Santa FE SM (2001-06) :: 2004 - Brake Pedal Soft And Getting Lower

Soft Pedal. 2004 Santa Fe, front wheel drive 4cyl, 2.4l

When I first owned this Santa Fe the brake pedal was high and had lots of stopping power, over the last few years I noticed the pedal was getting lower. I have replaced everything needed thus far including pads, rotors and everything has recently been serviced front/rear/emergency brake/ calipers and still a soft pedal. Had the guys in our recon shop replace master cylinder and bleed the lines a few times with a full week in between bleeding to ensure there was no air in the lines. The mechanics are stumped but I'm wondering if we missed something...... I still can stop no problem but there is no grab in brakes until pedal is half way down to the floor or worse.

Santa FE SM (2001-06) :: Idles Rough After Battery Replacement

I replaced a dead battery in my '05 3.5 v6 Santa Fe. Other than the dead battery the car was running fine. After replacing battery, at idle, the RPMs drop below 500 and then go back up to over 1000 and then drops back down to 500-600. It has almost stalled a few times. At the low RPMs it diesels a little. When the RPMs spike the car surges and if I wasn't heavy on the brake, I'm sure I would have rear-ended the car in front of me. No check engine, no codes. Is this normal? I replaced the battery about 4 years ago and don't recall this behavior. If not normal, what is going on and where do I look? Its my wife's car and don't feel safe letting her drive it until this gets resolved.

Santa FE SM (2001-06) :: 2005 V6 Soft Brake Pedal

I have a 2005 Santa Fe 2.7 V6.

For over a month I have had a soft brake pedal. For those that may not know what that is, I push my brake pedal down 3/4 of the way, and I'll finally feel the brakes catch; however, I cannot stop quickly. I have had to use the Sports Mode to slow down my car many times.

I brought it to my local mechanic and he has done the following:

1) he thought it might have been the master cylinder, so he replaced it. he checked the old master cylinder and found nothing wrong.
2) bled the brake system a couple of times, but it still came back
3) brought my car to the local dealer to drain the ABS system. The problem still came back.

I waited over an hour as the dealership's service department checked out the car. Someone finally came to me and said they checked the lines and they are not leaking, so it has to be the master cylinder. I told the guy that it's a brand new cylinder, and when the mechanic looked at the old one, he said there was nothing wrong with it. All he could say was it's not the lines, it's the cylinder. If I had the problem before & after the master cylinder was replaced, & nothing was wrong with the original master cylinder, how is it the master cylinder?

I called my local mechanic on my way home from the dealership and told him what happened. He said he was going to do some research, mentioned something about replacing something with the ABS and he would call me today.

I searched the forums for brake issues and saw something about cracked ABS rings. Could that be an issue? Could it be something else?

Santa FE SM (2001-06) :: Brake Pedal Is Very Soft And Goes To The Floor Before Braking Occurs

Here's the short of it. 3rd time in a year the brakes on my 2005 SF (177K miles, 2.7L) have gone out.

The brake pedal is very soft and goes to the floor before braking occurs. Typical signs of a bad master cylinder.

The first time was a year ago. I bought a re-manufactured master cylinder, change it and bled the brakes. Worked like a champ and lasted 10 months.

To months ago same exact symptoms. I assume it was a bad re-man part. It's under warranty, not big deal. I do warranty exchange, bleed system, brakes return. All is good.

Less then 3 weeks later, brakes gone, same symptoms! This time I spend the difference and get a brand new OEM cylinder with reservoir. Replace, bleed, problem fixed. Brakes go out in less than a week.

I'm not leaking anywhere. Reservoir is to corect level. ABS light is NOT on. No chattering in brakes. Braking is smooth both when power brakes work and when not. No visible damage to calipers. I'm 99% sure there is no air in the system, but I'm going to try bleeding again. I have not put it up on a lift to yet to check all the lines.

Santa FE SM (2001-06) :: 2003 - Odd Noise From Brake Pedal In Stop And Go Traffic

I've been noticing an odd noise in the brake pedal in our '03 Santa Fe. I don't hear it all the time (almost never on the highway), but especially hear it in stop-and-go traffic. It's sort of a whirr, a "RRrrr". I've googled and watched YT videos and it's definitely not a hissing sound or a grinding sound, nor do I notice any difference in the brakes' responsiveness.

I'm apprehensive of taking it to the dealer for service because I only plan to have this vehicle for at most three more weeks. Have only held onto it this long because we couldn't afford to replace it until we sold our house-- which we've just done, and are about to move to a city about an hour away on 7/5. We'll trade in the car within a couple of weeks of moving.

The noise is definitely from the pedal and isn't anything like squeaking brake pads (I currently live in the DC metro area, so squeaky brakes become very familiar with all the stop-start traffic!). The videos I've found that point to a booster problem have a decided hiss, and it's not that either. Don't want to be unsafe in the time we've got left, but also don't want to throw another thousand bucks (every time something breaks in that darn thing, it always seems like it's about $800) into a car we won't have in a month's time.

Santa FE SM (2001-06) :: Brake Pedal Judders When Go Slow Round Corner

When I brake slow to stop or go slow round corner brake pedal judders with a brake judder noise I have read it could be cv axle or the ring tone or sensor cable.

I have replaced front discs and pads because I thought it was that but not then abs light came on and went back off and and one time stayed for awhile.

Mazda - Protege :: Very Rough Start / Idles Fine And Stalls As Soon As Touch The Pedal

1995 Mazda Protege1.5 LAuto153K miles.

My car was running fine, then one day it started sputtering while driving, mostly when I accelerated. It stalled and I could not get it started. This happened on a day when it was raining hard, but not sure that had anything to do with it. A few days later when I went to pick the car up it started right up, it had stopped raining and been dry for 2 days prior. But about a mile into the drive back home it stalled and I could not get it started.

Here is what I have tested so far.

- Put in new fuel filter.
- Tested the fuel pressure and pressure regulator
- Tested the injectors with a noid light.
- Tested that the spark plugs were producing a spark.

After I pulled the plugs and cleaned and dried them (they were wet with gas) the car started, but I think not because of anything really related to the plugs. What I've noticed is that when cranking the engine if I give it gas it will not start but if I keep off the throttle it will reluctantly start. But once it starts the idle is smooth and as it should be. Then if I give it any gas it immediately stalls. It seems to me given these symptoms that it is getting enough air to idle but not enough air to match the increased gas.

The only CEL code that I'm getting (which I had before this issue occurred) is the "closed throttle position switch" (I forget the number). If it was an MAF, or IAC, or EGR issue would I not get a code? What this could be and how to test it. Again my guess is its an air intake issue but not sure where.

Elantra XD (2001-06) :: 2004 - Brake Pedal Won't Depress

I've been having a randomly recurring problem with my 2004 Hyundai Elantra for several months now. I'll be driving along and will notice that my brake pedal won't depress. When I step off of the accelerator, it is like the brakes are already engaged. Eventually, the brake pedal won't depress at all and the car acts like the brakes are fully engaged. Sometimes I can let it sit for an hour or several hours and the brakes will readjust and I can move again. So far I have replaced both calipers, rotors, 2 brake hoses and the master cylinder, but I am still having this problem. My mechanic is flummoxed. Any time I have the car towed in, the brakes release by the time it arrives and he has no problem to observe.

Nissan - Sentra :: 1987 - Idles Real Rough At Times / Hesitates At Stop Signs / About Stalls Out When Press Gas Pedal To Go

I have a 1987 automatic Nissan Sentra XE- two barrel carburetor, mileage 212,880. The car has one major problem that is going to get me hit driving it in rush hour. Most mechanics will not touch the car due to being carburetor.

Let me explain: the car idles real rough at times, hesitates at stop signs and red lights, about stalls out on me when I press the gas pedal to go or when I start to make a left or right turn. However, other times the car has little to no hesitation and idles perfectly. I have not been able to come up with a good a pattern with this problem.

I have replaced, fuel pump & filter, spark plug wires, coil, distributor, ecu computer, ran sea foam through the fuel system and have replaced many vacuum hoses.

Santa Fe (CM - 2007-12) :: 2011 - V6 Idles Rough At Red Light / Stop Sign While In Drive

I have really taken care of this 2011 SF Limited with the 3.5 V6 but it has always seemed to idle rough at a red light/stop sign while in drive. Is this common for all the 3.5 V6 engines? I run a fuel cleaner through it before every syn oil change and also use top tier gas. It drives nice but like I said, at a stop in drive it seems to run rough at around 500-550 rpm's.

Santa FE SM (2001-06) :: 2004 - Rough Idle / Sputtered Down The Road

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 ....

Civic - Honda :: 2001 - Idles / Runs Rough At Certain Rpm?

Have a 2001 Civic DX, Manual Transmission, 228K miles. 1.7L SOHC.

Recently changed front motor mount and timing belt on the same day.

I noticed the car running rough and is only rough at certain RPM. Here are the rpm ranges it runs rough, 700rpm which is idle, 2200-2400rpm and 3400rpm approximately. It idles at 700rpm which I believe is the idle rpm on my car, so thinking my timing is not off. One more thing I noticed is if I have AC on and reving down in rpm it sounds like it is about to shutoff (never shuts off) and get a stronger vibration and same thing when I turn the AC on at idle. With ac on my rpm are 720rpm give and take a few. I been driving with above symptom for 300mi+ so far, even got it upto 95mph, don't know if it is an indication of anything. Got new spark plugs installed at 220K miles.

Could it be the motor mount or my harmonic balancer is out of balance. I did have to use 3/4" impact wrench to knock the harmonic balancer bolt loose. It is a little rusty given I got 228K miles on it.

I am just dreading the thought of my timing being off by a tooth, me and my friend checked the timing marks per oem manual, he checked the cam shaft pulley marks and I did the crankshaft. When we installed the timing belt I only turned the engine counter clockwise so I would not cause a problem with timing belt slack. My AC belt may be a little too tight as well.

The motor mount I put in was an aftermarket one that I bought from amazon. But I have put in aftermarket mount before on the same car and never had anything like this. I am planning to loosen the motor mount, shake the engine, tighten them back up and see if it makes a difference. May be the engine is not seated properly.

Santa FE SM (2001-06) :: Car Starts Up And Idles At Around 2,000 Rpms

This all started out when I wanted to change my original plugs that had 200k miles on them. I have that part done now and new wires. Then it wouldn't start without me starting it while holding the gas pedal down. Then I would have to press the pedal down or it would die.

I may need to clean the throttle body. I bought some Valvoline Throttle Body Cleaner and cleaned the throttle body it was black inside and now it's nice and clean. After that the car starts up fine except on the first try. It starts up and idles at around 2,000 rpms. When I press the brake it drops to 1,000, then back up to 2,000. The strangest part is I have no acceleration power now. I can press the pedal to the floor and it will only go to 3,000 rpms. It will slowly get faster as I drive but there's no immediate response when I press the pedal down.

Why would cleaning the throttle body do this? It throws a code when I first start it and it dies the P1110 code but I think that is because the rpms are at 600 when it catches it. No misfire codes or anything, so I think the plugs and wires are working. Just the faster than normal idle now and no power when I press the pedal down.

Would the throttle body cleaner hurt the throttle position sensor?

Golf IV / Jetta IV :: 2001 VR6 GTI - Idles On 3 Or 4 Cylinders / Runs Rough

2001 VR6 GTI....

Already done:

Replaced the coil pack and plugs

Measured resistance of plug wires (all at about 6K Ohm)

Replaced front O2 sensor

Replaced purge solenoid valve

Replaced coolant temp sensor

Replaced fuel filter

Replaced fuel pressure regulator

Replaced MAF sensor

Cleaned the throttle body

Cleaned the throttle position sensor

Ran a tank of seafoam treatment (injectors were new 6 mos ago.)

Checked running voltage of battery

It was smoking and stinking bad with a rich mixture. It improved with the MAF change but still runs like a farm tractor. Now it idles on 3 or 4 cylinders, runs rough through 3000 RPM then runs cleaner at above 3000 RPM, but only at light throttle. CEL is either on or flashing when driving.

Don't know what to do next - nice car not fun to drive like this. What this could be and how to test it?

Santa FE SM (2001-06) :: 2004 - Ignition Coil Sparks / Rough Jumping Idle

I 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.
