Since having my engine replaced with a newer used engine block my idle speed when I first start it up or when it is cold is around 2000rpm which lasts for about 2-3 minutes until it begins to fall to the normal range of 1200-1400 and finally to 850 or 900rpm when warm. how can I fix this or is it okay to idle at 2000rpm for a couple of minutes? is it hurting anything?

View 4 RepliesPassat (B6) :: V6 Runs Rough For 1 - 2 Minutes At Startup When Cold
My V6 3.2l runs very rough for 1-2 minutes at startup when cold i.e. the first startup of the day, or after it has not been driven for several hours. Is this normal? I understand this might be something to do with the 'anti-knocking' feature. But I only use RON 98. Also I can here something like a tappet sticking when idle all the time. Is this normal, is it just a noisy engine design? The car has only done 1800kms.
View 2 RepliesChevrolet - Equinox :: 2005 - Runs Rough When Cold
I have a 2005 Chevy Equinox with 73K miles. When I first start it up morning the car runs rough for about a minute or two and then smooths out. I took it to a mechanic who said there was oil on one of the plugs and to get rid of the car. I tried another mechanic on Craigslist and he replaced the upper plenum gaskets. It ran better for about a day or two and now the problem has resurfaced.

I replaced my engine that had 155,000 miles with a newer used one with about 30,000 miles. since the swap my gas mileage is down by one third or more. Everything else seems fine except that my cold start idle is up to 2000rpm's until it drops to normal within 3 minutes.
View 2 RepliesToyota - Corolla :: At Idle Car Runs Very Rough But Can Accelerate Up To About 50 MPH
I have a 2000 Corolla with about 147,000 miles. At idle it runs very rough, but can accelerate up to about 50 mph. Then it starts to cough and wheeze and run roughly again and won't accelerate any further. It feels like the engine will shake itself off its mounts, so I slow down and stay under 50 mph. I replaced spark plugs and a repair place hooked it up to a computer. They then told me it needed about 1800 dollars worth of repairs to replace the valve cam I think they said. I'm skeptical and wonder if it just needs a tune up, . It has not had one since I bought it at 128,000 miles, and II don't know how long it had been prior to that.
View 5 RepliesPassat (B5) :: 2000 - Runs Rough With A/C On?
The car is a 2000 passat v6 with ~135k, auto trans. Well when the car is cranked it takes a bit to get running and once it does, black(wet) specs come out the exhaust and go all cover the surrounding area of the tailpipe. When the a/c is off it almost sounds like it is running normal but when the a/c is on(at idle) the engine runs very rough, it almost sounds like a misfire. It does have a check engine light, but i have no obd2 scanner, and from what i've been reading might not even do me any good because of vag com?
View 5 RepliesLS / MKZ :: 2002 Lincoln Idles Rough On Cold Mornings But Runs Fine
The car idles rough on cold mornings but runs fine. It will stall while idling but starts back easily. I am getting a 1131 and a 1151 code with my scanner along with 0300 and lean bank 1 codes. I started having these problems after I had to remove the upper intake to replace coil packs. I was getting egr code and had an egr port completely block off but cleaned that out and no longer get the egr codes. Spraying carb cleaner around the engine I get a very slight bump in rpm around a couple of the intake ports could that be my problem or should I look deeper?
View 5 RepliesFord F-150 (2004-2008) :: Runs Rough And Idles Poorly Only When Cold
I recently replaced the plugs cuz I had a rough idle all the time. During plug change when I discovered they had already been changed I found one that had a burned off electrode. Does this mean a lean condition exists?
After plug change it runs smoothly but only after 10 min warmup in our canadian winters. I can drive it when its not warm but seems to have less than full power and idles very badly after driving w/o proper warmup.
Next I changed fuel filter and checked fpdm, it was a little rusty but not bad so i just mounted it 1/4 off steel to prevent further rusting.
Since then I have installed a programmer [diablosport] but found no codes since i had battery disconnected for filter change. no new codes in last few weeks since.
So do I have a lean running cylinder causing this poor cold idle or a rich cylinder? It must be a clogged or dripping fuel injector right?
Toyota - Pickup :: 1981 - Refuse To Idle / Only Sputters And Runs Rough
I have a 1981 Toyota pickup. when i start her. she starts fine, but sometimes she will idle fine, and then suddenly refuse to. it seems to be random. i can keep her running if i keep my foot on the gas just a little, to keep her rpm's up. but have to put her into N and keep my right foot on the gas and my left on the brake to stop her when she refuses to idle. when she does this on the freeway, it just sputters and runs rough, but as long as i have the gas on, she keeps going.
I don't know what it is that regulates the idle to keep her going when my foot isn't on the gas. also her serpentine belt is slipping. the one attached to the alternator, i can see her charge voltage dropping when she squeals her belt. that i know how to fix, but i'm wondering if it's that, that is the issue? i was told that, but i don't think her serpentine belt has anything to do with her idling. i was told how to raise her idle on the throttle cable and the Idle screw, but is there something else that regulates her idling?

View 2 RepliesFord Ranger / B-Series :: Runs Rough For About A Minute After Engine Started When Cold
This has been an ongoing issue for about a month. When I start the engine after it has been sitting and is cold it runs ruff for about a minute then smooths out and runs fine. I pulled a P0304 code (cyl.4 missfire) but I do not get a CEL.
I checked the plugs and they were ok but I changed them and the wires anyway as it just turned 50k and the plugs were original. I could live with a little cold ruff idle but the code throwing bothers me. The truck is a 2000 xlt 4x with auto trans. and 4.0 engine. This is my second 4.0 ranger but I have only had it for about 6 months.

I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.
View 7 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 Runs Rough When Cold
I have my 2002 Ford F250 Powerstroke. 175,000 original miles by me and only me. SCT, MBRP, Howes or Stanandyne almost always. Runs like new. It starts rough if I don't plug it in. Even on 50 degree days. Then it levels off and runs perfectly. If I plug the truck in I can drive off immediately with perfect operation of motor. I just went 1500 miles. Pulling a car hauler with car. NP at all.
New Glow Plugs, GPR "Yes it works", IPR, New Harness, Buzz Test shows it's fine, New #8 injector last year, New O rings HPOP. My buddy who is a PStroke guy said this trucks runs too perfect for it to be injectors. He recommends seals for the injectors. What does this mean. Or what else can it be. Where should I start.
Ford 6.0L Power Stroke Diesel :: 2003 - Hard To Start And Runs Rough When Cold
My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Truck Runs Rough When Cold
I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?
