2004 Hyundai Santa Fe 3.5L for about a month has been sputtering/losing power when I come to a stop but keep it in gear. You can see the gauge drop when it sputter. Runs fine if I put it in park at the stop lights which I do because I feel as if may shut off (never has shut off). Replaced the crankshaft sensor and it had no effect. I so notice the same sputter when driving sometimes.
View 8 RepliesMy 2004 Santa Fe (4cyl) started sputtering and losing power, like it was about to stall out, then all of a sudden it'll regain power and drives fine. When the stuttering happens the check engine light comes on, but then when it regains power, the check engine light goes out. This seems to happen at highway speeds because I can't seem to recreate the issue driving around the neighborhood. I also can't scan for codes because I cannot get the CE light to come on (when I want it to). About 2 years ago I took it to the dealership for similar symptoms, with my car eventually stalling completely out and I couldn't get it to start back up. The problem then was crank shaft position sensor, which I had replaced.
View 2 RepliesI have a 2001 chevy venture (254,000 miles) that has me baffled. It has been a great van but it started about a month ago sputtering and bucking and numerous times shutting off. Most times the engine light would NOT come on. It would get the hiccoughs and start bucking like someone learning to drive a stick shift for the first time. Once it sputtered hard enough to throw off the serpentine belt. I put a new timing belt on it last year when I redone the intake manifold gasket. Now its not shutting off but it has only about half the power it should and the engine light is starting to come on more often.
It bogs down and then it will try to go then bog down again. The engine light blinks for about 20 seconds then stops and goes out. When the engine light is on and stays on the code most often says system too lean, and a egr flow insufficient. It does have a vacuum leak in the hose going to the egr. Have ordered that, hasn't come in yet. Gas mileage is horrible. I have done new plugs, fuel filter and cleaned the K&N air filter. Someone suggested the catalytic converter. I dumped in a bottle of 'Cata-cleanse' from Autozone. No difference. A friend of mine had a venture doing the exact same thing. It was in the shop for 6mo with no luck. But his straightened out on its own and is running good now. I really don't feel like waiting 6mo to see if this will straighten out.
2004 Hyundai Santa Fe 3.5L V6. I am experiencing an issue of losing power as I travel up an incline and it doesn't matter how much I depress the gas pedal. The codes that I am receiving are P0101, P0174, and P0171. After reviewing the codes and doing some research I'm thinking it is either the mass air flow sensor or the fuel pump, which can tend to fail in vehicles 10 yrs or older depending on vehicle mate Nance (i.e. constantly running the tank down to almost empty).
View 6 RepliesThis began occurring after I hosed down my engine with degreaser, stupid me. Car will begin to sputter like it is losing power around 30-40mph, and then it's fine. Rarely it happens around higher speeds with the cruise control on around 65 its just fine and the CEL never came on. Well yesterday i pulled the battery cable for 30 minutes to let things reset, then i got a CEL, code P0030 which I think is an o2 sensor, so i guess it went bad from the water perhaps? What part I need, where it is located and how difficult this would be to do in the driveway?
View 8 RepliesI have an 02 Santa Fe with the 2.7, 4x4. This started a few weeks ago. When it is first started, it cranks over for a few then starts, idles 1500-2000 rpm. It is a little hesitant at first, but will eventually run fine. If I go to the store after it is warmed up, shut it off, then go back to start it again after shopping, it does the cranking over for a few, and when it starts, you can smell gas (strong smell). when you go to take off, it hesitates real bad, backfire rumble through the exhaust, has no power, bucks, and you have to feather the throttle to keep it running. If you put your foot to the floor, it does nothing, 20 mph if your lucky. if you can keep it running long enough without it stalling, which it has done, and hit the highway, and get going, it will eventually work itself out and run ok again. There is NO CEL. It is getting worse.
View 1 RepliesI have a 2001 santa fe. replaced the battery, alternator and I keep losing power while driving, radio goes on and off, a/c blows on and off, doors lock and unlock by themselves it holds a charge for about a week then breaks down again!
View 5 RepliesI have a 2000 Ford Ranger, small v-6, automatic, no AC, windows, door locks, this has a heater and radio. This truck runs fine until I try to climb up the mountains (Colorado) and at app. fifty mph the engine starts sputtering and losing power. More than just an engine ping. When I run on flat ground while pulling a fifteen hundred pound load it runs fine with no sputtering or loss of power. Mechanics here are stumped.
View 8 Replies2004 Santa Fe 2.7L V6 2WD ... Car was running fine, filled it with gas, and upon starting, heard a backfire into the intake manifold. It coded for a Cylinder 3 misfire so I had plugs and wires changed.
Now...The car starts, idles rough, accelerates sluggishly, and running rough any time it was around 2000 RPM. After I changed the plugs, it started bucking a little and stalls when I take off in the morning.
Coded and it's reading 7 codes, but some are duplicates:
-P0274 Cylinder 5 Injector Control High
-P0305 Cylinder 5 Misfire
-P0102 MAF or VAF A Circuit Low Input
-P0050 H02S Bank 2 Sen 1 Heater Circuit
-P0030 HO2S Bank 1 Sen 1 Heater Circuit
-P0274 Cylinder 5 Injector Control High (Shows Twice)
-P0102 MAF or VAF A Circuit Low Input (Shows Twice)
After having a backfire and then cylinder misfire...replacing the plugs and wires.
We have a 2003 Sante Fe 2.7l that looks like the tranny is losing the clutches. Not ready to give up on it as the engine is still strong even with 176000 miles.
View 9 RepliesLong story short, I have a tire that is losing pressure. In two months it went from 30PSI to 10PSI. I caught the tire right before my trip to Vegas and filled it back up to 32PSI and today it was at 25PSI for a total of 22 days. I figure I am losing around .3PSI a day. Took it into Sams where I bought them and of course they couldn't find a thing wrong with them. Sprayed them with soap and water and dunked them in a trough but no bubbles. They weren't going to do anything, but I talked them into putting a new valve stem on and at least taking the tire off the rim and taking a look. I realize it could be a dynamic problem where it only leaks while the tire is rotating. Is there anything else that I'm not thinking about verses having a leaky rim?
View 3 Replies2003 Elantra gt 90,0000 miles manual transmission. Rough idle under 1000 rpm it smooths out completely above 1000 rpm.
Also the engine makes a ticking noise from a cold start up. It stops making the ticking noise after 1500rpm or when the engine warms up.
Occasionally the car has a sputtering backfire. This happens when I park the car after being on the highway.
Replaced the plugs, wires, and the pcv valve. Dropped the oil pan and it and the oil pump pick up screen were clean.
The only check engine light to come on was for the speed sensor. It has since gone out on it's own.
My father owns a 2003 Santa Fe GLS with the 2WD 2.7L V6 engine.
Recently it has been having lots of power loss issues. It vibrates/misses when idling, if you put your foot down on the gas pedal, whether under load or not, it sometimes stalls or just sits there. We took it to Hyundai, and they had no error codes. They charged us $150 to tell us nothing is wrong with it, when clearly something is. The car has become downright dangerous to drive because it cannot make it up hills without stalling/losing power.
The most recent thing we had done to it was the wires/spark plugs changed, which I think was at 65k on the odometer?
I have a 01 santa fe 2.7 motor. I have read several threads in here regarding the famous pump whine. my pump is making a whine at idle, I have cleaned the bottle and made sure the screen has not restrictions, drained all the fluid, and have inspected the lines for leaks.
With a stethoscope have pin the noised to the pump, the noise travels in the reservoir when I race the engine the noise is more evident on the bottle. I am tempted to replace the pump, but the steering has no issues and operates fine, also no change in the whine noise when moving left to right.
I was driving yesterday and my Toyota pickup started losing power. If I let off the gas at a stop it would rapidly die. I managed to get it home but had to floor it just to get it going in 1st and 2nd gear, and if it was in neutral it would die without giving it a lot of gas. The only way it will start is if I give it a lot of gas while turning the ignition, and have to keep the RPM's up to keep it running. Looked under the hood while it was running and when I let off the throttle the entire motor would shake violently. Cant tell if it's just not getting fuel correctly or if it blew a head gasket maybe. Seems like it might only be firing on 2 or 3 cylinders.
View 3 RepliesTruck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?
View 7 RepliesMy '05 Elantra GT has done some weird stuff in the last few days: Losing complete power for a second when pulling out of the driveway two days ago, flickering headlights constantly, complete loss of power while trying to start last night, then suddenly everything started right up. Today, it lost power 2 times in about 10 seconds while I was sitting at a light on the way to work, but the motor never shut all the way off so it just restarted. Today at lunch, I turned the key and everything went dark. I pressed the brake pedal, the dash clock came on and then I was able to start the car. Bad Diode in alternator?
View 2 RepliesI'm currently moving cross-country from LA to St. Louis. Had routine maintenance done b4 I left. I've only made it to New Mexico so far b/c my car is losing power after logging 250 mi. RPM's also become erratic. Doesn't completely stall, but won't let me go more than 45mi/h. After a rest break, the problem doesn't re-create.
At my first mechanic stop, the computer checked-out as ok. That mechanic changed the spark plugs and also told me the 2004 has no fuel filter (fuel filter being my suspicion of what was wrong).
Today it lost power again. Jim Bob at a rural garage said maybe the alternator or fuel pump. I have an appt. at Pep Boys tomorrow, as the dealers don't have any avail appts. until Fri.
The contents of my apt. are in the trunk and backseat. Is it worth it to remove them (to get to the fuel pump) at the cost of another hotel day, or should I limp home at 250 mi. a stretch?
I have a 2001 infiniti i30 automatic with about 118000 miles. The car runs and drives fine but every now and then while i am driving it and i push on gas the RPM will go up but the car will not move forward. I noticed that this usually happens when I drive the car a lot. If i turn it off and on it drives normal again. I have had 3 mechanics try to troubleshoot it one recommended to change the MAF which I did and the car ran fine for about 6 months and is starting to do it again. Service engine soon light is on again. What exactly is the issue that's causing it.

View 3 RepliesMy sister has a 2001 Prius w/ 150k miles. She asked me if I could shut off her check engine light. From what she tells me 1-2 times a year on very hot days (high 90s) when she starts the car it will stumble and stall (been happening since 03 when she got it).
I took it to autozone to get the codes which were:
P0300 - I assume all the misfire codes are from it stalling
P0301
P0302
P0303
P0304
P1636
P3002
Since she said it was normal for the car I just cleared the codes for her. She did have this checked out one time at a dealership when the car was under warranty and they found nothing wrong and blamed it on the weather.
I searched the forums for 1636 and 3002 codes the 12v battery seems like it could be a likely culprit (it is the original battery as far as she knows). A few weeks passed while I was researching the codes and the battery options and she had another problem. (still haven't ordered the battery yet)
She says the car loses engine power 1-2 times a week (she drive 4-500mi a week). The dash stays lit up and the power comes back quickly. Sometimes while accelerating it will just stop accelerating and then go back to normal, or on the highway it will slow down and then be back to normal. Check engine light is back on and the new codes are:
P0420
P1636
P3002
I'm going to get a new battery ordered today but I'm kind of skeptical that it has anything to do with this new problem.
