Sonata NF (2006-10) :: High Rpm Cold Start / Engine Is Knocking
Recently, our 2009 Sonata jumps to relatively high and not normal RPM when start cold (and I don't mean winter-cold; I mean first start in the morning). It jumps to around 2500 rpm for 3-4 seconds before it goes down to the normal 1200-1300 or so for a cold start.
Also, not sure if this is the normal Sonata engine sound, but when we push the accelerator it sounds like the engine is knocking, almost like a whistle of fuel flowing.
Volvo - 240 :: Engine Idles High For 3 To 5 Seconds And Then Immediately Dies On Cold Start
A minor but persistent (year-long) rough idle on my 1991 240 has quickly turned into a Cold Start Nightmare over the past month:
SITTING HOURS OVERNIGHT (50 to 60-degree temp. overnight) - When I attempt to start in the morning, the engine idles high for 3-5 seconds and then immediately dies. To successfully start, I must keep pressing the accelerator pedal at least half-way down for 2-3 minutes. The engine sputters, almost backfires, shakes, lopes, almost dies, etc. After 2-3 minutes, everything runs just fine.
WARM ENGINE SITTING - Once the engine is warmed up, it will consistently start without problems. Still a slightly rough idle, but OK. The car does not die.
I have changed the battery, coolant temp. sensor, and spark plug wires.
Civic - Honda :: 1997 - Dash Lights Comes On / Get High Pitched Noises From Engine But No Start
Parked my Honda Civic (1997 stick shift) in driveway at a slight forward downward slant. Two days later it wouldn't start: dash lights come on, get high pitched noises from engine but no start. Tried for 2 days, same results. Ambient temp is in 60's. Had routine service 2 weeks ago and it was running fine.
Tow truck driver tried it, got same results. Had it towed a mile to mechanic (front end elevated while towing). Mechanic called to say it started on first try for him but seemed to be running rough. He checked it over and now has come up with 2 or 3 things it may be but isn't really sure.
Mechanic Is going to replace the ECP (?) to start with but is going to be going at it one part at a time.
Cherokee :: 1999 V6 - No High Idle With Cold Start
Unless you manually hold throttle when cold jeep will stall. Once engine is warm all is fine. So what controls the high idle?
View 2 RepliesGolf IV R32 :: High Pitched Noise On Cold Start
It's been pretty cold here and haven't started my R in 2 days at the most. I turned it over this morning and got this high pitched noise, like maybe a belt slipping or a bad bearing? The CEL flashed a few times then went away.
I couldn't stick around to check codes or inspect the bay, but what it might be?

I have a 2000 Honda accord and in the cold it has a hard time starting. It will turn over but it is like it is not starting right away. I also notice there are times when it starts to turn over but then it dies out.
View 2 RepliesCivic - Honda :: 2003 - Hesitate Once Or Twice After Cold Start
I have a 2003 civic (automatic) with 72000 miles on it. It recently began hesitating from a cold start. It will hesitate once or twice, I stop, and after that it is fine for the rest of the drive. Since it is sporadic, it's hard for the mechanics to see what is going on. I took it to one mechanic who cleaned the fuel injectors, cleaned the throttle plates, flushed the transmission fluid, and replaced the spark plugs. He also put a note on the bill that the transmission may need to be rebuilt soon, although he didn't mention that when he told us what he did. The car drove fine for about three weeks after that, and then it started hesitating daily.
I took it into another mechanic who was able to see the problem for himself when I left the car overnight. He scanned it for error codes, but didn't find anything. He said he checked all connections and wiring and cleaned the wiring but that was all he could do. He said he thought it was a bad O2 sensor, but because the check engine light isn't on, he can't do anything. Meanwhile, he said I should keep driving it in hopes that it will get worse so they can figure it out. I'm worried that I may be causing long term damage, and that I may get stuck in the middle of an intersection without power. Is there anything they didn't check that they should have? Should I take it to another mechanic?
Civic - Honda :: Low Rumbling Noise At Cold Start
So for the last week my Civic has been making a low, rumbling sound (almost like an overly powerful bass system or a muffler) and vibrating whenever the car is idling from a cold start. The noise is most pronounced when the car is started but continues for a short time while I am driving, but only when I take my foot off of the gas in low RPM (below 1.0k). Whenever I accelerate, the noise stops, but when I go in reverse the noise is becomes louder. Also, the noise is very faint from outside of the car, but very pronounced from inside. After about 20-30 minutes of driving it usually goes away. What could be causing this?

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.
View 2 RepliesCivic - Honda :: 2002 - Cold Weather / No Start
I have a manual transmission 2002 Honda Civic. Recently when the nights started getting cooler 20's and 30's, my car will not start. The starter will not grind or even click like it's trying to start. All the other electronic devices seem to operate normally, dome lights, head lights, dash lights, radio. Replaced the battery thinking it was the problem. No difference. If I turn the headlights on for a few seconds, the car starts fine. If the temperature is in the 40's the car starts without any problems. The car can sit for days without activities, as long as the temperature seems to be above about 40 degrees there is no problem. As soon as the temperature goes down, the car doesn't want to start again. I was thinking it may be the alternator not recharging the battery enough to give me my cold cranking amps, but before I dig into that mess, Are there places I can take my alternator to and have it tested to see if it is the problem?

View 12 RepliesGolf IV R32 :: Cold Start As It Should - High Idle Then A Gradual Drop
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.

My daughter owns a 1992 Honda Accord wagon, she cannot get it to start on colder days. Sometimes she goes out and runs a hair dryer over the engine, it works, but it is getting worse. Her husband says that is ridiculous to do.
View 2 RepliesCivic - Honda :: 2002 - Hard To Start In Cold Weather
My 2002 Honda Civic (160k+ miles, manual transmission) has twice failed to start this winter. This happened when the temperature is cold (<32 Deg. F). The car came with me from CA to the East coast (mid Atlantic) about 5 years ago. It occasionally has been difficult to start it in cold weather since moving East but otherwise it starts first attempt without issues.
This morning it barely started. This evening, it didn't start using the ignition. Turning the key, the engine attempted to turn over once perhaps twice. After several attempts the engine did not turn over at all - no detectable sound from the starter motor, instrument lights will flash and clicking noises come from the dash. Attempting to jump the battery with another vehicle had no effect - the engine would not turn over at all, the instrument lights flash, clicking from the dash. The battery health indicator is green.
I did get the car started by coasting down a grade, putting the car in gear to turn the engine over, and then using the ignition (I must depress the clutch to use the ignition but getting the engine turning worked first attempt without issue).
After arriving home and shutting off the engine, the car will start on the first attempt without issue (even after letting it sit at 25 Deg. F for 3+ hours). This seems like a mechanical issue and the starter motor is an obvious place to start. I can double check the battery connections and do some basic electrical testing, how to verify the electrical grounding (I'm handy with a multi meter).
Lexus RC F 2015+ :: High-Pitched Whine Below 1200 Rpm After Cold Start?
I posted a related video in the fuel pump thread here where the high whine noise is apparent several seconds after a cold start. Now from inside the cabin, looking at the revs, the "sewing-machine-like" whine disappears above 1200 rpm.

Sonata NF (2006-10) :: High Idle Speed About 1200 RPM On Cold Start
Bought my 2006, V6, about 2 months ago. This morning was the first really cold once since I bought the care. When I started it today, the idle speed was about 1200 RPM. It took a few minutes to warm up and then the idle speed dropped to normal. Quick question. Is this normal?
View 1 RepliesPassat (B5) :: Loud High Pitch Noise From The Motor On Cold Start Up
Every morning for the last 3 days I've gone to go warm up my car and each time i turn on the car only from a cold start up i hear this loud high pitch noise from the motor. If i turn the car off and restart it. It goes away and the car is at perfect idle. what is this and do i have some serious problems?
Is this true? If it's only on a cold start up, and then it goes away during normal driving, you have no need to fear....that's the Secondary Air Injection Pump that turns on during cold starts, and the plastic hose just needs to be replaced.. If so where is it located so i can replace this hose.
