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.
View 1 RepliesI 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.
View 2 RepliesI 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.
View 1 RepliesWe 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.
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.
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.
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.
View 11 RepliesA 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.
View 10 RepliesI'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 Replieswhat 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.
View 7 RepliesHere's the run down:
-bought 6 months ago for cheap because it wouldn't pass smog test
-changed Purge Control Valve (PCV) and it passed
-filled with gas, heard popping noises like a backfire, and coded it read the same "Bank 1 and Bank 2 running lean, like it did before the PCV and then also "Cylinder 3 Misfire" appeared.
-At this point the car started running rough, at idle, and through acceleration...sputtering uphill, and when climbing through the gears.
-Changed the plugs & wires
-NOW, it's cylinder 5 misfiring, and not nearly as bad. It's idling and running rough, acceleration has somewhat come back, but it's definitely not 100%.
Should I start with the PCV again, since it's not starting after I fill the tank, and climbing gears slow? Is there anything else I should be checking?
Recently 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.
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 RepliesI have a 2004 SF/2.4 I4. When the car warms up, the ignition coil sparks between the rubber boot and the coil itself, drawing the spark from the plug and resulting in a misfire. This is especially apparent when the A/C is running and the car is idle-ing, resulting in the A/C turning off and a rough jumping idle. Once the car is running this is not noticeable and the A/C turns on.
I have changed the spark plugs to new autolite plugs, and the situation disappeared for a day, but now it is back. I ordered OEM NGK Laser Iridium plugs, I hope they will fix the situation. Why would the A/C matter? Next on the list will be the ignition coil and wire change, but I hope to avoid that.
I have a 2003 Hyundai Sante Fe 2.7 v6. About 2 months ago I started the car and it was kind of a rough start. It usually starts right up. I was driving in the rain and when I would press the brakes the car would shudder like it wanted to turn off but the head lights and dash lights did not flicker. I had it towed to my mechanic. He found a broken vacum hose and replaced it. The car seemed fine.
Today it started up kinda rough and then would shudder and not accelerate no matter how hard I pressed on the gas pedal. It was also idling roughly.
I bought the car from a friend who was the first and only owner. She has ALL of the service records and took good care of it. It has about 120k miles on it. The spark plugs and battery are only about a year old. It has a half tank of gas. I checked all fluids, pulled a few plugs and they look fine too. Air filter is clean too.
I asked the previous owner if she had ever changed the fuel filter and she said she didn't think so. I reviewed the service records (assuming I have them all) and it doesn't look like it was ever done. I have run seafoam through it 3 times since I bought it last August. I change the oil regularly and rarely let the gas get below 1/4 tank.
2003 Santa Fe 3.6 V6 with ABS
The car sat virtually driven for a year before it was given to me. After 2 weeks of normal driving this past December, the power brakes completely went out. Had to drive the pedal to the floor to stop at even slow speeds. Took the mechanic and they replaced the Master Cylinder and both brake lines.
Shortly thereafter had an unrelated issue with a coilpack gone bad. Replaced coilpack and at that time replaced both sets of brake pads on the rear.
In January, started noticing grinding metal on metal from both front brakes. Took the mechanic and they replaced both calipers, rotors, and pads.
2 weeks or so later, after 10 minutes of driving the front brakes started dragging. The pedal would become extremely hard, and I could notice thew smell of the pads burning. Would have to pull over, put the car in park and pump the brakes to get the calipers to release. This would occur intermittently every few days. Pumping the brakes would always solve the problem.
Over time, the issue became worse, ocurring far more frequently. Around this time I noticed leaving the engine on in park while pumping the brakes would no longer solve the issue. I would have to completely turn the car off and pump the brakes to get them to release.
Started noticing around this same time that the left rear started grinding. The brake pads completely wore down in 3 months time. Too to the mechanic. Replaced caliper, rotor and pads.
Still having the same issue with the brakes dragging. One mechanic thought it could be ABS related and advised me to pull the fuse and the two breakers to diagnose. Still had the same issue, so put the fuse and breakers back in.
No mechanic seems to know what is going on with it, and I'd hate to have to replace all the brakes again as the problem goes untreated. Is it possible that the master cylinder or brake booster could be the issue? It's a brand new master but that doesn't necessarily mean anything, I'm told. Again, I can only get the brakes to release the pressure by pumping the pedal with the engine off.
Below is a link to a video showing what my 2003 Hyundai Elantra is doing. It is idling very rough (Jerks at idle) and can actually be heard in the exhaust. I think it may be miss firing?? Does not do it at speeds over 60. Under 60 it can be felt at times, but only at low RPMs. [URL] ....
View 16 RepliesI just replaced the crankshaft angle sensor, camshaft position sensor, starter and both serpentine belts (power steering and alternator, a/c belt). She fired right up, but now it won't sustain idle, she dies unless you keep the rpm at 1000. It almost seems like a fuel issue, but it's just a guess at this point. What to check next? Computer is throwing no codes at all.
View 4 RepliesHave a 2001 F150 FX4x4 and since the weather changed and started having days below 40 the truck has started running rough for about the first 15-20 miles. When you first start it starts like normal for first 3-5 min and then it starts loping real bad like it has a cam in it!
View 5 RepliesA couple weeks ago my 01 7.3 with 265,xxx started ideling rough and stalling. I had driven in all day Sunday and the next day it started out of the blue! It would barely start idle rough and stall out no CEL. I have singed changed the icp, fuel filter and I have checked oil level. Also used fuel cleaner. Still had no luck. When I changed the icp sensor the check engine light came on and was no change I then got a ford oem camshaft sensor and my truck fired right up but still sounded like it had a little miss here and there drove it for a few weeks fine now back to the same thing it will start up and idle fine for 10 seconds then start the rough idle but won't stall out anymore just idle rough. I am stumped I can't get any codes to pull up and if oriellys uses there scan tool while the truck was running it would shut the truck off! I can't find any answers.
