Explorer :: 1997 Rough Idle When Started After Sitting For Few Hours
Jan 27, 2005
I have a 1997 Explorer Sport 4.0 SOHC, 110,000 miles. When I start it in the morning or after sitting for a few hours, the idle is very rough. Most of the time it wont even stay running. My first thought was a vacuum leak. I found four leaks and repaired them, including the EGR valve control and the EGR solenoid. One stem on each was broken off. I bought these parts from the dealer and then tested the vacuum, which I now have vacuum pressure. The check engine light is on and doesnt read the "system evap emission control pressure sensor low" (vacuum leak) anymore, but it now reads "system too lean (bank 1) and system too lean (bank 2). I cleaned the IAC valve and have ran several bottles of injector cleaner through. My mechanic thinks it is the IAC, but when you disconnect the plug on it, the car will barely idle, so it must be working at least a little. I have seen suggestions for a fuel filter, which I am going to replace, but I am really lost here.

About 7 months ago my truck started cranking longer than normal to start after sitting for more than 2 hours. This went on for about 3 weeks, then it started normally again. (By longer crank time, i timed it between 5-7 seconds on average. Normal is about 2 seconds). Now it has started doing this again about 4 weeks ago. Now I'm thinking HPO slow leak. Yesterday all is good again. What should I be looking for as a starting point to fix this permanently? When it cranks longer, the icp stays at 0, the ipr goes to 77%. Then it just fires off. No slow build of pressure. You can see all my mods and updated parts in my sig. I wonder if one of the new dummy plug o-rings is starting to give up already after only 15k miles. (Batt voltage is at 13.9-14.2, ficm is at 49.5 steady).

I have a 2007 3.3L Sonata.
The car has been sitting for around 8 hours. Wh en I start it, the idle moves up and down about 100rmps. When I drive off there is a slight hesitation until I have driven for about 10-15 minutes. The idle is nice and steady after the too.
If I use a fuel system cleaner, it appears the car is fine for awhile and then the issue comes back.

I have 2007 explorer with the 4.6 V8....
Recently it started running horrible. Rough idle, drives badly, hesitation, etc. Check engine light is on, code P0171. I cannot find a vacuum leak, and i am pretty much at a loss. Before it started running poorly i replaced the thermostat, and flushed the coolant. I am assuming this is a coincidence.

My truck started to idle very rough. I pulled the codes and I got po308 and po316. First I changed plug #8, the electrode was nearly gone. I have never seen a plug in worse shape. Replaced that plug and fired it up, it still idled rough and threw the same codes. Next I moved the #8 coil pack to the #1 location and vice-versa, still the rough idle and same codes. Then I moved the #8 injector to the #1 location same results. Finally I tested compression in the #8 cylinder and it read 32psi ( not good) everything else read 150 to 160 psi. Squirted some oil into #8 and no difference in compression.The truck is a 2002 with 184,000 miles, it burns a quart of oil every couple weeks but still is in perfect shape. Should I bite the bullet and invest in a remanufactured engine for 2500.00? I put one in my 97 f 150 a few years ago with no problems.

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.

I am having problems with my 97 F150 6cyl. A couple of months ago, I noticed the truck after sitting for a few days without being started would not crank. After some trial and error, I found that turning the ignition switch on and off several times did the trick and the truck would crank right up. I was thinking this might be a fuel pump or fuel filter issue but, I'm not sure.
A couple of days ago I was going to drive the truck and did the ignition switch deal as usual and the truck cranked up but, there shortly after while just idling the motor died. I have tried and tried to crank it and it want start back. After thinking on it, I don't know if this is a fuel problem or not, or maybe even the ignition box.

When my Camry is in DRIVE and sitting at a red light for example, my car will shake. It feels like it idles rough. If I put it in neutral the shaking goes away... only when in drive.
I took it to Firestone who mentioned I had a dirty throttle body. So I get this cleaned and the shaking has significantly reduced. However after a few months I'm back at square one. Dirty throttle body and care is shaking again. (Yes air filter is clean)
I noticed two things that I think might be contributing... After 5,000 miles my oil is pretty black and very low. (Time for an oil change) When I swipe my finger on the exhaust pipe, its really black but no black smoke comes out. I don't see any oil leaks outside of the engine, its actually pretty clean.
So two questions, is the low oil and black exhaust pipe normal? Why would my throttle body keep getting dirty?

I have a 95 honda accord 2.2L, 135,000 miles. One day while sitting at a light the car started vibrating due to a rough idle problem. The idle speed is ok at about 750 rpm.

To start off I have replaced the MAF sensor in this car 3 times now, and have all new oxygen sensors and a new fuel pump. The most recent MAF sensor I have put in the vehichle was 2 months ago and I did it because The car would die while idling, however the mass air flow code did not show up on the cars diagnostic trouble codes. Yet this did solve the problem. The previous MAF sensor had been installed a year ago and failed on me, it was under warrantee. Now that I have installed this newest MAF sensor the car has been running fine until last month.
Since then It runs especially rough at idle and has a tendency to die when sitting for more than a minute in idle. This problem is on and off however, it can run fine one day and as soon as i start it up the next day the problem will reoccur. Now I am getting the DTC for the throttle position sensor, evaporative emission control valve, and throttle position sensor. And more recently, today the problem occurred again, the first time in a week, and now I am getting gray smoke out of the tailpipe. I would like to know if I should again, try to replace the MAF sensor, or if there is some other problem that the Sentra is prone to that I am unaware of.

I hear a squeaking noise when I start my car. It is mostly in the mornings. Sometimes other parts of the day also. I believe it is on cold start because I usually hear it when the car has been sitting for a few hours.
My first thought was that it may be the belt so I popped the hood and looked at it. The belt seemed nice and tight and there were no cracks or extensive wear on it.
Second thought was brakes. My front brake pads are good but rear brake pads are close to needing replacement. Sometimes when I brake I hear the squeaking noise but it is hard to tell because at time it feels like it is coming from other cars.
Could the brakes be the cause of this sound? Even though it is at start up and not constant.
Car is 2007 Sonata with 100k+ miles on it.

Car is hard to start when sitting about 9 hours or longer to a day without being started up it is hard to crank over, I am at a loss to what is causing it, the car has a new battery, new distributor rotor w/wires and cap, my car is an 1993 Nissan stanza ALTIMA GXE w/automatic seat-belts, the car is fully loaded Except for sun roof or heated seats, I do have 242360+ miles on the car. I kept the car well maintained from Nissan, and they can't find anything wrong with it. is this the case of just old age on the cars behalf? what I do notice is there's a slight drop in voltage reading on battery the night before to the next day, can a starter be my problem??

I have an 01 SuperCrew with the 4.6L and it's idling really rough. Last summer, the idle started to flux pretty bad with the a/c on and eventually, it started to spray coolant mix through the vents and I lost heating about the same time. So, local dealership changed out the heater core and that is working again.
Well...I still have the idle flux, it fluxes from between 400-1000rpm at idle with the a/c on, it's a constant flux....up/down/up/down/up/down. A/C off and the idle is rock-solid steady. Dealership has changed 4 ignition coils over the last couple of years along with an EGR or PCV (whatever it's called) valve as well, none of which was for the idle problem, but somewhat associated. Where I should be looking?

Truck (04 excursion, 2WD, early build 6.0, 160k) started missing and rough idle on way home from work after sitting all day in rain - parked. started fine in morning and drove to work with no trouble - it was raining over night too.
To get you up to speed. for a few weeks before had intermittent trouble starting. would fire up as normal, fast and loud, but then stall immediately (usually after sitting overnight). would start back up but with a little long on the key and some gas pedal action. only happen one out of ten or twenty starts and seemed to follow getting fuel in unknown locations while on a trip out of town. decided to change out fuel filters and drain separator. seemed to fix it for a week or so then it happened again two days before above event, while weather was dry. Not sure if related but only recent problem to speak of.
Back to current:
- no check engine light or codes (I have a scanner)
- stalled out close enough to home the night in question I rolled it into driveway and tried to start it while rolling in neutral - no start
- once parked in driveway also no start
- next evening wanted to get it into garage (to dry off) and it started but rough idle and missing. this was after 24 more hours sitting in rain.
- been in garage 24 more hours and this evening got it to run but same result (rough idle and hard start). tried to check connections (mainly FICM) and move wire loom around - still same.......
Where to check next, need some diagnostic...

My 1995 Buick Lesabre will intermittently drain the battery after sitting for about 12 hours. It is unpredictable. The battery was newly installed in December, 2010 and the alternator was tested at that time and about three weeks ago and proved to be recharging properly. This battery kill happens even when there is no visible sign of current usage, such as a dome light being left on. What I should look for in order to to find the source of the current drain?

I had left my car for about 30 hours without driving, which I've done before all winter with no issues. Went to start it up yesterday morning to head out and when the key FOB failed to open the door, I knew I was in trouble.
I unlocked the door manually, and put the key in to start it up and the Treg was completely dead and the key wouldn't release from the ignition. After a call to VW roadside assistance, and a jump start, it started right up and I dropped it off at the dealer for them to look at.
The service report says "diag and found low state of charge. charged battery and found passes tests. performed TSB 27-05-01 and cleaned ground point for battery. rechecked OK"
This is a V6 Touareg (there is a similar TSB I understand for V8s).

I have a 2005 Passat Wagon, V6, 2.8L. I purchased this car used about a year and a half ago with 10,000 mi. It now has 32,000. I have done all scheduled maintenance. About 8 mo ago I started noticing a problem when starting the car. It seems to take a while for it to "turn-over" while starting it up. We've taken it to two different VW dealerships to try and solve the problem. About 4 mo ago, one of the dealerships replaced the ignition coil. They were able to read a memory chip of some sort to identify the problem I was having. Since this repair however, the problem has begun again. There is no consistency. Hot or cold temp. After sitting several hours or only a few minutes. The problem happens about one out of every five starts.

My Corolla sometimes cranks longer than it should when starting. This happens if the car has been sitting for a few hours. Although it doesn't always happen.
It happens when the tank is full and empty. The weather has ranged from 100 down to 60 degrees. The car has 20k miles on it and has had regular dealer servicing. What's going on with it? Otherwise it runs fine

From the first day i bought this car i had a strange noise coming under the hood. Every time i leave my car for at least 2 hours parked and then started, when i do a few meters i hear a noise like a hydraulic valve comes in place and my brake pedal does a small movement. After that everything is normal.
