View 2 RepliesHyundai - Tiburon :: 2001 Won't Accelerate With AC On?
I drive a manual 2001 Hyundai Tiburon. I tried to take it on the expressway today and it took a long time for the RPMs to get high enough that I could shift gears. It seems to want to hover at about 2000. When I finally got into 5th gear, it would only go about 50-55mph with the pedal to the floor. When I turned off the AC, though, it would go about 70mph, but it lost speed quickly on hills and took a long time to regain it. I am not sure, but it seems like the gas mileage was substantially worse than it normally is. I didn't notice any new noises or smells or shakes or anything like that. The car is just really lagging and my mechanic is closed for the night. I would like to at least have a guess what it is so I don't have to worry about it all night.

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.

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
Santa FE SM (2001-06) :: Jerks Forward And Downward While Driving At Between 20 - 45 MPH
While 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.
Santa FE SM (2001-06) :: 2003 - Jerks Occasionally When Try To Gain Speed
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 RepliesSanta Fe (CM - 2007-12) :: Stiff Brake Pedal / Hard To Accelerate And Speed Drops Fast Without Gas
This happens to me again on a very hot day. The symptom is: all of sudden, the brake pedal becomes stiff. I mean I can only depress down the pedal just a little bit. Then when I want to accelerate, the engine works very hard and speed picks up very slowly. RPM will shoot to 3000. When I remove my foot from the gas pedal, the speed drops very fast. The car slows down much sooner than usual. So my feeling is the brake is dragging the car. The dealer cannot duplicate the problem during short test drive. So what can be wrong? The brake booster was replaced a few months ago. Is it possible it provides too much boost?

Engine light (amber color) came on but went off a few days ago. Today I made a short trip and the light came on and then the car suddenly stalled. It did not die totally, but rather it seemed to be in a high idle and wouldn't rev up when I pushed on the gas. Letting off the brake the car would go about 20 mph but no acceleration, more like I'm coasting along oh so slowly.
Now I'm stuck at work with a 20 mile trip ahead of me. Is there some kind of trick to reset something to get it running again or am I stuck? What this could be? Won't be able to get the codes read until I can get it home, which hopefully won't involve a long tow.
Santa FE SM (2001-06) :: 2003 Hyundai Won't Start In Park
Two times in the last month my 2003 Sante Fe would not start - the radio, air conditioning would come on but nothing from the engine - not even a click - no check engine light. Had it towed both times - as soon as it was towed it would start up. It seems to happen in 2 week intervals. Now I realize bc they had it in neutral to get on the truck that is what facilitates it start. It hasn't happened in a week but I know it will again.

When I start it up it won't idle untill you give it gas to 2500 rpms and slowly let off the pedal to 1000 rpms to keep it running and itll stay running. When you turn it off you have to redo it all over again. The plugs and wires were replaced. It started doing it couple days after the back 3 plugs and wires were replaced. Just got the fuel pressure regulator replaced and it still wont start up without giving it gas.

I have an 01 Elantra Gls with perplexing issues. The car starts at 3000 rpms, and continues to bounce between 2k and 3.5k in both park and neutral. when I put it in reverse i get a very hard shift. It actually jerks the whole car. in drive and reverse, it idles around 1.5k it hesitates quite a bit to accelerate. All fluid levels are right and don't smell burnt. it takes me 10 mins to put 4 gallons of gas in. if i pump too fast it shoots back at me. i randomly smell gas while driving. Im hoping these problems are a couple of issue I can handle at home. i just wanted some input before i buy the manual. thinking vacuum lines maf sensor.

View 8 RepliesHyundai :: Jerks And Turns Off While On The Move
I own a Hyundai hatchback which i converted to a LPG sequential kit 6 months back. The car was running fine till a couple of weeks back. Now I experience jerking at 2nd and 3rd gear and sometimes the engine just turns off while on the move at these lower gears or if the car encounters a pothole(I then have to restart the engine ).
So far, I've changed the ignition coil(6 months back) and spark plugs(1 week back) but I still experience the problem.The Hyundai mechanic says that it could be a problem either with the wiring to the ECU( since soldering instead of couplers have been used) or with the injectors. He says the cord wires and ignition coils are just fine.
The Lovato authorized mechanic who fitted the LPG sequential kit says that it could be a problem with the spark plug cord wires or the ignition coil.
The reason I don't see a rationale with the Hyundai mechanic's argument is that the car has been running perfectly for 7 months. Initially , when the car was fitted with the LPG sequential kit, there was a slight jerking problem but was gone once I got the ignition coil replaced.
The reason I don't see a rationale with the LPG mechanic is that the ignition coil is just 6 months ( 4k kms ) old. I've been struggling with this problem for a while since each mechanic is giving his own version of the problem. I might be wrong in my rationale above.
Elantra XD (2001-06) :: Hesitate To Accelerate / Shift Hard And At Higher RPMs
So my girlfriend has an 04 elantra 2.0... the car will be running fine but then after so long of driving(maybe 15, 20mins) itll start acting strange..
It will hesitate to accelerate and shift hard and at higher rpms. Then at cruising speed it will turn off instantly(no sputter, hesitation, almost as if you just turned the key off). Seconds later the engine will come back but the gauges die and the engine will remain on.
At that point i pulled over and as i was on the brakes the car died when I came to a complete stop. Once the car completely turned off it would not start back up. However jump starting it got it going. The car is not throwing any codes.
Elantra XD (2001-06) :: Sputters While Idling And Power Loss If Try To Accelerate Hard
My 2004 Elantra occasionally won't start. When I hold the ignition on Start, the radio loses power (but the dashboard doesn't) and nothing else happens. Sometimes, tapping the gas pedal will suddenly cause the car to start. Once, I had to stomp the pedal to the floor before it would work.
I just replaced the battery (and positive cable end since it was corroded in place) and recently replaced the spark plugs (which were badly burnt). There is a check engine code for "catalyst underperforming" which seems unrelated.
I suspect my car has fuel delivery problems. It occasionally sputters while idling and often has power loss while driving if I try to accelerate hard. It seems to have trouble shifting into 4th gear from 3rd or 5th, but that may be another issue entirely.
What I should check to diagnose this, or replace to resolve it?
Santa FE SM (2001-06) :: 2004 Hyundai 2.7L - Loss Of Throttle At Random Times
I've been having trouble diagnosing a loss of throttle at seemingly random times. Sometimes while driving, especially after driving for more than 20 minutes or so, I will experience a hesitation while on the gas pedal as if I have taken my foot off the gas. It makes it impossible to drive until I pull over and unplug my TPS and then I can drive fine in manual mode. Then the next day I can plug my TPS back in, drive around fine for a bit before the hesitation happens again and then I have to unplug the TPS again and drive in manual mode. It doesn't make sense to me why it takes a bit for this hesitation to begin and why unplugging the TPS and driving in manual mode seems to fix the problem.
I've recently replaced my crankshaft position sensor, idle air control valve, purge control valve solenoid and TPS. When I recently placed the TPS, the hesitation problem and another problem I've been having recently, a high idle in park, seemed to be fixed, but then the hesitation problem popped up again. When I unplug the TPS, the hesitation disappears and I can drive fine but the high idle in park problem is back! I'm suspecting some sort of wiring problem to the TPS. I just went on a 100 mile camping trip in manual mode no problem, but I can't be driving around forever with no TPS.
Santa FE SM (2001-06) :: 2002 - Continuous Knocking Noise When Accelerate
I have a 2002 Santa Fe, 2.4, 2WD, stick shift with 125,000 miles on it. The problem started 9 months ago, when I was driving up-hill above 45 or 50 mph that continuous knocking noise came up from the rear-underneath the car, in order to stop it I had to reduce the speed, the problem has been there since then, but now is getting worse due to the noise comes up even driving on the street, when I'm gunning the car and shift to the next gear the noise comes up for 1 second, meanwhile I'm pressing the clutch pedal and then disappears, It's really weird because looks like it is related to the engine but the noise is in the rear.
I forgot to tell that the noise is not metallic, sounds like plastic or rubber, besides I already replaced the rear shock absorbers, inspected the exhaust to see any sign like touching the body of the car and checked all around the tires to see any sign of wear out and nothing, everything looks good.
