Elantra MD (2010-15) :: Slightly Rough Idle At Stop Lights
My 2011 Elantra has a slightly rough idle at stop lights. It doesn't happen ever time, and some people probably wouldn't even notice it, but at every few/several stops it idles a bit rough. When I recently had it in to Hyundai service for the ECM update, I asked them to take a look at it. Of course, they couldn't replicate it at the time, so they couldn't do anything to address it directly. The service manager asked if it happens when the A/C is on or off. While I didn't know the answer at the time, it seems to happen with it both on or off. He did say that the ECM update may address/fix the issue, but unfortunately it didn't. While it's not a big problem, it's a minor annoyance I'd like to get fixed (as I need to enjoy my ride at all times.

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.

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.

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.

View 2 RepliesElantra HD (2006-10) :: Rough Idle When AC Is On
I own a 2010 elantra. I'm going through plugs like crazy. I've changed it twice and the dealer has changed them twice for a total of 4 sets. I have 64000 Kms on my car. The problem is rough idle when ac is on. I'm assuming drag or load on the engine makes plugs work harder.. So the last two sets of plugs the dealer showed me the plug and the white spark plug casing was burned through? Kinda getting sick of the bandage approach the dealer is throwing at me. He said if it happens again which I'm sure it will they will sort it out in more detail to find the cause.

My 2006 Avalon Limited idles rough at times (at stop lights). Should I get a fuel system cleaning done? It has 52k miles and has probably not been done in the past. Would a fuel system cleaning work with rough idle? Can I do this myself or do I need to take it to the dealer?

Within the past few days my towncar has developed a rough idle. When I'm stopped at a light or stop sign it jumps and just plain idles rough. This also happens when I change speeds after either accelerate or decelerate. I travel an average of 80 miles a day total to and from work and my car has about 140,000 miles on it.

Car is an automatic 1.8T and has a rough idle when the car is in DRIVE and I am in a full stop. Car also idles rough when in park. Not sure if it is an idle valve stabilizer, or a coilpack? Car does drive well once in motion and does not feel like it lacks power.

This is my brother's 02 SE. 140k miles. 4cyl. He claims that the car is beginning to idle rough when he is stopped at a stop light and the AC is on. If i replace the spark plugs should that do it? I'm pretty sure it doesn't have spark plug wires cus that's what my dealer parts dept said. Motor mounts were replaced around 70k if that matters. The vibration is directly related to the AC being on.
I am also going to replace the serp. belt because there's a belt squeak when the motor is cold.

View 10 RepliesChevrolet - Cobalt :: 2006 - Rough Idle At Red Stop And When Using A/C Or Heater
I have a 2006 Chevy Cobalt 5 speed manual with 49k miles. For the last year the car idles rough at stop lights when the A/C or heater is turned on. The rough idling is not continuous but intermittent with the rpm falling just below 500 and returning to just under 1000. This is accompanied by a shuddering, as if the car is about to stall out. I should also mention that the car has a tendency to stall when rolling to a stop in 1st or 2nd gear. The check engine light comes on sporadically during fast acceleration, usually on a steep incline, when driving on the highway on ramp. A recent diagnostic indicated the need to replace the fuel filter and clean the fuel system, including the throttle body. Had these things done, but I'm still having the same issues with the car. I mentioned this to my mechanic and he said it may be a loose hose.
View 3 RepliesPassat (B6) :: Rough Idle / Stuttering And Stalling At Stop Lights
My vehicle has started to idle very rough, stuttering and almost dies at stop lights. It hesitates when accelerating, and really shakes and rattles if the AC is turned on. The check engine light and EPC lights are on. And even letting the foot off the brake in drive causes it to jerk along. I am up around 65k miles and have not had too many issues other than a fuel pump getting replaced last year. (the dealer first started replacing and charging me for many other items) I am scared to go back without trying to trouble shoot it myself.
What it could be and if there is anything I can try to correct it myself?
