Santa FE SM (2001-06) :: Changed Alternator - Car Bucking And Popping
I just changed the alternator in my 02 2.7l and now it is acting like it's not charging the battery. It's bucking and popping like before I changed it. I had to jump the battery and it drove fine for a while then I lost all power and no dash lights or anything. All the warning lights came on also. The headlights were dim and the car was bogging and bucking. I checked the ground and the battery is about 2 years old. Tomorrow I am going to get the battery checked and scan for codes. I also just replaced the starter a month ago. What could be the cause of this?

So me wife has put on about 7000 miles on her new tdi. It's a dsg, 2012. We brought it in for some warranty work and oil change at 600miles.
She is having bucking forward and back issues in the morning and after the car has sat for a while. When you go to accelerate light throttle it literally jerks forward and back and moves you in your chair when shifting first to second.
Dealer said no codes no updates nothing. I know the dsg is clunky normally but it literally jerks us back and forth in the seat 2 to 3 times or more.
Also when on the highway it surges up and down when cruising 70 to 75 like wind is blowing the car with steady throttle.
I told dealer last visit to reset the dsg gearbox as my wife did 70%traffic driving the first 4000miles. Now it's 90% highway.
Ford Super Duty (1999-2016) :: 2001 F350 Manual Trans 4x4 - Temp Gauge Not Working
I replaced the sensor on top of the water pump and the gauge still doesn't work. I tested the gauge by unplugging and grounding out the wire and the gauge goes all the way up. What I can try next. I didn't get a Motorcraft sensor so I'm going to go get one of those tomorrow hoping the duralast wasn't correct even though it looked 98 percent identical to the original. 7.3 lite diesel.

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 RepliesBMW - 535 :: Acts As If Engine Is Starved Of Gas / Bucking / Surging And Backfiring Sometimes
1987 BMW 535is ... I first noticed the issue after getting gas with the tank nearly empty. Car lost power under acceleration, bucked, stalled, etc. After it idled a while, I was able to get it home. Fiddled with it off and on for months to no avail. Because it sat for periods of time, I would need to jump it. On those occasions, it idled perfectly and ran like a champ. Upon restart, the poor running conditions returned.
I finally gave up and took it to a BMW shop, which replaced the mass air flow meter, plugs and rotor. It ran like new for a few months, but the bogging problem returned.
Essentially, it acts as if the engine is starved of gas, bucking and surging, backfiring sometimes. It does seem to run better on a full tank, but that isn't always consistent. It also seems sometimes to improve once the engine is warm - on occasion you can feel the transmission grab hold upon letting up on the gas and the problem totally disappears. But not even that is consistent, and lately it starts and idles ok but then starts coughing and shuddering unless you hit the throttle.
I have suspected a weird electrical glitch, but grounds are fine and everything else checks out. Usual switches and sensors appear fine. While it had been running very rich before the MAF replacement, computer now shows 21 MPG, which is very high for this car and certainly doesn't suggest rich running. Have not had the fuel pump/filter checked, but it seems to be getting gas, compression is good and the BMW shop did not suspect a fuel delivery issue.
Santa FE SM (2001-06) :: 2003 V6 Engine Chugging And Bucking / Belt Slipping Whine
MY 2003 Santa Fe is fwd with the 3.5 v6. While under normal conditions, the engine lost power and began "chugging" and "bucking". There was also a belt slipping "whine" associated with this problem. The problem continued for about two minutes, then corrected itself, and I was able to drive normally.
View 1 RepliesSanta FE SM (2001-06) :: Idling High And Started Surging
2002 santafe 4x4 v6. about week earlier I had a cel for temp sensor voltage high. so I replaced it. then... my power steering cooling loop by radiator started to leak from corrosion and for some reason my coolant gauge was reading about a needle with from the red. (maybe from getting ps fluid on it? idk) so I went to investigate why it was leaking and I thought the cooling loop pluged into a cooler on radiator so I removed my lower front engine mound and motor mount by the timing belt so I could raise engine up a2" to get a better look. when I saw it was just a loop and that was my leak I ordered replacement. It came in I swapped it out. Pretty easy . Decided to do a radiator flush and replace thermostat. Why I was at it. I drained radiator and took the old thermostat out. was gonna leave it out for the flush to cycle better. When I started it up it was idling around 4k rpms. I figured it might be because of thermostat so I put the new one in.
Started it up and same thing.... I check all the vac lines I could find all were tight. I unplugged them one at a time at throttle body/intake tube and blocked it off with my finger and it was still idling high. It also started surging. going from 2k to 4k and going back and forth. I checked the maf and it was clean as a whistle. No leaks on intake pipe. If I put my hand over maf it sucks the tube towards the throttle body. no air leaks anywhere. Took off iac valve its clean. I plugged the holes where it is on tb and started it up and no change in what its doing. also the throttle body flap is closed the hole time. Iac seems to be properly opening and closing. when I watched it after I unbolted it. I sprayed brake cleaner all over manifold to check for air leaks no change in high idle. I also took off the evap valve hose to tb and plugged it at tbody and no success.
I checked my sensor connectors and there tight and no wires are pulled out. I have yet to check cam sensor connection. (does it have a cam sensor?) I unplugged battery over night. this morning it ran at 2k rpm for two mins then surged to 4k. could it be my throttle position sensor? is there a way I can check with multi meter? Ive done a lot of research and it seems like a common problem with Hyundai but people don't leave a what fixed it post after they figure it out. they just leave the threads hanging. I hope I can figure this out.
When I get home tonight Ill plug where the brake booster vac line goes in. I looked at the hose and it was super tight and didn't seem to be leaking but maybe booster is idk. Ill also check wires to all 02 sensors. but if o2 sensor wire was broke wouldn't it throw a cel? Also no check engine light. but id did have an abs light come on the other day. was thinking maybe an abs sensor at the wheel but I am not sure. That light was on for a week before this issue started. It was never revving up until I started working on the other issues from my research I am guessing throttle position sensor. I am going to multimeter it tonight.
Bmw - 325 :: Occasional Surging Idle / Engine Will Rev Between 500 And 1000 RPMs
My 2001 BMW 325Ci has an occasional "surging" idle problem. When coming to a stop or at idle, the engine will rev between 500 and 1000 rpm's. Sometimes it will correct the problem and idle normally, or keeps surging until it eventually stalls. When restarted it works fine. Tried fuel injector treatment, fuel stabilizer treatment, and replaced thermostat. Still surges about 50% of the time. Had it to a dealer, and computer says its running fine.
View 1 RepliesSanta FE SM (2001-06) :: Surging Upon Startup And High Idle RPMS - TPS Replaced
2004 Santa Fe .... 2.7 6 Cyl 4WD 150k miles
Recently I started experiencing RPMs surging upon startup and driving before my engine warms up. The problem has gotten worse to where I push on the accelerator the RPMs jump to 2700 and the transmission feels like it disengages. My initial thought was the tranny was going bad and slipping. I checked the fluid level in the T and found it was maybe a half Qt. low. I topped it off, but this had no impact on the problem. On a side note, I am able to use the manual shifting feature on the "His and Hers" Shifter and drive the vehicle without any issue. Transmission works fine in manual. The surging RPMs which only occur in Automatic mode, triggered the CEL and I got a code of P0123 which is high side voltage on the Throttle Position Sensor. I replaced the gray TPS with a new black one.
Upon startup the RPMS jumped to 3000 just sitting in Park. I disassembled and reinstalled figuring I had something bound in the throttle. After reassembly the idle went up to 2200, still no good! I reinstalled the original gray TPS and the RPMs, upon starting, RPMs were 1500 with the old sensor...still too high. I did reset the ECU twice during the process of putting in the new sensor and reinstalling the old sensor. Right now I found that when I disconnect the TPS electrical connector, the engine runs normal. It starts right up with the TPS totally disconnected and idles at 750 RPMs! It will not shift to 2nd gear though, when I try to drive it in Automatic Mode. I can however drive in Manual Mode and drive normal and shift right through the gears. Who needs automatic mode right?!!!
Ford F-150 (2004-2008) :: 2005 - Occasional Bucking / Shuddering When Slow Down From Highway Speed To About 30mph
I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.
I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.
So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?
Santa FE SM (2001-06) :: Engine Won't Detach From Manual Tranny
I'm trying to remove the engine out of my 2001 Santa Fe, 4 cyl, manual tranny. Removal is to be done by lifting the engine upwards with a hoist, as I have seen in other postings. Already removed cylinder head and all of the peripherals and removed all engine-to-tranny bolts and the passenger side engine mount. However, the engine will not detach from the tranny. I does pry out to where I can see the teeth of the flywheel, but "springs" back into place when the prying ceases. I rotated the flywheel a full revolution in order to look for bolts through the inspection window at the bottom, but I see no bolts. It feels as if the splined shaft is seized against the clutch or something.

View 3 RepliesSanta FE SM (2001-06) :: Hard To Shift Gears (Manual Transmission)
I have a 2004 manual transmission Santa Fe. I've maintained it very well since new.
About 6 months ago I noticed it was getting difficult to manually shift gears. It wasn't grinding or anything, just "hard" to get it to go into the various gears while driving. Before, I could shift into any gear with just 2 fingers on the gearshift and it was smooth as silk.
I went in and had the gear oil changed. This was something I didn't even know needed to be changed and the guy said most people never do. They showed me the oil they took out and it looked more like black water than oil and smelled kinda funky. They changed the gear oil out, but still no difference, and in fact it's getting worse.
The best way to describe it is the only way I can really shift gears now is to find that "sweet spot speed" where the gears will change on their own (so to speak). I find it particularly difficult going from 1st to 2nd, such as when starting from a stop light. People almost rear-end me now as it takes me longer to get it into 2nd gear.
Once in gear it runs perfectly, no problems. The clutch seems to be working normally, except perhaps while stopped in 1st gear, it sometime seems to jerk a bit, and I find this most noticeable if I'm stuck in very slow moving heavy traffic with the constant stopping and then moving forward slightly and such.
It is almost impossible to "gear down" into a lower gear unless I'm at the speed where it would normally go into that lower gear on it's own. The best way to describe it is how it is possible to drive a standard transmission car WITHOUT a clutch if you shift at just the right time/speed. But I DO use my clutch, but if I'm not close to "that speed" it's really, really difficult to force it into another gear, and the few times I do try and force it, I'll often get a bit of grinding.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Occasional Miss At Highway Speeds / Bucking And Jerking During Even Gentle Acceleration
165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.
Santa FE SM (2001-06) :: Trans Fluid Change Interval
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 RepliesSanta FE SM (2001-06) :: Hard Downshift From 2nd To 1st After Warmed Up (Automatic Trans)
Recently started experiencing a hard downshift after driving for 30 minutes, and only from 2nd to 1st. No other shift issues with other gears, up or down.
When moving over to manual shifting, it doesn't appear to have the issue when downshifting in manual.
I replaced the radiator about 2 weeks ago due to a serious leak, and the shifting problem wasn't an issue before as I would have noticed.
Going to start with the fluid lvl, but it feels odds with it occurring during the downshift to 1st.

I have a 2004 Hyundai Santa Fe, has 99,000 miles 3.5L. After changing the alternator (alternator did die and drained my battery, the shop recharged the battery) now it seems be stuck in 3rd gear and does not wont to shift (it is a automatic). Fluids are good, transmission was flushed between 50-60,000 miles.

Have a 2009, 2500HD 4X4 23K miles that has an occaisional/intermittant trans slip when shifting from 2nd to 3rd (I think). It always seems to catch me by surprise so it may be 2-3 or 3rd to 4th. Shift point seems to be around 1800rpm, engine revs to about 2500 during the slip. It's always shortly after starting up and the trans is not necessarily up to full operating temp. I've noticed it happening in the dead of summer as well as the dead of winter.

I just purchased a 2000 f150 4x4 with a 5.4 automatic... it ran great for a few days and even ran fine on the 100+mile trip home from the previous owners house. All the sudden it shut down on the highway today. I could barely get it started again and when it did start, it ran like hell, bucking and jolting, almost like a really bad misfire. I could also smell trans fluid being heated up, so I let it sit awhile and then it fired right up. It drove for about a half mile and began to act up again. I threw it in second gear to limp it home which it died several times on. Each time I'd let it sit for like 15 minutes with the negative battery cable off. It fires right up after that but the problem quickly returns. Also the overdrive button doesn't work, and the trans control switch fuse (spot 29) blows repeatedly. Also the power door locks do not work.
