Toyota - Sienna :: 1999 - Started Idling Rough And Missing Intermittently?
Jan 31, 2012
My wife stopped for gas at a Circle K, about two days later this Sienna started idling rough and missing. I put some Seafoam in it and it cleared up. About one week later, she gets gas again, at another Circle k,about two blocks from the other one. Again, the next day she comes home from work complaining of the van running rough. I took it out and it drove fine. Whenever this happens the Check Engine light comes on, so I ran a code reader on it and it tells me, "Miss detected on cylinder 3".
So I checked all the plug wires, took out the plug (which I had just changed back in Oct.) and checked it, it looked fine. I thought maybe it could be the coil, so I switched the coil to see if I got the same code reading on a different cylinder. I unhooked the battery to clear the code after switching the coils, started it up and still got the rough idle and code. I turned it off (the van) and go in the house, I come back out and start it and it's running fine. I go to the store and all is well, go inside the store for maybe 45 minutes, come back out and start it up, I get the rough idle and missing.
I ran the code reader on it again and cleared the code, then restarted it and it was running fine again. Whatever it is, it has something to do with starting the engine (a 3.1L). One time it will start up and drive fine, the next time it starts the rough idling and missing. I figured if it was the coil and I switched them and got the same code on a different cylinder I'd narrow it down, but so far it has been running normally.

I have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.

I have a 99 f450 with a 7.3. Here lately it has been "missing" when driving or idling, but only every now and then. When driving down the road it will start bucking and boiling black smoke out then the ses light will come on and like turning a switch everything clears up and it acts and drives normal.

I have a 2006 Toyota Sienna Van that has 111,000 miles on it. I have a problem with both the heat and a/c. If you have the heat on but are just idling, it begins to blow cool air. Likewise, if you run the a/c but are just idling the air begins to blow warm. In either case, if you rev the engine (either in park or nuetral say at a red light), the air gets warmer if the heat is on, or colder if the a/c is on. In other words, the temperature only works correctly if the rpm's are up. Could this be a stopped up heater core.

Coming home from a road trip we stopped for gas not 5 minutes later the check engine light started flashing. The car was fine as long as you were puching on the gas but as soon as you slowed to a stop it would either die or shudder until I gave it some more gas. Being stupid I figured that I could probably get it home since It was only 25 miles of freeway driving and I wouldn't have to stop until I got near my home. I took it to a mechanic the next day and they said that it was my timing belt.
The next day I get a call from them telling me my timing belt is fine but they discovered that a valve adjuster shim is missing on cylinder 6 and the adjuster cup is jammed down as well as a crack in the locating pin hole so that the pin is moving causing the cam to shift in relation to the cam gear. They suggested I rebuild or replace the cylinder heads and may need to replace the engine. What this could be?

I have a 2007 F250 4X4 6.0 diesel. When first started it idles extremely rough to a point it sounds like a old gas engine missing. But after it warms up for about 15 minutes it runs and idles like a new truck. I'm thinking it's the injectors if so is this something I can change/clean ....

1999 Ford F-150 V8 5.4L... The other day I was attempting to fix my 4wd. I discovered that the vacuum tube by the 4wd solenoid had become disconnected. I reconnected it and in an effort to see if my fix was successful, I drove my truck up one of the canyons nearby. I got to an area full of loose rock and popped my truck into 4wd. As soon as I began to drive, the truck started idling very rough and died. I attempted to restart it for the next few minutes unsuccessfully. I got it started once and it continued to idle rough for a few seconds and died. I have not been able to start it since. It turns over but will not crank. It is not throwing any error codes. What I have checked so far:
Spark plugs are working.
When turning the ignition into the ON position, I am able to hear the fuel pump working.
I have not seen any cracks in the vacuum hose.
All the fuses are still okay.
What the culprit may be?

My headlights and dash illumination lights will intermittently flicker when I use the turn indicator to signal a right hand turn. Is it possible that there is a short in the turn indicator/high-low beam headlight control switch that is causing this?

I have a 2014 Toyota Sienna that I bought new last year that currently has 10,000 miles on it. I was driving home today when the car stalled, and smoke started coming out of the front. Firefighters came and took out the air filter, which burst into flames. They said they had never seen anything like it before. They looked over the air filter box thoroughly, said there was no more threat of fire damage but that it smelled like an electrical issue, and I had the car towed to the dealership. The dealer called me and said they "found" a cigarette butt and theorized that a lit cigarette was sucked into the air intake, which caused the fire, and furthermore, I would be responsible for paying for the damages, because it was an "outside event" that wasn't covered under warranty. I do not believe it was a cigarette, because the firemen found no evidence of one, and neither did I when I took pictures of the air filter box. So my question is, is this possible? If so, doesn't this seem like a pretty big design flaw? I'm concerned that the dealer is just making this up, so they don't have to pay for anything. If that's the case, how can I ever feel safe driving this car again?

I have a 1997 volvo 850 that has started intermittently stalling. It usually happens when i'm idling, like at a stop sign or traffic light, but recently it did it on the freeway. I have taken it 6 times to the mechanic (5 times to one and finally having learned my lesson the last time to a new one) and they say it is one of 4 things, but can't figure out which of those 4 things it is until it stalls on them. which it hasn't done. it acts perfectly when at the mechanic's and then they always give it back to me, only for it to happen again. the last time the car ran beautifully for 6 weeks before stalling out on me again....... oh, and once they replaced my fuel pump which seemed to work for a while.

I have a weird intermittent problem. Sometimes when I start my explorer it will idle down and die immediately, I restart and it will idle about 400-600 really rough, sounds like it is missing. When I drive it it is jerky and the acceleration is sluggish but after I get it up to about 20 mph it clears out and then drives and idles fine until I shut it down. Plus these things only happen about every third time (on average) that I drive it. Lastly it's not giving me any codes. What this could be?

My 1995 Toyota Corolla DX with 180,000 miles is missing. It was missing intermittently, especially when idling and cold, and especially when I drove short distances to run errands and then restarted it. It got to the point where it was missing even when warm, and would stall out when idling (always restarted eventually). I took it in to a shop, and they replaced the spark plugs, spark plug wires, ignition coil (which was fried) and the distributor cap and rotor.
All of the low speed and idling problems are solved. However, it now misses intermittently when I drive on the highway, only when giving the car gas at speeds of 45 mph or higher. It doesn't miss when I am coasting, regardless of speed, and doesn't miss at all under 45 mph. This car drives too well under 45 to be headed to the scrap yard yet.

My 03 with a 5.4 has been hesitating a when you accelerate and cutting out as well as idling rough and die when you slow down. It does all this intermittently. Not every stop or every time you accelerate. I first got a code for the MAF and both banks running rich (PO102, PO172, PO175) so I cleaned the throttle body and MAF. The running rich code came back (PO172, PO175) so I then changed the MAF and air filter . It seemed to work for a day or so then my light came on and I figured the same code was back but to my surprise it was now both banks running lean(PO171, PO174) so I took my MAF back and got another one. It hasn't set a code yet but it is still running poorly. I have changed all the COP's and plugs as well ....

I have a 2000 Ls 3.9 V8 125,000 miles that started idling rough.I checked for codes and got p0171 (bank 1 lean), p0175 (bank 2 rich) and p0307(cylinder 7 misfire). I swapped cop and sparkplug from cylinder 7 to cylinder 5 and erased the codes.I ran the engine for a while and rechecked the codes to see if the misfire followed the cop and plug. They did not. I still get p0171,p0175 and p0307 (cylinder 7 misfire).

So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.

Owning a Hyundai. I have a problem and it seems to be pretty common but haven't gotten anywhere with it yet. Last week my 2004 accent 1.6 manual transmission started running rough. It was idling higher than normal and while driving would not go past a certain rpm (about 2500 if I had to guess,no tach). On the way home from work it was running this way and then started badly misfiring and shut off, when attempted to restart it would not. I pulled the codes with a scanner and got p2400, p0562, and p0121. I charged the battery and replaced the throttle position sensor, still won't start. I can hear the fuel pump kicking on when I turn on the ignition. Also found the ecu 1 fuse blown, replaced it and continued to attempt to start with no luck, fuse was blown again. Like I said I haven't owned the car long and I don't know much about it. I am not sure where to go from here and I don't know how all these symptoms are tied together.

I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.

Car is idling rough. Mechanic said it might be an oil restriction not getting to a sensor and advancing the timing.
