I recently got my Mk7 1.8T manual brand new and have been wondering about the long cold start idle. It usually takes around a minute or two before the revs drop below 1000. Coming from a '04 Mercedes and '11 TDI Jetta, I can say those cars the idles dropped much faster. Is this normal with the golf?
View 11 RepliesHow to go about fixing my 1987 AMC eagle. I recently just purchased the service manual and am trying to figure out what I should repair first. I noticed a few weeks ago my car wouldn't idle in the cold.After bringing it to the shop multiple times it still does not run right. In fact, it seems to have gotten worse and has even died while going around 45 mph. Once it does die I find it very difficult to start. I have noticed some bad smells while trying to start it again sometimes gas..sometimes almost a burning rubber smell. (The belts are still in tact) Once it starts again it acts much like it had gotten flooded.
The motor seems to be fine and sounds good when running at proper temp. Recently, it will even die when the engine is all warmed up.Often when I get back in the car after driving it (while engine is still warm) I can turn it over almost instantaneously it doesn't necessarily sound good though. I noticed before all of this began that it would putter when going down a steep hill (or letting off of gas). Do I need to rebuild the carburetor ? Could it be as simple as a bad pcv valve? I have already put in 600+ into fixing this and no results. I am pretty convinced it some sort of fuel issue. I am also concerned the choke might be sticking and needs adjusting.
I brought it into the shop and they tightened the timing belt and secured some loose battery cables. They also said I needed to replace the battery which I then did. This did nothing to improve the how well my car ran. I brought it back and they replaced the distributor cap and adjusted the timing which apparently was way off. This did improve the performance of the vehicle but did not stop it from dying.
just got my R32 a year and 3 months ago and love it. I came across my first issue though a couple months ago, when i start my car on cold starts before it would of course go to the cold start mode at over 1,000 rpm's before going back down after 30 seconds and depending on the weather i'd let it warm up anywhere from 5-15 minutes.
Well a couple months ago my car wouldn't do its normal cold start routine, i'd turn it and it made its loud pitch as if it was going to do the cold start and it just immediately went down to regular idle skipping the warm up, it did this for a week before i got it checked out. I went to a shop by me and he said that it might be a thermostat sensor so i replaced it and nothing. So he then pulled my throttle body off cleaned it did the whole calibration thing or whatever its called that you have to do when unplugging them and it went back to normal!!! Well after a month (two weeks ago) its doing it again. Then he told me it might be that the throttle body has some condensation frozen and isn't allowing the throttle to open like it needs too.
I live in a suburb 20 minutes north of chicago and i don't drive the car if it snows, i keep it in my garage. I have a CAI installed on the car that i put on back in March of 09 and a flapper that i just permanently opened with an IV clamp. So i don't have any big modification on the car...yet
So I got a check engine light... did a scan and it said something about, "Cold Start Idle-Control System" and then it also has misfires on all of the cylinders and that it is running too lean.
I automatically went to check the intake, took it apart and the rubber coupler that connects the MAF sensor to the stage 2 pipe has a rip in it.
Now I'm freaking out thinking that maybe water... dust... dirt... has gotten into the engine.
I picked up my latest R back in April - 3 owner, 33K mile car - as far as I know no tune. The previous owner owned the car for the previous 9 years and kept it stock.
The issue: If the car sits for more than one day (I work form home so this happens a lot) upon initial start up it will start and idle at 800 RPM and then drop a little from there once warmed up. Now if the car sits for less than a day, it will cold start as it should - high idle then a gradual drop.
I've had my 2010 GTI for 8 months now and have really only had one issue with it. When I start the car, it shakes before I start moving. Like, the steering wheel, body, pedals, gearshift, etc... It's not a violent shake, but definitely something I've never noticed in any other car I've owned including my MkV GTI. It doesn't seem like a normal feeling for a brand new car. I took it back to my original dealer at 4,000 miles and they said there was nothing wrong with it and they didn't feel any vibrations.
Well lately it's been vibrating more intensely and more often (at almost 8,000 miles) It now does the same thing while stopped in traffic or at lights. It's really annoying to me. I took it a couple days ago to a new dealer (I moved) and just talked to them on the phone. They also said there's nothing wrong with it and it's normal.
I forget exactly what they said it was because I was walking to the gym, but basically it was some cooling pump/fan that kicks on to cool the engine down and that's what is causing the vibration. But, they said it's normal and all VWs do it. I'm not quite sure why a fan needs to cool a perfectly cold engine in the morning though.
I was going to post this in the technical forum, but going by the amount of replies, this forum seems to have much more traffic. Anyway, my car has random long crank issues. It usually happens when it is really cold or if the car has sat for a day or more. I will have to hold the key over for 5+ seconds, but as soon as I turn the key back and crank again, it fires right up.
I have replaced the battery and tested it and the alternator, replaced the CTS (green top), not that it's relevant, but I just replaced the thermostat, housing and all seals, no CEL. Any other things I can check?
It seems like it takes an awfully long time for the good mileage to get going from a cold start - even when it's warm outside. The last 5 miles of my commute are great, but the first 10 miles not so much. How much effect does ambient air temperature have on this process.
View 15 RepliesTried to start it, it just cranks for a long time, it can't even hold an idle. After 5 minutes of cranking and trying to get it running, it starts up just fine like there isn't even a problem. It just started to happen today. I have a 2004 v6 2.6 glx, completely stock.
View 3 RepliesI have a early 99 f250 super duty 7.3l and it's giving me fits. about a month ago the truck started to do a hot no start. drove truck for about a hour. Shut it off and half hour later no start. Let it sit over night and would start with long crank.
Changed CPS no change. Pulled tuner and set back to stock. No change.
Changed fuel filter, no change.
After reading forums changed IPR and truck started and ran great. About a week ago back to the same problem. Battery's are about 2 months old. Oil change and oil filter a month ago.
Checked the hpop reservoir and its 1/2 from the top.
Checked fuel bowl and it has fuel. no sign of oil in it.
Drained bowl and watch bowl fill back up. seems to fill quickly.
Pulled passside valve cover to check for bad orings while cranking.
Every thing seems fine. have not done driver side yet. used FORSCAN and ran buzzed test on injectors and they all buzzed what seems to be about the same. ran test couple of times to make sure. this morning I ran a live scan while cranking and this is what I got right before it started. ICP 660.6psi, IPR 64.84% and RPMs 227. took 8.86 seconds to start. after work scaned again for hot no start and this what I got. ICP 292.9psi, IPR 55.86%. and RPMS 203. unplug ICP and no change. still will not start. one thing I did notice when plugging ICP back in I looked down in side at the pins and can see what seems to be bubbling around one of the pins. the pig tail has just the slights sign of oil.
I "Bulletproofed" my f-250 Super-duty last summer and she ran great for a time, actually she is still running great, except for one thing that is driving me crazy. On a cold start it turns over until the oil pressure builds up. Then she will crank and runs fine, also starts normally after warm, turns over a couple of times and cranks.
I have oil in the filter housing, have replaced the seal at the bottom of it. Just pulled the oil rails off and replaced the seals on them, and a new IPR seal and filter. I am still having the problem, F.I.C.M. voltage has been fluctuating between 45 and 46 vdc. I have a P300 and P308 code.
I haven't really considered Injectors because it is idling smooth as silk and has great power.
How long do the glow plugs stay on during a cold start? Do the glow plugs stay on during the first few minutes of running?
View 1 RepliesWhat would cause my truck to have a long turnover start, a really rough idle, and a loss of power after idling at a stop light for about a minute?
This problem gets worse as the truck warms up. It feels as if I'm not getting power from all 6 cylinders but this goes away after about 20 feet of acceleration. The truck has never not started. It just has to turn over for about 5 to 10 seconds before it fires up. I changed the spark plugs and wires thinking it was that and then i tried the fuel filter and it wasn't that either.
I need to get my oil cooler replaced but that's besides the fact. I drove it on a little trip the other night ran fine. Then went to start it after i was done with what i was doing turned it over didn't start the first time. Cycled the key and cranked it again. Started up drove it back home on the high way no spitting or sputters got off the high way it started idling like crap and shaking as i accelerated but made it home. Let it sit over night and day (was at work) got home to start it and it fired up no problem but still idled funny.
Revved it a couple times and it seemed to clear up so i took it around the block. Floored it and it ran like it was suppose to then go to the other side of the block floored it again and it had no power and sounded like it was running on 4 cylinders. Pulled it back in the driveway idled weird and cleared up again went down the street and floored it ran like a scaled ape and then just died. tried cranking it over and nothing finally got it to start after holding the ignition on ran and then died again. Got it pushed home and decided to fire again after a VERY long crank and it idled for a couple minutes very horrible and died on its own and hasn't started since.
Check out how loud my cold start idle is. Still can't figure out why you can't hear the turbo on start up though. Even revving at idle you can't hear it that much. I've seen plenty of gti's with more exhaust restriction then i have and you can hear it clearly. [URL] .....
View 8 RepliesI have a 99 silverado with the 4.8 w/186k on the clock. I am having an issue with rough idle and hesitation on cold start up. Once the truck warms up the idle and hesitation go away. I have replaced the PCV valve hoping this fixed it, but it did not. I have also cleaned the TB and the MAF.
View 2 RepliesI have a 99 lesabre cold start rough idle but smooths out . Warm no start. Trouble codes P0171, P0300, P0336. Had plennum replaced 2 years ago but I'm seeing coolant around the base of the plennum so I'm going to have to do that again but I don't think that has anything to do with the warm no start.
View 14 RepliesUnless you manually hold throttle when cold jeep will stall. Once engine is warm all is fine. So what controls the high idle?
View 2 RepliesMy 2007 TrailBlazer with 84K stumbles for 25 seconds when I start up cold. After 25 seconds I hear a click and then it runs perfect. No engine codes present. Have new plugs, new O2 sensor, new thermostat.
View 5 RepliesI got the fuel pump and fuel pump control module replaced. Now I am still getting a cold start delay (5-10 seconds to start) and it has a rough idle sounding like its misfiring. This happened when i picked it up at the dealership after a new fuel pump BUT! keep in mind it has been doing this for a while so i figured it was the fuel pump.
New oem plugs and the coils were replaced when i bought the car because the coils failed during a test drive I need to scan the codes but i will post. Also this only happens during a cold start. if the car is warm and i go into target or something then start it shortly after its fine.
TSB'S I think will fix this. [URL] .....
I have a 2010 Elantra and noticed after I start it when it's cold the rpm is about 1800rpm but doesn't drop. I never really payed attention on this car but my other cars would drop after a minute or so. Is this normal on the elantra or is something wrong?
