, but accelerates and performs fine at higher speeds. The rough idle lasts about 5-10 miles and then goes away.
Six days ago, I changed the spark plugs and air filter. Four days ago, I filled up with gas (and had the same issue with the rough idle). This morning, I started the car and idled it for 2 minutes while I scraped ice off the windows. I drove the car about 5 minutes and the check engine light came on. I took it to Autozone and the code given was P2187, System too lean at idle bank #1. "
Autozone suggested that it could be an air intake fault (MAF sensor), fuel pressure, or vacuum leak. They also said they have a MAF sensor cleaner to try. I am not sure if the rough idle after fill-up and check engine are related. Also, I don't know if the spark plugs or air filter could be related to the check engine. I was planning on making some easier checks first such as hoses near where I worked last weekend, especially near the air filter. Cleaning the MAF sensor is easy too. I was also going to check for vacuum leaks (incl. intake manifold) and recheck the spark plugs.
I am trying to fix the pesky hard start that I have. My car doesn't start right up anymore unless it is frozen cold. Other than that it takes 2-3 cranks sometimes 4 to turn over. That's annoying and embarrassing and I am trying to remedy it ASAP.
I have a check valve and Purge valve on hand right now. In my research it seems this is where I need to focus. I do have an engine code it was P0456 this time. I also have a gas cap.
I have a check valve because of the all too familiar cutting off early at fuel pump problem. I wanted to start there first since I am sure something needs repairing down by the fuel tank and since the problem is common. And hopefully the valve will work with the fill up and MAYBE with the start, if not that is where the purge valve comes in.
I got as far as get the 2 12mm bolts off and then couldn't make it any further.
I have an issue with my 2004 2.7 Santa Fe. I keep getting fault codes P0335 and P1372, the engine then goes into limp mode and is very hard to start.
So far I have replaced the crankshaft position sensor, the MAF sensor, the spark plugs, new ignition coils and leads.
I have traced the wiring and found no shorts, the only thing which does not match the service manual is that I get 5v on the CKPS sensor wire when the ignition is on, it said it should be 0V.
The car can sometimes run for 50+miles with no issues - then stalls with codes P0335 and P1372. I have a feeling its worse when the aircon is on but cant be 100% certain/
1997 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.
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 Replies3.5L 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 RepliesJust bought a 2004 3.5 v6 Santa Fe 140k miles. It's my first 21st century vehicle, the first time I've had one so computerized and all that. I'm really unfamiliar with many of the sounds it makes and what not. This runs nothing like my old Camaro or Dodge, what's normal or not.
She really seems to rev pretty hard in idle, especially when braked at a light while still in drive. Is this normal for a Santa Fe?
My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.
View 14 RepliesMy 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.
View 2 RepliesAt 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.
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.

Transmission has a hard time going into 1st and reverse. Also some times hits hard going into third. I have a CEL for a vehicle speed sensor? Was wondering if it's not the VSS but maybe one of the other tranny sensors?
Separate question. Same car has a rough idle issue. Occasionally stalls but intermittently runs normal always has a low idle around 600 rpm. I have a code for an injector on cylinder three.
VSS code : P0725 - engine speed sensor circuit malfunction
Injector code : P0203 - injector circuit open cyl 3
I Have a 93 bronco with a5.8 the truck will start up and run fine for a while and then the engine gets really ruff starts back firing and shuts off it only starts with starting fluid or after it sits for about 30 mins.
