I changed the purge valve because it was hard to fill up. It idles fine but when I drive it at 40 and just cruise without a load on engine it starts to jerk or misfire. I'm going to change plugs even though they don't look bad and wires.
View 2 RepliesI somehow managed to kill my 04 Santa Fe 3.5 while doing the dreaded spark plug change and looking for pinpointing and rectifying the problem.
A quick rundown of the car... My mom bought her new in late 03, decided to get a BMW X3 a couple of years ago. I bought her with 65k miles. I just recently had the timing belt replaced by a reputable shop at 79k (yes I know I let it go too long.) I just hit 80k and decided it was also time to do the plugs as I had noticed a decrease in performance and gas mileage of late. Other than the recent dip in performance the car has been extremely reliable and has had no previous issues.
I researched as much as I could knowing that the 3.5 isn't the easiest engine to work on. I bought the recommended Champion plugs that came in the car from the factory as well as the oem Hyundai wires. I also replaced the plenum gasket.
I took my time replacing everything but despite my best efforts, I accidentally cracked the plastic on the radiator reaching over to the back bolts on the plenum. Other than that mishap, the only other issues was the #5 plug sticking which finally came loose after some begging and pleading to the car Gods. Unfortunately, my begging and pleading was enough for them to allow the car to start.
After reading a thread on here, I believe the problem is that I removed the TPS sensor to get to the bolts on the EGR valve, I know now that this was a big mistake. I checked and double checked every connector and can not find one that was missed or disconnected. The car would try to start but would not crank over. I was unable to get any OBD2 codes from my code scanner.
I decided to try a TB from a junkyard and swap it on to see if that was the issue. After swapping it on, the car started and ran like crap for about 15 seconds and stalled out. I was however able to pull some codes in this short time.
The codes I received are:
P0102: Mass Airflow Circuit Low Input.
P110 & P1172: ETS Improper Motor Current.
P1192: ETS Limp home - Target Follow Malfunction.
P2127: Throttle Pedal Position Sensor "E" Circuit. Accelerator Position Sensor 2 Voltage Too Low.
I'm not sure if these codes are left over from before I swapped out the TB or not. I reset the codes after I wrote them down and researched them to see if they reappeared but the car will not start again so I can't get the codes to reappear.
We have an '03 Santa Fe (2.4L). We are the original owners.
About 18 months ago, one of our Ignition Coils cracked and caused a misfire when then engine was under load. I replaced the coil, wires, and plugs myself at that time.
Since that time, we have experienced intermittent engine jerking while at highway speeds. There does not seem to be any pattern, and it does not happen every time we drive it.
I took it to the dealer who diagnosed a valve cover leak. They replaced the gasket, one ignition coil, wires and plugs. The problem still happened intermittently after that. I brought it back to the dealer, who diagnosed a valve guide/seat leak. Oil is getting into the cylinder and fouling the plug they say.
I could not afford the fix (and was very dissatisfied by the service I received) so the dealer recommended to change the plugs every 3 - 5K miles to get me through. I was told this on 03/31/09 (125695 miles). I replaced the plugs, wires, and BOTH coils again at that time.
Last week @ 130K miles the engine jerked again. I replaced all four plugs again Sunday morning, but the ones that I pulled were NOT look oil fouled. I showed them to a mechanic friend and the guy at the auto parts store. Both agreed that the spark plugs looked almost new. Sunday evening, while driving on the freeway, the car jerked again!
Since this happened again SO soon after changing the plugs, I really have a hard time believing the valve guide diagnosis. Some possibilities I have seen/heard:
- Crank position sensor or camshaft sensor (This was replaced at 78K miles along with the all of the belts)
- Clogged fuel filter
- Bad O2 sensor
- Vacuum leak from the hose that is between the throttle body and the engine casing
- The dealer's valve seat suggestion
This has happened a few times when the car jerks, check engine light comes on and seemingly goes into limp mode. Cannot engage 4 wd either. I leave the car for while then come back and the engine light is off and the car works normally.
View 2 RepliesWhile driving at between 20-45 MPH in warm weather only IDEAL SPEED IS 38-42 .. At times the car jerks forward and downward like, even slowing down at red light: Seems like the whole problem is coming from transmission! (Sensors)? The car is cursed. Example:
1- The symptom seems like your driving in drive position then all of sudden it shifts to low gear
2- When driving normal then it seems like the car shifts to neutral and the RPMs shoot up to 3-4
3- Sometimes when stopped the steering wheel shakes bad.
The car runs normal in winter time? Doesn't do it everyday.
2003 hyundai santa fe 2.4l ... When driving on highway speeds of 65 miles hour, I take foot of the accelerator and I put it back on to gain speed , it starts jerking or bagging. Also in the city when I press accelerator seems to have no power. I have no codes or check engine light on, what could it be?
View 2 RepliesI have a 2003 Santa Fe 2.4L (automatic) with 200,000 miles. Auto shop is recommending I change my transmission fluid. I've heard that changing the transmission fluid on a high-mileage vehicle is potentially dangerous. I haven't noticed any symptoms of "bad" transmission fluid.
View 5 RepliesI made a mistake, detached TPS from throttle, thought it was purge valve, then I put it back and today my car won't change gears, I messed something up, never had problems with my transmission. Santa fe 2003 3.5 ....
View 2 Replies2004 Santa Fe, 2.7 L V6. The oil was changed approx 5-7k miles ago (not really sure as I bought it from someone else) and I just changed it today. There's a new knocking noise in the engine. I used normal castrol GTX oil, 5w-30.
I drove it about 20 miles and the noise is still being made, so it's not a circulation problem.
What is the interval when trans fluid gets changed? I need to take a trip....round trip will be about 4600 miles I probably have less than 1500 on the current fluid now.. and before that had changed it 2 other times within 1000 about 8 mo. apart just to rotate the fluid. I am planning to do it as soon as i get back.
View 8 RepliesI've had the plug wire for my #4 cylinder burn out twice in the last 6 months. The car started running like crap and threw a CEL, the code was for a number #4 cylinder misfire. When I pulled the wire it has obvious signs of being burned out, like white powder and burn spots near the base of the wire where it goes over the plug. The plug and coil both look normal. No issues with the other cylinders. What could cause it?
This is on my '05 Santa Fe, 2.7l, FWD auto, with 180k miles
I have a 2001 2.7 v6 automatic it has started to struggle up hill to change gear.... and has no power ... it Rev's over 4000 before it changes out of second but fine sometimes after that .. i have had a terra clean done and no fault show on any diagnostic thing.
View 3 RepliesIts been getting quite cold here lately at night and in the morning when i go to the santa fe it makes a ticking noise for about 2-3 seconds and everything is fine again. I was thinking of dropping a quart of transmission fluid in the crankcase run it for a bit and change the oil?
View 14 RepliesI want to change the glow-plugs on my 2004 Santa Fe CRDI to see if it cures its rough/smokey start up, but I am not sure of their location. I think they might be under the intercooler, but I don't want to strip it all down to find out they are not there.
View 8 RepliesI have a 2012 Hyundai Santa Fe Gls. I noticed that the car jerks while driving. It stumbles when you slow down. The vehicles feels like it lags power like something is holding it back. I noticed that the gas mileage is bad. What's wrong with it? Is it something fuel related?
View 32 RepliesMy 2012 Santa Fe GLS 2.4L jerks and bucks while coasting. When you let go of the gas pedal the car would jerk. Is that normal for the car. The dealer could not duplicate the problem.
View 10 RepliesPurchased this car new. 2008 GLS w/ V6 2.7L engine. Wife's car, so I rarely drive it. She's complained for a month about an intermittent issue with the jar "jerking", usually during slow speeds.
I felt it for the first time myself. Was halfway through a pretty tight curve at around 20 MPH, starting to slowly accelerate when I felt a definitive lurch. might have been momentary loss of acceleration, or transmission. Not sure which. No CEL thrown.
I did see another thread mentioning a 2007 with a similar issue, but that person had codes thrown that pointed to a Throttle position sensor and a need to reflash a transmission. Think I'm seeing the same situation, or would this be different ? Absent any CEL, I'm sure the dealer will not be able to find it....
I bought a 2010 Hyundai Santa Fe 3.5L and noticed the engine would jerk really bad. It felt like the engine was going to jump out of the vehicle. I notice it does it when I turn it on in the morning and when I am driving slowly out my lane way the engine jerks. I have dealt with this problem since last year and they have already replaced the transmission which has done nothing. I took it back to the dealership and the service manager told me that he has already had 4 of the same vehicles come in with the same problem and they realized that they had to re-set the computer in the engine so that the transmission computer and the engine computer are on the same page that they talk to each other so to speak. Since they re-set the computer we have had the vehicle back a week today and this morning the car jerked again. I am tired of constantly taking this vehicle in and being told they have a solution and then it is not fixed. How am I supposed to sell a vehicle to someone when it feels like you are being lifted out of your seat because of the JERKING!!!!!
View 14 RepliesI want to change spark plug, took connector of spark unit and took bolt M6 out, lifted spark unit but not enough clearance to remove the unit in order to use wrench for unscrewing spark plug. How it works?
View 14 RepliesMy 2007 Sante Fe had problem this week. Took 6 attempts to start engine, then ran smoothly the rest of the night. The check engine light came on while trying to start vehicle.
Next day I changed the spark plugs but now find that the vehicle jerks when idling. Runs fine when going but jerks and bucks at stop lights and stop signs. Just added fuel injection cleaner to see if that may support the situation.
Engine light has come back on again since resetting. I have read several suggestions on internet regarding leak in vacuum line, Coil Pack damage due to faulty hose, even faulty 02 sensor.
My wife called me from the dealer and they said they wanted to change the spark plugs at 40,000 mi.??? Is this really necessary?
My M5 recommended interval was 50,000 Miles Seems really low to me Regardless of what the manual says any either way?
