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/GTI VI :: 2003 1.8t Pre-Detonation When Boost Over 9 Psi
I have a 2003 jetta 1.8 turbo with a APR chip boosting 21 psi. I have had no problems for the first 5 years or so, but then recently within the last year it started predetonating when I boost over 9 psi, I've tried replacing the injectors, upping the fuel pressure, using 93 octane fuel, (which I always had used anyways) replacing the oxygen sensor and other things to no avail. Also there are no codes regarding this issue stored in the computer.
I highly doubt there is any issues with carbon buildup in the pistons.
Lexus IS 2014+ :: Transmission Is Slipping When Changing From 3-4-5 Under Light Throttle
While driving around with the 8 speed is350, It seems like the transmission is slipping when changing from 3-4-5 under light throttle. The revs shoot up and then it finds the next gear kind of like someone riding the clutch in a manual car.
This used to happen a little during the winter on cold start but its happening more often even in warm weather. Maybe I'm just crazy but I'm sure its not supposed to be acting this way.
Lexus RX 2004-09 :: Throttle Power Is Very Low - Code P2121
I have a 2004 RX330 around 110k miles. My wife was driving home the other day and check engine light, VSC and Trac Off lights all came on and throttle power is very low. Can barely get RPM to 2000 or 3000 rpms. I googled the code (P2121) and it said to replace Accelerator Pedal Sensor (Gas pedal). I removed cleaned the throttle body and installed new pedal and still have lights on and won't get up to 3000 rpms. How do I reset the lights? I have had both battery cables off for an hour and it won't clear the memory. Radio still has presets, but windows and memory seats have lost memory. What I should do next?

Bought a 2013, had been in a flood, couldn't see any sign anywhere of water level or damage, had 12,400 miles and noticed engine ping/detonation when engine lugs, have changed to mid grade and that works but every time I go back to 87 octane it starts back up.....also, I have noticed a bog down of the engine when I just barely give it any gas and if I keep the accelerator in that exact same spot, it eventually jumps into like a surge...
View 5 RepliesFord Ranger / B-Series :: 1997 - No Power - Detonation - Misfires?
Posting this on behalf a friend. He has a '97 Ranger 2.3, 5 speed, 2WD, no A/C or power steering. No trouble codes.
The Problems:
It has an erratic random misfire at idle. Just runs very rough at idle. The misfiring goes away once the engine speed is up.
It has absolutely no power while driving, it's foot the floor all the time. On a straight piece of road it will top out at around 65-70 MPH. Above ~2700 RPM or so and it will start getting severe detonation, by 4000 it's really bad.
Along with the no power issue, it also does not like to rev. 4300-4500 RPM is about the end of the world for this thing, and it really does not want to spin any faster in any gear. It just stops pulling.
What we've done and checked: Complete tune up, 8 new spark plugs, 8 new wires, new fuel filter and cleaned the MAF. Fuel pressure seemed a couple PSI low, so the regulator was changed out as well. No change in operation.
We have access to a scan tool with live data, so I checked some things out:
The O2 sensor reports a rich condition while wide open throughout the entire RPM range, so it's not a fuel delivery problem.
Fuel trims are normal, +/- 5-7% or so.
Calculated load was at 100%, pretty much from idle to 4500 RPM while wide open. This is very odd, as it usually takes a very high-strung N/A engine to hit 100% load at any RPM, let alone the entire RPM range.
Other things we've done:
We checked the reported ignition timing advance on the scan tool to the actual timing with a timing light, and it matched up perfectly, so no issues there.
However, I noticed that the timing light was flashing erratically at idle, and behaved slightly differently when clipped to the rear coil pack vs the front. Once the revs were up, the timing light flashed in a consistent manner.
Lexus GS 2006-11 :: GS300 Shaking On Acceleration With Light Throttle From A Complete Stop
My 2006 lexus gs 300 has this annoying issue where if i would accelerate with light throttle from a complete stop, the car would kick and sort of shake.. This happens the most and basically every time when i would slow down at a stop sign with using the brakes, then let go of the brakes and accelerate again, the car would feel like it has some sort of throttle delay and then you feel a heavy push/kick like the wheels are confused..

About 2 months ago,we noticed a slight noise when first starting the truck in the mornings.The noise was so faint,I could never tell where it was coming from.The noise went away when vehicle warmed. This morning,I drove it for the first time in a while,and its pretty loud now. Its definitely coming from the front of the motor somewhere.I am thinking it sounds like bearings starting to go bad.When looking at the fan spinning from the side of the truck,it does not spin true,there is a very slight wobble. With the motor off and grabbing the fan in the middle,with force,I can very slightly wiggle it back and forth. I should NOT be able to do that,correct?
By the way,truck has 142,000 miles on it and the water pump and timing chain were changed at 117,000 miles.
Lexus GX 2004-09 :: Cannot Open Passenger Door After Changing Actuator Motor
I changed the actuator motor on the DS passenger door. Now the door does not open. The electronic lock moves, locks and unlocks but the door does not open from inside or outside.
After a few tries the lock tab chatters but the door still does not open. What could be wrong? As far as i know i put it back together, like i took it out.
How to take the panel off from inside then i can atleast get to the two wires that go to the lock and see if i can open the door to take the actuator out once again.
Ford F-150 (2004-2008) :: Electronic Throttle Control Light On
I took it to a mechanic, he just told me to sprayed some carb cleaner on the throttle body and butterfly valve, and to wipe it with a rag. He did not hook a computer to it, to diagnose. and he said if the light comes on again to buy a new throttle body... I am thinking of getting throttle body sprayer taking off the throttle body replace the gasket, and hope this fixes my problem. I forgot to change my air filter btw.

View 2 RepliesLexus GX 2004-09 :: Motor Turns Over For Roughly 3-4 Seconds Before Starting In Freezing Temp
Noticed that motor turns over for roughly 3-4 seconds before starting when their GX has sat for awhile in well below freezing temperatures?
It's not slow turning over just takes a little bit longer to actually catch and start.
When the motor is warm or the outside temperature is closer to freezing or above I find that it turns over for no more than about 2 seconds before it starts.
I am thinking the longer turning over when cold is a good thing since the motor is starting to pump oil when it is turning over and allowing the internals to get lubricated before starting and revving.
Lexus GX 2004-09 :: Rear Door Lock Actuator Motor Stopped Working?
My left rear door actuator motor has stopped working and I have read about the repair of just the electric motor, BUT has anyone found the replacement of the little electric motor, Lexus wants a fortune because they want to sell you everything, cables, latches, it all comes in one bundle for 250 or so--Jeez. So hoping someone has the part number or place that we can get these little motors and just replace that!

I've had this happen twice: I'm stopped at a light (on relatively level ground--only slight incline). My gas engine kicks off. OK, fine. As it should. But then it comes on again, maybe a second or two or maybe three or four later, while I'm still stopped. First time, it did this a few times back and forth, all while stopped, waiting for the light.

I just got a check engine light today too! I wasn't sure if I should start a new thread but I found this one first so I'll see if I get any responses. Anyway, the diagnostic tool showed P2118: throttle actuator control.
I'm not sure myself if I should be worried especially since my wife and little one year old will be driving the SF long distance this week.
Ford F-150 (2004-2008) :: 2005 - Electronic Throttle Control / Wrench Light
2005 Ford F-150 FX4 5.4 V8
So my battery died the other day when I was working on the radio and I ended up having to jump start the vehicle. After the jump start the Wrench light came on the truck or the ETC light. (After doing research I have discovered you are not supposed to jump start a vehicle with ETC)
I have taken the car to the auto parts store and it does not seem the code readers they have can read codes for the ETC light.
I have also disconnected the battery cable to try and reset the light, but it still always comes on about 10 seconds after starting the car.
I have had no issues with the vehicle despite the light. No rough idle, no starting issues, or acceleration issues at any speed. What I can do to resolve this light or what part I fried when I jump started the car?
Prius (Gen 2) :: 2004 - Motor Doesn't Shut Off As Frequently When Stop At A Light
I have a 2004 Prius with about 50K miles. It is driven every day. I recently noticed that the motor doesn't shut off as frequently as it used to when I stop at a light. It then also shows the battery as almost empty (1 bar) on the touch screen. Gas mileage also seems to be a little lower than it used to be. Other than that the car drives fine. Could this be an indication of the battery starting to go?
