Elantra XD (2001-06) :: Rough Idle Under 1000 RPM - Sputtering Backfire
Nov 13, 2008
2003 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.

Starts fine. Runs fine till warmed up. Then dies at idle and runs rough on gear till 1000 rpm. Has only coded iac when unplugged. But would idle with it unplugged. I replaced it. Also got crank can code once while checking it ...

Below is a link to a video showing what my 2003 Hyundai Elantra is doing. It is idling very rough (Jerks at idle) and can actually be heard in the exhaust. I think it may be miss firing?? Does not do it at speeds over 60. Under 60 it can be felt at times, but only at low RPMs. [URL] ....

I have an '04 Elantra GLS with 274k on it. I've been caring for it myself with basic maintenance; that said, I changed the oil in it about 100 miles ago. Halfway through my drive home it started to idle rough under 1k rpm.
I've noticed a lot of other Hyundai's have the same issue. What would be/is the most COMMON cause of this? Timing belt? Basic tune up? I moved a state away from my local shop and I refuse to go to a Midas/Jiffy/ect.

2002 elantra hesitates and sometimes stalls staring from rest. Worse when cold but still sluggish after warm up. Where do I start?

Audi A3 3.2 owner here from Fortitude and have rough / lumpy idle issues? While at a stop in neutral w/a cold or warm engine, it seems a little rougher than one would expect. If you rev it to 1000-1100 rpm the whole car shakes.
Engine Mounts worn?
APR Software causation?
Cam Followers or faulty coils?
Do I need a heavier duty front and top engine mount?
Wondering if CAI and Exhaust along w/ the APR ECU tune is causing it or if I'm just being paranoid.

I have a 2005 Mazda 6. When it is cold - I start the vehicle & begin to drive. When I slow down and the RPMS get around 1000 - the car begins to run really rough & try to stall. If I put my foot on the gas - I can usually prevent it from stalling. The problem disappears once the car gets warm. The dealership recalibrated the PCM based on a Mazda Alert. However, it has not corrected the issue. Looking for thoughts on what could be causing this?

I just picked up an 02 Hyundai elantra manual trans that needed a transmission. ran fine before I replaced transmission but after putting it all back together the car now how has an erratic idle. it will rev from 2-4000 rpms. I tried spraying for vacuum leaks idle didn't pick up any higher. replaced tps and iac and didn't make a difference. the only thing that did make any difference is unplugging map sensor. dropped idle to about 1200 rpm but ran rough. could this affect the idle.

I have a 2001 Elantra with 170K miles. well taken care of. I've been having a rough idle issue for some time now. The car idles very rough. I checked for codes and I got the cylinder 2 misfire code (P0302)...
I started out and replaced the plugs and wires, no solution...
I replaced the coil packs, no solution...
I replaced the MAP sensor, no solution...
I figured it may be no to low compression, so I did a compression test and all cylinders came back normal, still no solution...
I figured it might be a dirty injector, so I poured some seafoam in the gas tank, and no solution...
So my next step is to switch out the injector. Is there anything I am overlooking?
Here's the big thing that is happening too... Everytime I fill up the gas tank, I turn the car on and it idles even rougher. Like if you talk while sitting in the car, you sound like Chevy Chase when he is on the vibrating bed with Beverly D'Angelo in the movie vacation! LOL. It slowly goes away after 10-15 minutes of driving. All this rough running engine ONLY happens at idle, otherwise it runs very smoothly.

I have a 2008 Ford Focus - 4 Door Sedan SE 60300 miles.
I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.

I have a 2001 f150 5.4 liter 2 wheel drive super crew that idles rough with surges in the idle. Weird thing is it only does it when it's 55 degrees or below. So it's fine now in the heat but winter is coming and the colder it is the worse the idle. Replaced maf sensor.

09 tiguan that was bought in august of this year as a certified pre owned and has a warranty on it until 60k miles or 2014. Recently there has been some issues with the car stalling out and sometimes having a very low rough idle and then the idle will pick up and the car will surge slightly then it will be fine for a while. I have my suspicions that it is because this is my fiance's car and she has been putting mid grade gas in the car lately. Also we cannot get the fuel door to open now is there any tricks on getting it open?

2010 F150 ... So I have the tick noise at rpm's 800-1000 at drive through, stops, etc. So I did research on it a few months ago and saw that it might be VCT's but should be able to drive. so I drove it waiting to save money and have it go to a shop. well this past weekend while coming home from work my oil light came on the pressure dropped to zero, I was on the highway so I drove about another mile to get off highway and once I got off my truck died. I had it towed to my house and I thought I blew my motor. So I started doing research here and found that the VCT's AND cam Phaser could be bad. so I replaced my VCT on driver side put it all back together it started and loud knock was gone. then after 5 mins it was back very loud knock!
So I shut it down and took apart the passenger side once I got the valve cover off I found the problem.... The bolt that holds the cam phaser in place snapped off and was riding along the camshaft. So I took that out and extracted remaining part of bolt. inspected my camshaft and it was really messed up. so I bought new Phaser and Camshaft. the camshaft just came in today and I am trying to put it back in. but the hole for the pin in the phaser doesn't line up and I cant spin the shaft to make it line up. should I spin the cam phaser? I marked the chain and the phaser is where it should be on chain, but with that bolt snapping off could that have thrown the timing off so my mark is no good? when I lay the camshaft in place it sits perfect and if I just move the phase over 2-3 links it will all fit together. Should I do that?

2001 GL 1.5 Litre. Car occasionally hesitates a little with AC off, but runs pretty well. But with the air conditioner on?
Stalls about 50% of time when backing with A/C on. From stoplights, sputters all the way through intersections with A/C on, sometimes backfires. On a few occasions, the Check Engine light will blink on and off while it's doing this. After it gains a little speed/rpm, though, it's all good again, light goes back off.
Had full tune-up just before we bought it 4,000 miles ago. Air filter clean. Not sensors, because the CEL goes back off by itself. What the heck? How could the A/C cause a backfire?

Today I went and test drove a used 2006 Dodge Stratus SXT from a private party. Everything about the car was great except it had a bit of a rough idle; there was a slight sputtering noise when not in motion, and the car itself vibrated very slightly. It didn't bother me too much while I was driving because it accelerated and shifted fine and the engine sounded very strong, otherwise.
When the test drive was over I pointed out the noise to the owner, and he admitted that he had mis-timed the timing belt slightly which was causing the sputtering (he is a mechanic and replaced it himself). I was worried about this, but I did some research when I got home and learned that this model of Stratus has a non-interference engine.
My question is this: should that timing belt be a deal breaker for me? Will this cause major mechanical issues down the road? I know it will reduce power but I only really need the car to commute, so I don't mind if I'm not toe-to-toe with a Challenger. I'm just worried it will eventually cause a costly problem.

My new 2015 Sonata 2.0Twith 8000 miles started running oddly about 2 weeks ago. Rough idle with engine "sputtering". Erratic acceleration -- merging into traffic on highway and car not going over 40mph, even with gas pedal all the way to the floor. On deceleration, clunky down-shifting. Very hard to drive. Dealership first came back with diagnosis of "buildup on throttle plate" (Note - I use only high-quality gas AND only have 8000 miles on car, 3500 or that being one long highway road trip). Then, after 3 days of diagnosis, they say I need 2 new fuel injectors I am baffled how a new car can have either buildup or failed fuel injectors...
