Focus :: Ford Idles Rough Once Engine Starts Coming Up To Temperature
Dec 7, 2014
We have a Ford Focus wagon that idles rough once the engine starts coming up to temperature. When you first start the car it's fine. For example, today I started the car, drove it up the road to the store and it was fine, but upon returning to my driveway just a few minutes later, as the engine temperature was just starting to come up, it started idling really rough. The idle is so rough it sounds like it's on the verge of stalling, but it never has actually stalled. An oxygen sensor has been replaced and it was good for a while, but now the problem is back. The check engine light is on as well.

The problem I have is when it is cold out under 40 degrees, my car starts rough and idles rough until it gets to temperature. My research has concluded it may be cold start. Does this sound right?

When I first start out driving the car, and come to a stop, in drive, the car begins to run rough. I can hear and feel the vibration, it's very noticeable. I put it in neutral and it stops. As I load the engine with AC or use the electric windows it seems to gets worse. Then after driving for about 5-7 miles, it quits. Primarily in cold weather, since it started 4 months ago. I do allow the car to warm up before driving.I'm still under warranty, and have been to the dealer 3 times. Of course, it doesn't happen when I go to see the dealer. But they did re-tighten the motor mounts. I don't think it worked.

02 Passat 4Motion with the 3.0L V6. I just had the car at the dealer 2 weeks ago for the 50K service and to have the temperature gauge fixed. Otherwise, the car was running just fine. At the service, they replaced the water temp sensor, performed a fuel injector service and radiator flush (both recommended).
Now two weeks later, her car rough idles, dies and has to be towed to the same dealership. They first diagnose fouled plugs which they replace gratis. They then tell me the plugs fouled because the ignition coil and wires have gone bad and need to be replaced. They want to do an additional injector/intake cleaning service. They are offering to discount the services slightly. I'm still going to be out another $850.
I called Volkswagen Customer Service and they confirmed that the ignition coils were not covered under the recall.
Something sounds "off" to me. The car was running fine before the initial service. Was the dealer just being "nice" in comparing the plug replacement or did he think that they initial fuel injector service may have fouled the plugs? I don't really want to pay 2x for the same service and now the coil/wire replacement.

I just got a 4.6 4WD Explorer in for rough running. It had timing chain noise and some odd codes for primary coil H codes along with cylinder 8 misfire.
I replaced the coil to get rid of the "H" code and it was fine. Still misfires on 8, and I really don't care because it's coincidence that the timing could be affecting it or perhaps.... bent valves!
The vehicle starts and idles a bit rough. Can't go very fast, and of course I know I should run it as little as possible!
Here is the deal, how should I present this to the customer? Should I let him know that some valves could be bent after replacing the chain (and all associated parts) and that it could still be effed? Or will I be fine after replacing? Pretty much, where they had a tensioner failure/guide breakage and valves bent too?

I just replaced the water pump and put it all back together, now it won't run well enough to drive. Checked vacuum system, all sensor connections, hoses, gas cap, changed fuel filter, I can hear the fuel pump kick in, reset system with battery disconnected and have looked at everything I can think of so far.
Now - starts fine, idles about 10 seconds and then begins to idle rough and dies. If I use the throttle I can often keep the idle up, but then backfires or acts like no fuel and again dies. Used fuel cleaner and made sure there was plenty fuel in tank.
I am looking at replacing sensors at this point but which one first?? They get a bit expensive real quick.

I have a 2003 2.0 gas Jetta (181k miles, automatic.) that won't rev over 3k, starts rough, idles rough and wont stop setting a P0341 cam position sensor code.
The car was not running when i got it, i replaced the coil pack and it ran but not over 3k. Cleared codes, it sets the P0341 immediately.
Had timing belt, water pump, tensioner and cam pos sensor replaced. Still, sets p0341 code, starts rough, idles rough and wont rev over 3k.
The throttle servo makes a little noise when actuated, shop thinks this is my demon - suggests replace throttle body.

Just recently my Prius Taxi with 340,000+Km has developed a little problem,it starts fine but after 20-30 seconds it begins to feel like it's not running properly on all four cylinders,if i go to the exhaust pipe it seems like it's spluttering slightly.
Yesterday I changed the plugs,checked air filter and all connections,everything fine, when I accelerate it feels hesitant but after the car gets up to temp it seems to go away,it only happens when i start it first thing or if it's been left for a few hours, it's never had the throttle body cleaned and I'm wondering if what I'm describing is a symptom of this?

1991 Regal, 3800 v6.
So here's an interesting observation. When i turn the ignition to ON, I hear no sound nor feel any vibration from the fuel pump. Is there any scenario where a fuel pump fails to prime yet kicks into gear after a start? So, I've got rough idles and misfires on cold starts. Before I start replacing parts my diagnostic plans is as follows:
Remove and inspect spark plugs.
Inspect and test starter coil/distributor (still have to research how to do this)
Test resistance on fuel injectors.
Test pressure drop on fuel rails.
Test compression for possible small head leak.
I'm wondering, if I do have a tiny head leak that is letting in a drip or two of coolant after hours of the engine sitting, will I be able to see this on the gauge doing a compression test? I've never done one before and still need to buy a gauge, but maybe I'm better off just doing the other tests and if they all check out I can be certain it is a minor head leak.
My assumption is that I have a leaking injector; just trying to do things the proper way.

My 94 850 turbo wagon starts rough and idles very high. the rpms dont come down. After turning car off, wont restart again unless I let in sit for a while.

Idles really high at startup until the engine gets to normal operating temperature and falls back to normal. Takes 10-15 minutes. I recently de-greased the engine and think I may have fouled a sensor...though the check engine light is NOT on. I'm afraid if I keep this the way it is it will cause damage to the engine.

I recently bought a 2001 Ford Focus (about 4 months ago) and it recently began having a rough idle, check engine light, and stalling. One night, I started and it immediately stalled. When I tried to drive it, it made a grinding noise. Eventually, I made it home and got it to a shop the next day. I was told that it was likely the pistons by a mechanic. He later confirmed it was the pistons, had them replaced, sent my engine off to a machine shop for "smoothing". 2 days later, I had it back and it seemed to be running great. Took it to work and went up a small grade hill (not even labeled) and it began chugging, making a grinding noise and the check engine light began flashing.
I took it back to the shop where the mechanic couldn't even keep it running and he determined that it was a broken hose. He replaced it, free of charge and the car ran great for a couple days. Next thing you know, it begins the rough idle and random stalling but no check engine light. I took it back in and he asked to keep it for a few days. He said that he determined the machine shop didn't do things correctly and sent it back in. I got it back this morning and it seemed to be running fine for my husband, but once I got in it, there was a loud rumble and a slightly rough idle. Then, there was the smell of burnt rubber. My mechanic wants it back, but isn't open again until Monday and I work the next two days. By the time I got it home from work, it had a very rough idle, issues accelerating and I'm still having issues going up hills.
Clearly, my mechanic is really focused on the issue being related solely to my pistons and is only focusing on that. I think something else is wrong and is being missed, but I have no clue what.

my 2000 focus se, 2.0L SPI, with 82k began to recently run rough at idle then progressed to stalling at longer lengths of idle. The condition starts once the engine warms after 2-5 minutes. I 1st tried gas treatment. I replaced the ignition coil as suggested in the other threads, but it has not improved the problem. I had the fuel pump recall-replaced 2 years ago. I would guess that a bad fuel pump would exhibit loss of power at all engine speeds? Before I proceed to replace plug wires and plugs.

So I have a 96 Dodge Dakota SLT 3.9 4WD. Anyway, it idles relatively smoothly at about 700 RPM in drive or neutral, but if I'm in a moving gear and need to stop, the idle is extremely rough. Usually, the RPM's will drop to near 0 within about 20 seconds of coming to a stop. It will typically recover and continue with rough idling and near stalling a few times, but within a minute or two it stalls. A few additional details: it starts right up again after falling, it doesn't make any difference if I start it cold and drive immediately or drive it for an hour before coming to a stop, the same thing happens. Anything that looked suspicious to me has been changed (drive belt, spark plugs & wires, distributor cap & rotor, pcv valve, idle air control valve, and, of course, the air freshener).

Like the title says I'm having an issue the past few days where I can't drive this truck more than a few miles before it starts acting up with rough idle at stoplights/sign and sluggish acceleration until it gets over 1200+rpm.
Cold starts fine, drives good till engine warms up to around 130+ECT then it starts acting up. Stumbles on acceleration for little bit and puts out a little black smoke until it gets moving. No check engine light or codes found.
However a month ago I had the check engine light come on with a P0404 & P0405 and it still started & ran/drove great even towing. If I reset the code it would stay off until I restarted the engine the next time. I replaced the Dorman EGR because it had a lifetime warranty and only had 5,000 miles on the first one. The code did not go away until about two weeks ago the light went off on the dash and has never come back but I had not erased the code? So I'm not sure if this is still lingering issue or what.
I was checking my ScangaugeII when I came back home today while the engine was still idling rough and this what I saw for Numbers:
Low idle in Park
ECT 193
EOT 191
FICM 49.0
IPR 21.4
ICP 582
ICV 0.81
V 13.8
TFC 1.91
VSS(fan speed) 0
(This one doesn't seem right in the past is 500 or more rpm from what I remember?) What am I missing to check over?

I just purchased a 2013 Ford Focus hatchback SE Monday night. Tuesday morning I came out of the house to get in my car, I unlocked the car, and opened the door. Before I even got into the car I heard a "scratch scratch scratch whirr whirr" coming from the engine. The dealer did not show me where the hood latch was so by the time I figured out how to open the hood the noise had stopped (within a minute of when it started.) Driving that day I did not notice any more noise, nor any issues with the engine.
Wednesday morning (today) I came out to get in my car, and when I opened the door I heard the same nose coming from under the hood. I got the hood open and looked in with a flashlight while the nose was still going. The noise was coming from the right hand side of the engine block, but I did not see anything actually moving to cause the scratching and whirring noise.

2010 Ford Focus. My fiancee noticed that when accelerating, the car has an electrical sounding whine coming from the engine. It only occurs when we're accelerating and pitches a bit higher when we're turning
We have until Thursday to return the return the car if their is an issue.
I've attached a video of her revving the engine.

I've switched the fuel pump on this car more than once and made sure the fuel line isn't crimped yet it still hesitates. Also, the temp. shoots up when idling and appears to need either a fan or temp. switch?

On a cold crank the engine idles rough until it warms or the accelerator is pressed down. Also runs rough going up hills or towing. Check engine light is on and is throwing the code for bank 1 to lean and cat performance below threshold. Cats have been tested, good. Fuel trim tested, good. One mechanic said noth8ng is wrong with it well, there is. 2011 f250 6.2 gas...

Well, a couple months ago my engine started making a noise. We located the issue to be a loose timing belt. We had it tightened, and the noise stopped, but since then it kind of acted like it was a little out of time with rough idles every now and then. This past week, I had driven my car out. I came to a 4-way stop and the car shut off on me. It would not immediately start back up so I pushed it to the side and waited a bit. It started up after sitting for a few minutes and cooling down. I got it back home and it stalled right as I was turning into my driveway (after the RPMs had lowered to idle).
A couple of days ago I set out to replace the timing belt as it seemed to me the timing was off ever since we tightened the belt and it eventually got worse, thus the stalling. I changed the timing belt, set the timing on the cams the way it shows to be set below:
I set the timing on the crankshaft pulley to the specifications found in this video:
Which is putting the crankshaft pulley on and turning it until it aligns with the '0' mark on the bottom timing cover. So I decide to start the car without anything else on to make sure its in time. It fires right up so I shut it off quickly and go about putting it all back together.
Once the car is completed, I attempt to start it again. It fires up, I back it up and it dies. It would not start back. I waited a few minutes and attempted to start it again, it started up so I pulled it back up to the same spot it was in and shut it off. Took the pieces off again, got it back to where I could line the timing up again. I again set the timing one more time to make sure. It was set correctly. I then tried starting the car again and this time it would not crank.
I gave up for now as its 30 degrees outside and I have been working on it non stop for 3 days to no avail.
