Lexus SC430 :: Initial Idle RPM At Start Up
Nov 16, 2015
When starting your SC on let's say a day where the temperature is 35 - 55 degrees, what is your initial idle RPM?
Next, how long does it take to settle down to a lower RPM and what is lower RPM when the car is still in Park?
Lastly, can tapping the gas pedal after initial start-up bring the idle RPM down while the car is in Park?

My '06 SC has about 72k miles and I've notice of late after starting it, it initially idles at about 1,200 RPM and tends to stay there until after driving and warmed up and then goes down. It used to start up at 1,200 RPM and after a very brief period of time would settle at 1,000 or 800 RPM, I can't recall exactly. My question is, is this normal related to the life of the engine, or do I have a sensor or other type of issue that can be addressed.

So, I have Stoptech rotors and brakes, and it squeals when (a) it's warm after a few minutes of driving and (2) only when I initiate braking softly to slow down, but disappears after braking firmly to stop. Brake pads have about 80% left on them.

I have an issue with extreme high initial idle at start up. I took my 1998 Ranger with a 3.0L to the local dealer to have some work done about a month ago. Long story short, my number six plug wire got burned against the exhaust rail.
Anyway, I guess they re-flashed the computer to the newest *.bin, or flash version. After that when I start the truck the tachometer jumps up to 2200 - 2300 RPM and then it settles down to about 1500 after a moment or two, then it finally adjusts itself to about 1100 for a few more seconds and eventually ends up at 900 - 1000 RPM.
I confronted Ford about this and they said that Ranger's and F-150's do have a tendency to do that at start up. Ordinarily I wouldn't be too concerned, however I believe that the 2200 - 2300 RPM high idle at start up at 0 F, a bit much.

Any way to disable the initial start up screen on a 2013+ that tells you "Drive safely and obey traffic rules....." then has a "continue" button to select?

Idle is good in gear without load but if i turn on the AC or the headlamps the idle speed increases slightly but is not as smooth ...very weird...

I have done hours of searching about the rough idle on the SC430. What I haven't been able to find is any information about an intermittent rough idle. I have cleaned my MAF sensor twice.
I am having my mechanic replace the radiator tomorrow because of a leak and he is also replacing the idler pulley and the belt tensioner (one of them is making a noise and I purchased an extended warranty!) At the same time he will be doing a throttle body cleaning. I had my timing belt replaced as well as the water pump and had my mechanic check all the spark plugs and all were fine.
I am going to have him check the motor mounts as well. The RPM's are fine with the AC on or off and I have used Lucas fuel treatment on this current tank of gas without any results and my next tank I will try Seafoam as suggested by my mechanic.

I took my car to a mechanic the other day to get the spark plugs change. Then I notice when I turn my car on my seats starts to vibrate when in idle. Is this normal cuz the mechanic says this is normal and that every car vibrates just a little. I read some where it could be the mounts but someone on here told me they not because it doesn't shake my seats just vibrates if I seat there I can feel the seats vibrating on and off its not crazy bad vibrate. It's a minor vibration. I was hoping for no vibration what so ever like sitting in on my leather couch in my living room. Mine is a old model 2002.

Noticed a slight vibration from my engine at idle. Nothing too overbearing but just had a concern. How much should I expect if the engine mounts need replacement? Parts? Labor?

I hope I didn't just happen to notice this today if it has been going on for any length of time now. I started up our '05 this morning and she's definitely whirring at idle. I do not recall hearing this sound at all recently and we've been on a couple lengthy trips with it. Fluid levels all appear normal.
Had my wife start it up too and she agreed that the whirring was not there previously. What are the most likely candidates into which I should look first? It' not high pitched, but a steady muted whir of the type I might expect to hear when two gears spin while making contact.

I have a 2003 SC430 with 170,000 miles on the odo. When at idle, the car shakes a little. I notice it the most when at a red light. But if I put the car in N, the shaking goes away. It happens with the most severity when in D and with my foot on the brake. I'm assuming the shake is normal for a car of this age and mileage, but i'd like to eliminate it.

1) Where to find a driver's lower fuse panel in cabin fuse cover/kick space left side, near brake?
2) I have a slight intermittent magic fingers kind of idle. I changed spark plugs, no diff, have been using Techron, timing belt replaced, etc.

I have recently had my motor mounts and transmission mount replaced.
Before the replacement, the car would shake quite noticeably when the engine was being started (maybe even shake 'violently'). I thought this was normal until I had my motor mounts and transmission mount replaced. Now when I start the engine the SC430 doesn't shake at all. The difference is profound.
Just a head's up. I'm not sure what the implications are of running with bad motor mounts for a long time, but I decided to get it done because my car would shake when idle and at stop lights.

I am having problems with my Prius. I have a 2011 prius with 145000 miles. I also have issues with the engine shakes initial idle and goes away with check engine light saying 2 & 4 misfire. Also I had a couple off issues where I was at a dead stop and when I accelerate the engine would feel like it Boggs and shakes from 0-20 mph then go away after. From 20-80 mph it's perfectly fine.

I have a 2001 Jeep Cherokee Sport edition, automatic transmission, about 100k miles. Recently, when I turn on the engine -- sometimes -- it is very loud, and the car really shakes back and forth (in place) with the engine. It almost feels like the car is going to die. It feels like a very bad idle. If I wait, nothing changes. If I turn the car off, wait, and turn it back on, nothing changes. If I hit the gas, it continues, but decreases very quickly and by the time I hit a stop sign or red light (let's say 100 yards away), the car is more or less fine; no more fear that it's going to die, although there's still some noise that seems like it's coming from somewhere between the transmission and engine. I had the starter replaced last June (when it went kaput) and replaced the idle control valve a couple of months ago (the car kept dying when I came to a complete stop). I mainly drive it to/from work, about 50 miles each way, going 45-80 mph on a hilly freeway, and there have been no problems while driving.

I am stationed in Europe at the moment and my wife has been driving my car.
She last drove it a week ago and when she got in to drive last night it would not start - Not even a "click". Interior lights worked, radio etc.
Could be the battery of course with not enough voltage threshold to even engage starter solenoid.
But I was looking for other things she could check before I come back in 3 weeks. I will deal with a battery replacement then if required.
She confirmed car is in "park".

Just disconnected battery to give a full charge because car sat for the winter and hood was propped open which killed the battery. Meanwhile I reconnected the battery and only the lights will come on. The car will not start with key in ignition. Don't know if there is a security issue or just what.

When I start my 2003 SC430 I hear this screeching noise. It sounds like it is coming out of the dash but it may be under the hood because my neighbor heard it outside the car.

I have a 2003 430 with 110K miles. Car would not start this morning. It cranks so it appears the battery and starter are fine. Battery was changed last winter. I had the timing belt changed at 80k. Its been a great car with very little problems.

I replaced my headlight today, was really hard but I got it done. To my surprise, when I went to start my car it turned over then died. A gas smelled followed with a slight hissing. I also worked on my intake today because there was a leak, but I don't see how that's related? Maybe a fuel pump relay? She doesn't seem like she is getting fuel and dies!

I had to replace the ECU on my 2002 sc430. Although the original ECU was malfunctioningthe car started and was drivable (but the speedometer and odometer did not work, nor did the power steering). Following installing a used ECU, the car will now not start. I reset the ECU following the directions posted by others in this forum (both the gas pedal method and removing the fuses), but that has not fixed the problem. Do I need to have the dealer sync the key to the new ECU?
