Elantra HD (2006-10) :: 2008 - Bad Gas Mileage And Skipping Gears
Mar 7, 2011
I have a 2008 Elantra with 50,000 miles. I know I was overdue on the tranny fluid change and the car was getting bad gas mileage and skipping gears. I brought it in and had the tranny flushed and refilled and now its running good. I thought it would be good to get a price on spark plugs because the book said replace at 60,000. I called the dealer and he basically told me he has not sold many of the plugs and they should last 100,000.
I seem to be getting conflicting info on what should and should not be done at the maintenance books written schedule. I looked for a price on Fuel Filter air filter which is in the maintenance to replace but again conflicting info stating that should not be changed unless there is a problem. Anyway, what should and should not be replaced at specified intervals? I know the tranny fluid change should have been done at 30,000 because it was very dirty and causing issues for me.

I have a 2006 f150 5.4l, and I have developed a problem. It seems the my truck has started to skip, or "pulsate" when I am accelerating. If I really get on the gas the "pulsate" goes away. This only seems to happen around 45-50 mph. Now this is where it gets weird. I have no check engine light on, and I have checked to make sure my light is working. I brought it to a garage and they told me something about Fords having a misfire issue that sometimes doesn't trigger a check engine light. . . . . now idk about that because every misfire I have seen triggers a check engine light, but I had them replace the spark plugs anyways. And it didn't fix my problem. At this point the only thing I can think of is possibly tranny.

I was having a discussion with a few friends and some think skipping gears when driving is bad and some say that its fine. For example going from 2nd to 4th and skipping 3rd gear. Which one is it?

I have a 2000 Alero w/ 2.4 103,000 miles auto. I have been trying to fix a problem for about 3 months. It all started one night when i got stuck in my backyard in about a foot if mud. I thought i could drive it out, but when the wheels would spin and traction control would limit the rpms. After getting out the car would skip every now and then going up an incline at highway speeds in 4th gear (drive) then it would skip while idling. I could get it to run smooth if i hit the pedal and made it shift to 3rd. I drive this car daily and the problem has got worse slowly. Now its hard to crank and when it does there is a small amount of white smoke with strong gas smell while the motor spudders for about 10 secs.
It will finally "clear" up and still misfire every few secs or just cut off. Gas mileage is terrible between 15-18mpg. The engine light and trac off light has only been on twice. Both times the code was for random misfire of multiple cylinders. I have put plugs, boots (wires), distributor, 2 fuel processor regulator, seafoam, all octanes of gas, pulled injectors (looked ok a little dirty but still could be one) and I have ordered ignition control module. Its getting hard to drive and even harder to sell. It has just started the white smoke and gas smell and i think its that's the pressure regulator, but the skipping and rough idle....

Is it ok/better/worse to skip gears while accelerating in a manual car? Example would be starting from a stop in 1st and going strait from 1st to 3rd gear. , I have a mazda 3 and i usually run 1st up to 3500 rpm or so and when i hit 3rd its around 1400 when I let the clutch out.

It's pretty cold these day where I live (about 2 weeks of -20C and lower). I know that winter can affect gas mileage but right now, I'm averaging about 13l/km (18mpg). I believe this is not normal.
I just bought the car and I noticed that the engine temp looks low to me (see pic attached). Is it supposed to run this cool? I also went to the garage and he checked with a obd2 scanner and nothing was wrong. Could a stuck thermostat be the cause of my poor gas mileage?

I have a 2009 Hyundai Elantra SE, and up until very recently I've had no issues with it, and am very happy with this car. About 2 weeks ago the malfunction indicator light came on. I checked the manual and it said to contact the dealer ASAP to have it checked out, but the car will still run. I've been terribly busy, and this is the first chance I've had to bring it in, so that's the plan for tomorrow. What this could mean, and will any necessary repairs be covered until the 100,000 mile warranty? If there is a repair needed that isn't covered, I definitely don't want to take it to the dealer!
Also, a few days after this light appeared, my gas mileage has been horrible, apparently. I say apparently because the digital mileage range now tops out at 255 when my tank is full; it used to be 336. It costs the same to fill it, and takes the same amount of gas, about 12 gallons. The gauge goes up to above the Full line, but I seem to go through gas so much quicker. Today for example, a trip that normally would cost me maybe $10 in gas, at the most, cost me almost $20. I haven't noticed any leaks, so perhaps this is related to the indicator light?

I recently bought a 2010 Hyundai Elantra GLS with about 40k on it. It was driving perfectly fine for about a week until the car would start jerking as the gears switched (I should note I switched the car out of ECO mode when I got it because I found it harder to accelerate with it on. The ECO mode keeps the transmission in higher gears to support fuel economy). I went to my shop and had the transmission fluid flushed and replaced. The car switches gears a lot better now, but another problem seemed to arise. About a mile or so after turning the car on and driving, it will switch into neutral for 3-5 seconds until I hit the gas hard enough for it to catch on and move. I've had multiple experienced people drive it around for awhile and they seem to find everything completely perfect with the car. Could it just be the way I drive, turning ECO mode off, or could something actually be wrong with the transmission or other parts?

My 2007 elantra has been rumbling when i change gears occasionally and sometimes when stopping at a stop sign the car just dies. The car starts right up though as if nothing happened. It only happens like twice a week but i really want it fixed. I already changed the motor mount next to the engine block on the left. Could it be the motor mount connecting to the transmission?

I bought a used 2008 Sonata GLS with 65K miles 2 years ago. It's been a great car so far. For the first 25K miles that I drove it, it had good pickup and got ~30 MPG for my highway driving. In the last ~5K miles, the fuel mileage has dropped to 25MPG highway and it has some hesitation when accelerating, especially on lower RPM's. I changed the spark plugs with NGK Iridium, but it is still having the issue. What to check?
Some possibilities: ignition coils, sensors, timing belt, etc?

So my car started skipping really badly about two weeks ago and sometimes even shuts off by itself. Now I've had two different mechanics try to fix this unsuccessfully. One replace the coil for two of the spark plugs and the wires for all four, didn't work. The other mechanic replaced the crank sensor, 15 minutes on the drive home from them, the skipping started again. Both mechanics found no issue driving it around right after replacing something, but the problem occurred after a day for each fix. Yesterday I put in some dry gas in the full tank, thinking it might be some bad gas or maybe I got some condensation, because the stalling didn't happen until recently when my mom filled up the gas tank completely.
Today I took the car for ride down to the end of my dead end road and the car stalled part way down, once I got to the end I put the car in park and then turned the car completely off then back on again. The car started fine and I drove back up to my house and parked in my driveway, I revved the engine in park and at around 3,000 rpm, it skipped once. I revved a few more times, but no skipping, I took it out for a ride and went about 10 miles with no skipping(but I kept the rpm under 3,000). Once i got back home I parked it and kept revving it for a few minutes even getting up to 4,000 rpm but still no skipping. I don't think the problem is fixed because both the first mechanic and the second had no issues with it right after they tried something, only for it to not have worked in the end. What it could be? This car has been my main mode of transportation so I need to get it working as fast as possible.

Just bought a new 2013 Elantra Limited. Love the car but........ very frustrated with the back suspension skipping around. Time to time my dad has to use the car but he is getting scared because the back skips around to much on the hwy ( same here). I know people are replacing the back shocks with the KYB and was wondering if i do change that would i be voiding the warranty the car only has 700 miles
Also one more thing i am getting 21mpg combined i know its still low miles and waiting to get it fully broken in but heard stories that it will not get better. If so whats the best bet to get that issue resolved. Car only has 700 miles ...

I just completed a successful second spark plug change, using Motorcraft SP515 plugs just like last time. After reconnecting battery and starting engine, it ran poorly throughout a short road test. Felt like it was skipping. Checked under the hood and found that the #2 fuel injector was disconnected, so I reconnected the injector.
I took another short road trip and it still ran poorly as if skipping. So, this time I disconnected the battery for several minutes while removing the #2 plug thinking I may possibly have fouled the plug by the injector not being connected. I also checked all of the other injector and coil connections. Reconnected battery and took another short trip. It still runs poorly. No codes yet.

My Azera has developed a misfire. Upon leaving work today it ran rough ass soon as I started it. CEL flashing.. I could feel it skipping as I was driving home. Skip never let up.
When I got home, I hooked up the Scanner to it. DTC P0300 was set. Which I think is random misfire. I checked underhood. Nothing appears amiss. With engine off I clear the code and restart the car, This time it set DTC P0301 cyl. #1. I think.
I do not have all the factory service manuals yet. so I need to know what the firing order is on the 2006 3.8 L VIN F Engine. And where the #1 cyl is located. I am suspecting a bad coil at the #1 Cylinder.

I bought a 2006 Certified used Prius a month ago and it was rear ended 2 weeks ago (uninsured motorist couldn't be more pissed) Well since the wreck the MFD screen has been skipping bars in the consumption category. It will just leave a whole space blank. Everything else it working fine. We took it to Toyota to figure out what was going on and they are saying that everything mechanical and electrical with the car is fine. They said the only thing they can think is that the MFD screen is having issues after the wreck.

I bought a gs 350 AWD about 3 weeks ago and I love it. But one thing I have been noticing is often but not every time from 0-20. I feel vibrations and almost like a skipping/jumping of the tires/car, its very soft. Is this normal?. I still have a dealer warranty of 30 days left. But its kind of far so I wanted to see what it was before I drove 2 hours to have them check it out. what this could be?

I have a 2010 Hyundai Sonata GLS that I purchased just over two years go. I have a couple of issues with it at the moment.
My first problem is I clipped my drivers side side-view mirror and a little plastic piece inside the side-view mirrror housing where the bolts go thru broke off. I checked with Hyundai and it seems like you can't purchase that plastic piece from them(they make you purchase the whole side view mirror). I also checked around at local junkyards but none of them had a 2010. What I can do here?
My second problem is when I'm slowing down to a stop and my speed gets around 10 mph or so the car jumps/jerks. It feels like it's almost skipping a gear or something and it's very noticeable. I was wondering if any of y'all have had that problem before and if so what did you do?

My wife just bought a 2008 Elantra. She says the AC was turning on and off on her way to work this morning. What to check?

I have a 2008 Elantra with 78k miles on it. Yesterday, to my dismay, I couldn't get any hot air out of my vent. I have never once had an issue with the hot or cold airflow before.
My coolant level is good and the temperature gauge is a-ok. The air coming in was cold yesterday and cool today; it appears it's just outdoor air temperature (as opposed to straight up cold) that I'm getting.
I believe my radiator is also overdue to get flushed...not sure whether or not that has anything to do w/this.
Is this likely the blend door actuator? I'm no car guy but I've been reading a little. Also....looks like this part might be 40-50. How much do you think I should be paying for labor if this is fixed?
