Corolla :: 2000 - Slight RPM Drop During Cold Weather
Sep 18, 2013
I have a 2000 Corolla CE with 51k miles (bought a couple of months ago).
It ran perfectly during the hot weather (75-80F) and it idles around 650rpm-670rpm. These couple of weeks, there have been very cold weather (60-70F) and it idles mostly around 650rpm but can drop to 630-640rpm. Sometimes, it will suddenly drop to around 612rpm (there will be a very slight shudder) and pick back up to 630rpm. This is with all accessories turned off.
If I turn on the windshield wiper, then every time it activates, it drops to around 612rpm and picks back up quickly. This only happens during cold weather.
I don't think it's the MAF sensor.. what it could be?

the car 07 passat wagon fsi auto value edition.. This is my first winter in Maine and I've noticed by 35 degrees F and colder when vehicle is at operating temp and then I use the cabin blower say 72 degrees or hotter on fan speed 2; causes engine temp to drop maybe 10-15 degrees. Car reaches operating temp quickly! And coolant concentration seems right!

Having this issue? Should I have it look at? Or is this normal?

When it is cold out or wet my serpentine belt squeals a lot or a couple of minutes. It had progressively gotten worse this past winter. The shop said the belt looks fine and Toyota wants me to pay for them to look at it...

have an 2009 Toyota Corolla 62K miles. If the car sits out 8 hours or more in VERY COLD (zero degrees) weather makes a 1-2 second clashing/sparking noise the split second after turning the ignition on but before engine starts. I tried to attach video/audio. The car starts and runs fine. isn't a ticking or knocking or tapping noise assoc. with bad engine. It isn't squealing noise assoc. w/ serpentine belt. I've been waiting for it to get cold enough to leave overnight at Toyota dealer. I keep wondering if it isn't related to the botched oil changed at the Toyota dealer a couple yrs ago when they forgot the oil & I ran car about 30-60 seconds. At the time, they said all was okay and did compression test (Cyl 1=178psi, #2=175 #3=180 #4=178) all within the normal specs 145-189. I got a 2nd opinion at another Toyota dealer at time who removed valve cover and inspected cam caps and scoped cylinder walls and said all was okay and compression good. No mechanical problems- uses no oil, check engine light not on, etc. What noise is and why just when very cold and car sits out long time?

First, it's not a sticky IAC. I already experience that in cold weather and compensate simply with the gas pedal until engine warms up. However this coughing, sputtering, backfiring, misfiring problem is very severe. When it is in this state, the engine will lose rpm and stall. No way to coax it with the gas pedal to keep it running.
It happens most often when you restart the engine after having stopped somewhere for 10-30 minutes. It happens less often during a cold start in the morning. When it does this, I remove the key, and try again. Usually in 3-10 tries, the engine runs properly. Once running properly, there is never an occurrence of this.
However, today only, first cold start, it cranked and would not fire at all. Repeatedly. Jiggled the key and maybe they made it start. Ignition switch? If Neutral Switch, it should not have cranked. Perhaps my intermittent problem is worsening.
Wet weather seems to aggravate it.

Title pretty much says it. When its COLD it surges while idling upon start up. It goes away once you start driving it and the engine warms up. Other than that it runs great. Its got about 235 K with a replacement motor that has about 100k. I've had it about a year. Great vehicle. Its a standard.

I am writing this about my fiances 2000 Oldsmobile Alero 3.4 liter. I live in MN so we see our fair share of cold weather. After her car has sat over night it will not start in the morning when the temp is below 32F or so. It started happening at the end of last winter and then it got warmer out and the car became normal...which is hard to figure out the issue when you cant verify the problem when you want to. Anyways we just had one of our first pretty cold nights and we went out to start her car and it barely started.
I have suspected it to be a fuel issue because while trying to start it if I hold the gas pedal in it will start to backfire lately and just acts like it is flooded. This last summer I looked over some things and found that the Fuel Pressure Regulator was leaking into the vacuum line which would go into the intake manifold and flood the car. So I replaced that convinced that it would solve the issue. It didn't. I also found that the PCV valve was stuck so I replaced that. Last winter I dumped in a bottle of gasoline de-icer or whatever that stuff is called thinking maybe she got some bad gas and her lines were freezing. That didnt change anything.
When the car wont start I can literally crank until the battery is dead (newer battery in the car) with no luck. I have had to be jumping it and cranking it over for a good hour to get it to start. Not cranking straight time obviously. But about an hour worth of time before it starts. And at that time i am thinking it starts just because of the air temp going up in that amount of time or something... I don't know. I am not quite ready to bring the car into the shop because I know it will need to stay there for a few days to be able to get the right conditions for them to verify the problem. My fiance and me have very busy schedules between both working full time and going to school full time. So to be without a car for a few times isn't an option.

2000 Sierra 1500, 5.3L engine. When he starts it in the cold (below 40 degrees) at first hits 1000rpm, then immediately drops to 400-500rpm. The idle is rough and wants to die if he tries to drive it. However after 10-15 minutes and the eng warms up, its fine no problems at all. There is no codes, so the scanner we had didn't tell us anything. He had cleaned the TB and intake system with cleaner, no dice. He also disconnected the IAC while it was idling rough, that didn't change the way it ran at all. We would like to toubleshoot it more before we start throwing parts at it.

So my wife drove her car all day yesterday, everything fine. This morning went to start and it wouldn't. It turns over fine just not firing.
Now during the summer I had replace the fuel pump/filter before discovering that was not the issue.
I know you are already thinking CPS!.. I replaced that over the summer.
I have not checked the spark yet, kinda hard to do that one by yourself.
Beyond spark I am not sure what else could be wrong, especially because it was running fine last night. Is it common for accents to have issues in 20 degree weather?

Fuel pump does not work in Cold Weather, but works fine in warm weather? Will replacing the pump solve this or is there a bad sensor somewhere else causing the problem?

I have a 2000 Corolla CE I bought recently that had 45K miles on it (it has a 4spd auto with O/D).
When accelerating from a stop, I usually take it very slow and I notice that there is a slight jerk most of the time.....it's sort of like I can feel the gears engage. This doesn't happen all the time and it doesn't seem to happen if I accelerate fast.
I did a transmission drain & fill with Royal Purple MaxATF (the drain & fill was only once).
1) Is this normal for this transmission? Also, is there a "pan drop" for this transmission? The mechanic only removed the drain bolt...he did not do the pan drop.
2) During my work commute, I'm in a lot of rush hour traffic where it moves for short distances at 5-10mph. It will shift from 1st to 2nd a lot of times...is better to just put the car in 1st (L) gear? My mechanic said no because it will heat up the transmission faster.

My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...
-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.
However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.
When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.

A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.
She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.

I have had some slight rough running with a cold engine and stumble <2000rpm. Finally it tripped a CEL which was read as a misfire code.
The mechanic swapped the coil and plug(recent) and no change. He did a compression test and air blew out the exhaust. So.......the car needs a valve job which entails motor removal and fixing the head and reinstall. He rough estimates this at $2000 and rate is $65/hr.
He mentioned looking at pistons and may be a bit more if rough.

When the temperatures drop to the single digits and below, my car won't start. It won't even turn over! I turn the key and there's nothing. So, I sit in the car and then turn the key again. I wait. Then turn the key again. Within about 5-10 minutes, the car starts and its good to go! I've had a new battery installed. And even with the new battery, it does the same thing. At the shop, they check the battery and say it's fine.

Just noticed today that I have a slight drop in boost. Normal boost is 1.5 bar but today it is running slightly lower boost and does not have the same pull through all the gears.

99 Dodge Ram 1500 Automatic 5.2L. Whenever I come up to even a slight hill the A/C will stop blowing and the vehicle speed will drop 3-5 mph and stay until after the top of the hill and will be sluggish to regain speed and A/C will blow again once original speed is achieved. No engine light or warning lights come on. What could be causing this problem?

We purchased a new LaCrosse CXL in 2005. Its speedometer now shows 90,126 miles. The 5W-30 motor oil has been changed every 3,000 miles with no indication of oil loss until around 65,000 miles, when I began noticing a slight drop in oil level on the dipstick (about 1/4 quart) within the 1st 1,000miles following the scheduled oil changes. I then added enough oil to bring the oil level back to full. Within the next 1,000 miles, the oil level again shows oil loss of about 1/4 quart. This has continued over the last 4 years. The car is garaged, and I have never seen any sign of an oil leak on the floor. I have alsodriven behind the car several times, and have never seen any sign of oil smoke coming out of the exhaust pipe. Both my Buick dealer and oil-change shop manager can offer no explanation as to why this oil leakage problem developed and continues. The oil shop manager says he has other Buick customers with the 3800 V-6 engine that complain about this same problem of engine oil loss.There have been no mechanical problems with the car and with the exception of the oil "leak" we have been well pleased with the car. Where is the oil going?

When your car is idling the rpms drop below 600rpm and you can feel like its going to stall but then goes normal. How do i fix this? Clean throttle body???
Also how hard is it to change the transmission fluid? Possible to do it at home?
