Sierra :: 4.3L Running Rough When Cold - Engine Is Missing
We have been having issues with my son's 97 Sierra running rough when it is cold/damp. It feels like the engine is missing.
Today, which is warm and dry, it started running really bad and it was all he could do to limp it home. It seemed like it wanted to idle fine but when he tried to rev it up the tach would start jumping and it seemed like it was missing.
Could this be a bad cap/rotor? The engine has 200,000 miles and we've never changed the cap/rotor. I changed the plugs/wires probably 100,000 miles ago.
Ford - Explorer :: 2002 V8 - Engine Running Rough - Seems Missing?
On my V8 02 XLT Explorer the engine is running rough like it's missing.
I think a coil may have gone bad,,found a LOT of anti-freeze down in the spark plug hole.
Have replaced the intake but now need to fix the roughness.
Is there any easy way to check each coil? Or should I be checing something else?
Ford Ranger / B-Series :: 1999 - Running Rough / Missing And Surging At 50 To 70?
I live in Kansas and was home in Georgia for the last 2 weeks. The truck drove great there after a fuel up started missing and surging at 50 to 70 thought it might have been bad fuel. waited till it was low added Lucas fuel treatment and premium gas still was doing it. no check engine light. went to Advance and fuse for light was blown they checked and was getting mass air flow code. unplugged it and seemed to be better, not perfect but better. plugged it back in and went to do it again. Changed mass air flow night before the drive back to Kansas. Ran well from Savannah to north Georgia then started doing it again the rest of the way home. Going to have advance check code again.

The truck always ran perfect till two days ago. went to start it in the middle of the day , it would barely start, when it did it was missing bad. then seemed to clear up a little after about 30 seconds but still missing. they thought they got some bad fuel. so they dropped the tank cleaned it all out and got new fuel, no change.
Him and a so called mechanic "kid from fire stone" played around switching coil packs around from the injectors with no change. He tells me that the two front cylinders , one on each side are not firing. that those two spark plugs are coming out fuel soaked after running the truck. He thinks it dropped a lifter or push rod popped out of place.
I took my A/E over and came up with codes p0106 - map sensor, and p0135 - 02 sensor. i cleared them and started the truck, shut it back off ran codes again. He also said they pulled the 02 sensor and it still ran the same.
Ford 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough
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.
Ford Super Duty (1999-2016) :: 2007 F250 Running Rough / Missing On Cold Start
So, I have a 2007 f250 with the 6.0. When she's cold she starts fine but runs rough like she has a miss. When she warms up the miss goes away and it runs pretty good. But if I shut it off it won't start for about an hour or so.
ICP sensor has been replaced.
FICM is putting out 50v
Ford 6.0L Power Stroke Diesel :: Rough Running Like Missing When Cold / Puffs Of Blue Smoke From Tail Pipe
My truck has been having this issue pretty much since I have had it, but it seems to be getting worse, or so I think.
When the truck is cold, it does not want to move very well. Like it's missing, and it does this until it gets warmer. Also, I have puffs of blue smoke come out the tailpipe when this occurs with it cold.
Injectors? Injector o-rings? Stiction?
FICM volts are good at 46.5v-48v when cranking.

View 16 RepliesDodge - Stratus :: 1999 - Rough Idle At First And Now Always Running Rough
I have a 99 Dodge Stratus 4 cyl 2.4L, automatic.
It has been idling rough for a few months now. It feels just like it is misfiring. Tach confirms quick dip in rpm then return to normal idle. It has never actually stalled, just a quick rpm dip and subsequent shuddering, then recovers for a few seconds.
Also runs very rough, at 47-48 mph under light "cruising" load. Sounds crazy, but it does (did, see below) not happen at 45 or 50, just in the 47-48 mph range. Again, it feels like bad misfiring, with the car losing a lot of power and shuddering until I accelerate/decelerate away from this speed range.
NOW, over the last few days, the rough riding has gotten a lot worse, and occurs at all speeds. It is worse under load (mild acceleration, hills). Still feels like misfiring. Loss of power makes it hard to maintain speed up hills, at any speed. Also, today for the first time in its life the car backfired while trying to accelerate up a hill from a stop, at a speed of about 15 mph.
When idling, I can occasionally smell gas.
So, the coils are 2 years old, spark plug wires are 2 years old, spark plugs are 2 weeks old and air filter is 4 days old. Check engine light is NOT on and there are no error codes as of yesterday. Fluids are all good, except I am about the kick the stupid thing until it bleeds. Parts store suggested Idle Air Control Valve, but I am dubious, as this now happens at all speed.
Saturn - Aura :: Engine Missing And Rough Idle
I have a 2009 Saturn Aura, 4 cylinder, automatic transmission with 50,000 highway miles. Sometimes intermittently and sometimes all day long the engine will miss and has a rough idle. This can happen while waiting for a light, accelerating from a stop or while driving at speed on the highway. Weather does not seem to be a factor. Only once the engine was hard to start and ran very rough.
That is the only time over the past several months while experiencing this issue that a code was recorded in the computer. "misfire cylinder # 1" . The spark plugs were replaced and the #1 fuel injector was replaced. The misfire went away and returned. The number 1 and 4 coils were swapped and the misfire continues but no code appears in the computer to indicate which cylinder has the problem. I'd like to clear up the misfire, but also wonder why when the engine runs as rough as it does at times a code doesn't occur?
Impala - Chevrolet :: 1972 - Stalls When Idle?
I've been trying to get her up and running for awhile now in order to sell her. I bought the car from a neighbor who never drove it (only 50k miles on it) and my dad had a great idea to get some new parts for it...I just wanted the car as it was... So we replaced the original carb for a newer carb and my father did all he wanted to do to it (I do know he took off the distributor, did some thing with the clutch, and replaced the fuel line to the distributor).
Well, when all was said and done (after a year and a half), the car is back up and running BUT when it sits idle it stalls. It will only stay running when you keep on the accelerator to rev the engine. As soon as you let up, the RPMs drop and she stalls. He's not sure why it's doing it, and I'm even less sure.
What are some reasons/causes/possible fixes for this?
Passat (B6) :: Rough Start - Cylinders Missing For Like 5 Seconds Then Fine
When I start my car it seems like some of the cylinders are missing for like 5 seconds then runs fine. Sometimes its quite violent and this morning it stalled the first time I tried. The colder it is outside the worse this becomes.
The car is still under warranty, but you have to wait a week to get the car into the dealer here and a battery wouldn't be covered anyway. Here is what I have so far.
Bad battery : The car has 45k miles on it and as far as I know the battery is stock. Also, when I did the 40k service I seem to remember something about the battery on the invoice (I will look), but I was too busy worrying about the bald tires. I do generally leave my ipod plugged into my car stereo (which charges it) over night, so that is putting a drain on it. I am going to take it out of the car tonight and see if that makes a difference. I suppose I could take the battery to O'Reilly's and have them test it, but it seems like it would be in their best interest to lie.
Coolant temperature sensor : The car was recently in the shop and they said they found a small coolant leak and fixed it, maybe the sensor became damaged? Most reports I see about this suggest the car runs rough for much longer than mine and must be fed gas.
Ford - Explorer :: 2004 - Rough Idle Like Missing And Die Intermittently
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?

View 10 RepliesToyota - Sienna :: 1999 - Started Idling Rough And Missing Intermittently?
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.
