Lexus RX 2004-09 :: 05 RX330 Starts Pinging At Part / Light Throttle Once Engine Fully Warmed Up

My wife's RX is really starting to give me a headache. The first problem I'm having with this car is detonation. The car starts pinging at part/ light throttle once the engine is fully warmed up. The is no CEL or codes pending. After scanning the car it seems that fueling is right where it should be and nothing else seems out of order. The pinging stops when you hit the gas harder. So far the only way to rid the car of this problem is to fill with 93 octane and that gets expensive with a daily driver. Shouldn't the knock sensors be handling this? Is there a way to test them?

The second problem I have is the heat won't turn off. Hot air always comes out at what seems to be low fan. I can move the area it comes from ( dash vent, floor etc) but I can't turn it off. With the fan set to off and no settings chosen I still get heat.

The car currently has 78k miles on it

Golf IV R32 :: Misfiring At Part Throttle Whether Car Is In Gear Or Sitting

Getting a misfire at part throttle. Whether the car is in gear or sitting. At idle there is no misfire, and at WOT there is no misfire. But if you hold the throttle part way (like when trying to cruise) you immediately see the misfire count go through the roof on vag-com. this can be duplicated in the garage by holding the idle to 1500-2k with no load on the motor.

4 codes, which come back immediately at part throttle as described above.

multiple cylinder misfires
cylinder 1 misfire
cylinder 2 ""
cylinder 3 ""

tried moving plugs and coils with no change, problem stayed on first 3 cylinders
checked t-body readings and appears to be aligned ok
checked maf readings and appear to be ok
found one questionable vacuum line and replaced it, no change.
checked vag-com fuel trims and they showed -4.7% which appears to be with in the acceptable 5% range
watching lamda on both front O2 sensors and they seem to be following the same trend.

When I look at measuring blocks 26/27 it shows me knock sensor signal on all six cylinders, and 1-3 are much lower than 4-6. This is the only discrepancy I have located, and not sure if it is the cause or an effect of the problem. I checked the knock sensor (located below exhaust manifold on passenger side) and the sensor and wiring appear good. I checked resistance best I could and it appears in spec (infinite resistance) but the pins are so small and the spec is so vague I am not 100% on the results.

I have vag-com and a full shop access, but no R32 specific bentley unfortunately. I only have the older (up to 2002 I think) MK4 manual but that only covers the 12v. Looking for the wiring diagrams for the coils or knock sensor harness'...

Camry :: Steering Wheel Flutter And Humming Sound

A few months back my 2007 Camry started having this vibration along with a humming/buzzing sound between the speeds of 40-70mph. I seriously thought it was an axle/hub/bearing issue because of the buzzing sound. But at the same time the brakes were wearing down and noticed the shaking of the rotors when braking so kind of figured it may just be that. Explained to the Toyota people and they said most likely new brake service will fix the issue and not an axle/bearing issue. So went ahead and had the brake service done for both front & rear but the vibration & sound is still there. Can't be the tires because just got new ones just last year. Balanced & alignment done and still doesn't solve the problem. Found a TSB, T-SB-0106-08: Steering Wheel Flutter/Body Vibration at highway speeds (approximately 65-75mph).

I have a 07 prius with 60k Km. right now, everytime i go thru a hole, there is always a noise like something is loose. It also sounds like a rattles too. The noise seems to came from the front driver side tire (i have the right side driver japan version prius ). I assume it was the shocks / struts that needs replacement.

Ford F-150 (2004-2008) :: Odd Screeching Sound Under Relatively Heavy Throttle - Driveshaft?

I have an F-150 Heritage 4.2L V6 Manual 4X4 and over the last few weeks have notice a couple of odd things. First I noted an odd screeching sound, similar to a rock caught in the break drum, but it seemed to be coming from under the cab/bed, not a tire. It only seemed to show up under relatively heavy throttle, which I thought was odd. I went through a car wash with a good under carriage spray, and the sound went away.

A few days later it snowed and the sound returned. I don't know that it's actually related...but that's how the weather went... Now, when I let off the throttle and the engine holds the truck back there is a "thump", and when I reapply the throttle, it thumps again. If I press the clutch in first, then release the throttle there is no thump; so I assume this is something with the drive shaft.

I climbed underneath and found that I do have some play in the shaft, I can twist it a tiny bit so I know that I have play in the shaft which (and I am NO mechanic) I assume is not normal. I can see the shaft turning all the way to where it goes into the back of the transmission so I assume the play is coming from the rear yoke?

I thought I could replace the yoke relatively cheaply but I keep stumbling across posts indicating that with this particular set up, I actually have to replace the whole drive shaft. What I could be looking at, and what my options are?

Prius (2010-12) :: Windows Loose In Their Tracks / Flutter When Lowered

I'm sure that this is not normal, but I just want to know if any one else has this problem with their car. When the windows are down, they are loose in their tracks -- you can actually shift them forward and backward with your fingers. Also, if the windows are lowered when I shut the door, the windows flutter. The right rear window is so loose, that it creaks when I hit a bump even when the window is all the way up. The windows seal up just fine -- no wind noise or leaks of any sort.

In the link below you can see me shifting the windows forward and back. The right front window is least affected, right rear is the worst, and the two left windows seem about the same.

Prius (2004-09) :: 2006 - Oil In Throttle Body Area

Just purchased one of the members 2006 Prius. It wasn't in good condition and I knew that upfront. The price I paid justified the imperfections on the car. The car has 117k miles and it does burn oil. To the tune of 1 qt every 3000 miles according to the seller. However I believe it burns more than that amount now. I changed the oil and the dipstick reading was slightly below the minimum mark. The engine doesn't sound all that great but seems to run very well.

I was cleaning the throttle body today and noticed there is oil in that area. I looked down the throttle plate (not sure what that's called), and there was a layer of oil on the bottom. I know oil is not suppose to be in that area. What could this be?

The car had a leaking ice water pump and the coolant was a bit low, not sure if it could have overheated before.

Prius (2004-09) :: Orange Dashlight Flashes When Releasing The Throttle?

I have, on several occasions seen an orange light flash to the right of the speedometer when releasing the throttle abruptly.

I cannot reproduce this, but it only happens when it's wet (so far).

I think it *might* be the skidding-light, it is about that location in the dash, but it flashes too short to be certain. And it wouldn't make much sense, there should not be enough friction to stop the wheel rotating, should there?

Ford - Explorer :: 1998 - Sputtering Sound Coming From Lower Part Of Engine Compartment

I just got a new clutch and clutch slave cylinder in my 1998 Ford Explorer. Driving it home from the mechanic, I'm hearing a sputtering sound coming from what seems to be the lower part of the engine compartment. It sounds like a VW Bug exhaust. I've never heard this sound before. It's troubling that it has appeared now immediately following a repair. I presume there is a outside possibility that it's not the mechanics doing, but that seems improbable. (The engine was revving high right before the clutch blew out last week, so maybe those brief high revs caused some damage? I can't imagine that being the case.) Or was there something in the clutch repair process that could have resulted in this?

I made a recording of the sound here.......

Prius (2004-09) :: 2006 128K - Error P0A08 / Throttle Has Been Hesitating On Acceleration

I got the Check Engine/VSC/Triangle of Death errors yesterday. Autozone reports it is P0A80 (replace Hybrid battery) though no additional details reported.

I'm the original owner, and after some reading suspect it could be something else because:

1. In 8 years, the starter battery has never been replaced.

2. For about two months, the throttle has been hesitating when first accelerating (within first five minutes of turning it on). Yes, it is the hot summer months (though mild compared to previous summers). And the hesitation occurs even in the morning before things really heat up. This is definitely even worse after the error lights came on.

I've seen recommendations to replace the starter battery first. And other recommendations for "throttle body cleaning." I'm not a mechanic, but obviously would hate to have the hybrid pack replaced if it is something else.
