Subaru - B9-tribeca :: 2006 - Car Rough Idle / Engine Shaking For Few Seconds

I have Subaru B9 Tribeca 2006. Week ago started the following problems - after starting up, engine is shaking (rough idle) for a few (20-30) seconds and then it's OK. Then I got Check Engine, Cruise and ABS lights on. Diagnose shows mistake in 1st cylinder. changed spark plug, air filter, checked all connections, cleaned injector and throttle. Lights went out and engine was working as new. but the second day car had rough idle again....

Ford - Explorer :: 1999 - Misfiring / Shaking / Rough Idle - Engine Light Flashing

My 99 Explorer XLT V6 SOHC has been misfiring lately. In idle the RPM needle fluctuates a bit and the vehicle vibrates and shakes. At night when the lights are on I notice them dim a bit as the engine struggles in idle. It doesnt stall very often at all. Accelerating I notice way less power and the engine studders. Thats when the engine light comes on flashing. Then remains on solid afterwards.

I brought it to a mechanic friend who read the code and it was cylinder two misfire as well as O2 censor. I replaced the plugs and leads and censor. Noticed the plug in cylinder two had little to no gapping. Thought I had fixed the problem. Vehicle ran perfect. Three or four days later driving on the hwy same problem came back. Thinking it must be the coil pack I got one for a good price and replaced it.

Again, the truck ran great for four days and now the problem has returned. Same thing, shaking studdering and flashing engine light. I have verified the locations of the wires and plugs a few times so i believe they are all properly installed.

Accent MC (2006-11) :: Rough Idle At Stops

My 2011 Hyundai Accent 1.6 runs fantastic and has since I purchased it three year's ago until two weeks ago when my domestic partners friend changed the spark plugs, oil, air filter and stuff so I could go on a short trip and back. About 200 miles into it I pulled into a rest stop and noticed it was rough before I put it in park. As soon as I put it in reverse it was running rough and sounded like it was going to die. Forty miles later the check engine light was on and it was running terrible. A parts store recommended different spark plugs. A nice man who was there overheard the conversation and offered to put them in for me since I know nothing about doing. He said he gapped the spark plugs at 0.40? When I started it it ran like a dream until about 75 miles later and it began doing it again but the light never came on. It is doing the same thing which is a rough idle when stopped but it smooths out when I put it in park.

Windstar :: 2003 - Rough Idle When Sitting At Stops?

It is idling very rough at times, not all the time, when sitting at stop lights/signs. Sometimes it will stall out. 3 times it has stalled in the middle of an intersection while turning. Scary as hell! I Have to stop the van on the side of the road, put it in park, turn it off, then start it again before I can go. This process is getting Old!

While sitting at a stop sign/light, it's like the engine surges up and down. Some surges get low enough that the van will just die. If I step on the gas or put the van in neutral it will quit for a minute. All of the lights in, on, outside of the van go bright/dim with every surge. The battery light will occasionally flash on and off during the surges, but not every time.

Accent RB (2012+) :: Rough Idle / Stall At Stops And Tough Time Accelerating

Noticed this to be a problem with our older 2011 Accent, now with the 2012 Accent.

The car has a rough idle usually in mornings, it seems like it is going to stall at stops, it also has a tough time accelerating.

The computer scan does not show there is anything wrong until the problem becomes worse.

This is what I have discovered through the 2011 Accent. Car will stall at stops. Very inconvenient in rush hour traffic. Until they replace the Crankshaft Point Censor, the problem would not go away.

I would insist on looking at this rather than replacing sparkplugs or having any other service performed if one is experiencing these same symptoms. The good thing is it is under warranty.

Camry :: 2009 - Rough Idle / Dash Shaking

I have been searching and it seems I am not the only one who has a rough idle with the I4. It is very rough even without the A/C on. I can see the dash shaking, I can feel it in the steering wheel, brake pedal, seat, and arm rest.

The dealership cleaned my throttle body and MAP sensor (They forgot to put one of the screws back in the MAP). This is the third time they have cleaned them. When they returned it to me I told them to keep it until it is fixed. So they took it back in and decided that it might be the motor mounts so they went ahead and replaced them aside from the dogbone or whatever it's called.

When they returned the vehicle it was still having the same issue, they told me that its just the nature of the beast and to live with it. Well my neighbor has the exact same car, and yes it does have a SLIGHT vibration in gear but nothing like mine. I can't stand this car I really wish I would have bought something else.

I currently have 70,000 miles and for the last three oil changes I have been running Full Synthetic in hopes it would work but it has made no difference.

Just a note I have had multiple problems with this particular dealer lying to me. They even ripped up my passenger seat and would not fix it they said it was pre existing. I am over the seat I don't care anymore but I am tired of the rough idle. I plan on taking into another dealer but I am hesitant because they told me if there is no real problem I will have to pay in full for the diagnostic.

Yaris/Scion & Vitz :: 2001 Echo Cold Start / Car Seems To Idle Rough At Stops

I've been having trouble getting my 2001 toyotoa echo to start in the cold weather and STAY Idling. All I can do to keep the car going is hold my foot on the gas until it warms up, then it stays running, low idle, but running. It starts fine the rest of the day, but that first start in the morning doesn't take. The check engine light comes on and stays on, and the car seems to idle rough at stops.

At first the Mechanic I took it to (good guys) cleaned out my throttle body (physically and chemically) and this seemed to solve the problem for a couple weeks. I'm located in Toronto, Canada, and we're heading into cold weather and I just want a car that starts. It started up again recently and I'm now being told (on my second visit to the mechanic) that it's my throttle body/idle control and that this part needs to be replaced, to the tune of 627.00 + labour.

Accent RB (2012+) :: Rough Idle / Mild Shaking When Cold

I bought my 2012 Accent a few months ago. I have been noticing that when its cold it has a bit of a rough idle. Nothing bad, no reving, but just a general mild shaking. No check engine light either. It happens in park, reverse, neutral, and drive. It stops and runs smooth after a few mins of driving. Since I bought it I have been using Top Tier gas and a bottle of gumout at oil change. Could it be just the way the engine is, since it is a small 4cyl? Like I said its not bad or affecting the way it drives, just seems strange to me.

Toyota - Rough - Exhaustsystems - Corolla :: 2005 - Shaking When Idle?

My exhaust system was replaced on my 2005 Corolla in August. After driving it for just a few days, there was a shaking when the car idled. The mechanic replaced two engine mounts and the idle was much worse! He said it was ok to drive, so I started on my planned trip across the country. In Denver I took it to a mechanic at the Toyota dealer and they adjusted the throttle. It was better for a while, maybe a week and 1,000 miles. Now it is worse than ever! Having gotten two totally different causes from mechanics, I am not sure what to do next.

Also just before the exhaust sytem went, I had the 60,000 mile service done and had the car totally checked out by both Toyota, and an independent mechanic who specilizes in Japanese cars. After a car wash in California, the maintence required light came on.

What is going on?

Ford - Mountaineer :: 1998 V8 5.0 - Shaking At 40 MPH / Slightly Rough At Idle

A couple of days ago (Friday, Sept 14th), I noticed my 98 V8 5.0 liter Mountaineer was idling rough. I had the codes pulled and got P1401, P0455 and P0308. I did find a vacuum leak and fixed it (changed the air filter and cleaned the MAF while I was in there). I also replaced all the plugs (based on the P0308 misfire). I cleared the codes after that with a neg battery pull.

I'm still running slightly rough at idle, but not as bad. However, I have found that when I get up to about 45MPH (1500 RPMs) I started to get a worrisome shaking/ vibration. It's difficult to tell where it is coming from. If I let off the gas, or give it more and go up to about 50 mph, the shaking stops. It is only when I'm pressing the pedal in this range (like it is having trouble switching gears, perhaps?). Over the past two days of driving it and testing, I have been to autozone and had the codes checked. Nothing comes up, and no CEL.

I just had a new trans put on about 6 months ago. The only thing that preceded this issue was I got an oil change the day before this started at a place I don't normally go to (unlikely, but since they didn't write the type of oil they used on my window tag, I figured I'd mention it). I've read some suggest it to be a tire issue; but that strokes me as odd, since the shaking only happens when applying gas.

Volkswagen - Rabbit :: 2008 Car Started To Rev A Bit / Idle Has Been Rough With Some Light Shaking

I have a great vw 2008 rabbit with 115,00 miles on her. I just completed a round trip. On my way back during terrible stop and go Washington DC traffic..I noticed the car started to rev a bit. After that the idle has been rough with some light shaking. No engine light, but it does sound almost like it is choking a bit. Not extreme..but definitely not the smooth engine sound I had. I am guilty of NEVER HAVING MAINTENANCE on her..so I had new spark plugs put in and a new air filter. The problem is less..but the idle is still on the rough side.

Touareg :: 2004 Misfires - Rough Idle And Hesitating / Shaking Under Acceleration

It's a 2004 V8 Touareg with 100k miles.

Getting horrible misfires and they're jumping around to different cylinders + other intermittent codes. The symptoms are ROUGH idle, and hesitating/shaking under acceleration.

The MIL has never come on in this car. But, it illuminates when you turn the key forward. (Almost like previous owner coded the light out?)

Replaced all 8 spark plugs, just ordered 8 new ignition coils. Hoping the misfires are the coil packs but obviously theres some other stuff going on here.

Pulled codes 2 weeks ago:

1) random/multiple misfire (P0300)

2) misfire cylinder 4 (P0304)

3) misfire cylinder 8 (P0308 )

4) warm up catalyst efficiency below threshold bank 2 (P0431)

5) secondary air injection system insufficient flow bank 1 (P0491)

6) secondary air injection system insufficient flow bank 2 (P0492)

7) 02 Sensor Circuit Slow Response Bank 2 Sensor 1 (P0153)

Pulled codes 1 week ago:

1) random/multiple misfire (P0300)

2) misfire cylinder 2 (P0302)

3) misfire cylinder 3 (P0303)

4) 02 Sensor Circuit Slow Response Bank 2 Sensor 1 (P0153)

Pulled codes tonight:

1) random/multiple misfire (P0300)

2) misfire cylinder 2 (P0302)

3) misfire cylinder 3 (P0303)

4) misfire cylinder 4 (P0304)

Cleared codes. Swapped ignition coils from 2 & 3 with 7 & 8. Drove around the block, then re-ran them:

1) random/multiple misfire (P0300)

2) misfire cylinder 4 (P0304)

3) misfire cylinder 5 (P0305)

4) misfire cylinder 6 (P0206)

5) misfire cylinder 7 (P0307)

6) misfire cylinder 8 (P0308 )

Stalling - Ford - Focus :: Rough Idle / Shaking When Gets Under 1000 RPMs

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.

Ford 6.0L Power Stroke Diesel :: Rough Idle - Shaking At 1500 - 2000 Rpm?

I'm having a problem with my 6.0 back in September I started to notice a little miss with some black and white smock while accelerating so I took the truck to a power stroke specialist near my house to have it diagnosed they said my number 5 injector was starting to go bad so just this last week I finally got up enough money to get the injector changed I got the truck back yesterday from the mechanic. While driving I get a lot of shaking right around 1500 to 2000 rpms when I let off the accelerator it smooths out if I mash on it and keep the RPMs above 2000 it smooths out the truck still has a lot of power no check engine light has ever been on through this whole ordeal and there's a rough idle I guess the best way to describe the shacking would be if the truck was a standard shift and you were pulling a hill in to hi of a gear.

Prius (2004-09) :: 2007 - Rough Engine Idle?

My 2007 prius has been idling very roughly recently. It seems to be every time the petrol engine kicks in when the main battery is low and charging. A few weeks back, the malfunction indicator light came on and i took it to the dealer. They said my spark plugs had a lot of carbon build up on them so they cleaned them up and put them back in. Also it was missfiring from time to time. The light went away but it is still idling rough if not rougher then before they cleaned the spark plugs. Its not just like that in the morning. Even if my car has been sitting in 40 degree celsius heat all day it still idles like that. They recommended I use better quallity fuel. I used to use E10 but when I was doing long drives, i filled up with normal unleded. I havent used E10 since then. It never had the rough idle problem when I was using E10 so I am curious to think my car may not like normal unleded. The fuel quality here in Brisbane Australia isnt known for its poor quallity. I'm not sure what to do next. People have recommeded for me to use Wynns Spitfire fuel treatment to keep the spark plugs and injectors clean.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Rough Idle / Shaking When Press Accelerator And RPM Go Above 2K

2001 f250 7.3L, 289,000 miles, changed the IPR and ICP, noticed the EBP tube was in two pieces. Would this cause the rough idle and shaking? IT started running rough and would die after a mile or two. Would have to wait 30 minutes before it would start again. That is when a buddy told me to change the IPR and ICP the ICP plug was covered in oil as well as the top of the ICP. So I changed the wiring plug as well. I originally cleaned and changed O-rings on IPR but then it wouldn't start, bought a new IPR and started but runs rough. I just started it with EBP tube removed and sensor unplugged. Idling rough when I press accelerator and RPM go above 2K it levels off pouring black smoke everywhere.
