Lexus SC430 :: Initial Idle RPM At Start Up
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?
Lexus SC430 :: 2003 - Air / Blower Running More Frequently Than Usual
2003 with about 140k miles, radiator was replaced a couple years back, recently replaced timing belt (#2) and some valve cover gaskets in advance of a road trip.
On the road trip, used no cooling air, occasionally used heat at night with the roof down. At one point, I thought I heard my engine louder than normal, but decided it was actually machinery nearby.
The next morning, after only about 1 hour of leisurely driving through a civil war park for about an hour, I confirmed that in fact it was my vehicle making the noise.
It was fairly frequent, and basically sounds and feels (hand on air filter) like the blower kicking on, as if to cool the car off.
But the air temp was cool, the car temp was solid and cool, so there wasn't a good reason for this to be happening.
Because I had just had the timing belt & such done, I stopped at a dealer. The engine light came on as I pulled in.
They indicated that they saw a MAF sensor failure, and that while it needed to be replaced, it wasn't a problem to finish my road trip. They indicated the check engine light was related and also ok to drive with. They then lost a lot of credibility when they tried to ask me if perhaps the AM radio was the noise I was hearing...
Despite that, I continued on (had to be somewhere and they said it was ok to drive). The engine light actually went off the next time I filled up, so I decided perhaps that was actually a gas cap pressure issue (saw that once before in my ~6 years of driving the car).
Back at my home Toyota shop, they confirmed the MAF replacement need, and have also suggested spark plugs (fair enough).
But re: the air, they don't believe it sounds 'wrong'. I agree with that- it sounds 'right', as in when the blower kicks on, and I vaguely recall that it was something I heard back when my radiator actually rusted out / failed.
My issue is that it seems to be happening MUCH more frequently than normal.
So while I don't recall hearing it at all over the past couple years or only on very rare occasions under load, or when the radiator failed, it seems to be almost routine now, where at a given stop light (even in just a few miles of driving in town at low speeds), I'll hear the extra noise.
Lexus SC430 :: Brake Noise / Squeal During Initial Deceleration
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.

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 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.

Sometimes when I stand at idle, the engine seems to vibrate more than usual. I looked at the RPM gauge and it didn't move at all, it's at roughly 1000-1100 RPM when it occurs. Is it something I should show to the dealer?

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 recently started noticing that my engine sounds louder and rougher than usual. I have a 2014 GX with about 25K on it. I get about 800-900rpm on idle and about 1800-1900 when cruising 70-75 mph.
Engine sounding louder all of a sudden. No "check engine" sign pops up. I also took the car to the dealer and mechanic rode with me on surface streets and of course , everything looked normal to him.

View 7 RepliesLexus SC430 :: Intermittent Rough Idle
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.
Lexus SC430 :: Seat Vibration When In Idle
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.

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.

Lexus SC430 :: Shakes When Idle And At Stop Lights - New Motor Mounts?
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.
Jeep - Cherokee :: 2001 - Very Bumpy Initial Idle / Car Shake Back And Forth
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.

Yesterday my mom used my car and the battery light came on while driving, but she didn't really care about it and was driving the whole time on the battery. When she came back home the car was barely even alive I couldn't even start it. I replaced the alternator (duralast from auto zone) and the serpentine belt, but now I have a very rough idle and the rpm's are lower than usual. They are 1500 instead of 1750. Is this normal and eventually it'll go away or did I mess something up?

View 7 RepliesFord Fuel System :: 1998 - Extreme High Initial Idle At Start Up
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.
