Ford F-150 - 1997-2003 :: Throttle Body Whirring Noise
May 28, 2013
The Throttle Body on my 2001, 4.6 L is making a strange whirring noise, when you puy your hand on the intake pipe, you can feel a slight vibration. The Truck idles and runs okay, with no codes. Giving it a little gas and the noise goes away. The last thing I did was clean the IAC with Gum Out Carb cleaner, the second or third time I've done this over many years, with no problems. I'm a little perplexed at the cause.

I have a throttle body noise that sounds like a warble,It is sporadic and I think it should not be their. But I have heard some other f-150s make the same noise. Is it normal or is something not right.

I need to clean my throttle body on my '97 F-150 and it has a label saying not to clean directly. Is it still safe to use TB cleaner and to go ahead and clean it? It needs done but how would I go about it.

I'm usually over in the EX forum but today was working on my brothers 1998 F150 - V8 4.6L. Had the EGR code P0401 and due to FTE I found the problem took the throttle body off and found it was definitely plugged. One of the bolts was really loose and came off way to easily. Didn't realize until cleaning why... Now I drilled 8 studs out of my aluminum EX heads but this one has me pondering how I'm going to clamp this thing down and center a bit..
1st pic - ports WOW - guessing this was the problem ...
2nd pic - bigger issue ...
3rd pic - the ports cleaned up ...

I busted the cable end by not removing it properly. My question is what is the proper method of remove the cable from the throttle body? Are the cable ends replaceable? If so who has them as a google search didn't find any? I've tried to find written information but haven't any luck. bl2009

I accidentally broke the control lever where the cruize control attaches. I've looked all over but I can't find the lever. Where I could buy just the lever? New throttle body is more than I want to spend.

High mileage 1999 4.6 4wd 5 spd: Needed to replace the rear ABS sensor and decided to clean the throttle body too while the battery was unplugged. Cleaned it around the butterfly and not much else. Truck idled at 750 BEFORE cleaning the TB. Now it fluctuates between 820 and 950 rpms. Also tends to stay at a higher rpm after pushing in the clutch and taking it out of gear.
Did a thorough check for vacuum leaks, nothing. After research, I cleaned the IAC and re installed (battery was disconnected then too). No improvement. Unplugged the IAC while running- ZERO change in idle. Installed new IAC, no change whatsoever. Unplugged NEW IAC, no change whatsoever. Is there an issue with the PCM needing time to fully re learn? Am I missing something.

So, instead of pushing the throttle cable back and then off, I tried to pop it off and broke the little tab. I've been trying to look for a replacement, but all I'm coming up with is an entire throttle body. Not too bad, but would still like to fix it for much cheaper. It's a 2002 F150 with a 5.4L.

Obviously its not a good thing, but this seems a little severe for a truck that hasnt had any issues prior. The truck is a 1998 F150 4.6 and was running just fine until POP!! A puff of grey smoke coming from the throttle body and followed by (obviously) a rough idle. So basically, I know that any metal fragments were directly sucked into the intake and based on the size of the chipped area (roughly 1.5cm). I am wondering what type of internal damage this would (or already has) caused.

My 97 Suburban died and will not start. Things I have done:
1 Changed fuel filter
2 Changed fuel pump twice
3 Checked fuel pressure 60psi
4 Changed plugs and wires
5 Changed rotor and cap
6 jumped switch to make sure pump runs
The Suburban will start only if I pour gas in the throttle body and will idle as long as I continue to pour gas in but will die when I quit.

97 Sierra K1500, 5.7 liter. High pitched whistling sound underhood in the vicinity of the throttle body. Starts after truck warms up and quiets down when accelerating. I've wiggled hoses, disconnected what I could without stalling engine, checked air lines into throttle body, checked air filter, etc. Sound does not change when I apply brakes so I don't think it's related to master cylinder. The only time it changes is when I accelerate, then only gets quiet until I come back to steady speed.
Truck has 85,000, runs great. No codes.

I have a 1997 f150 with the 4.6l triton that just started to make a squealing noise. I have replaced a couple of pulleys that were bad but that did not get rid of the problem. It only makes the noise when I give it some gas and it is coming from around the fan clutch area.

So i recently bought a used 2003 camry le 4cyl with 72k miles on it. So it's still in good condition. Previously I had a 92 camry 4cyl which is run with throttle cable. The new generation camry's now are drive by wire or driven electronically. So I decided to check out the whole car and looked into the throttle body, the out side of the butterfly plate, and notice some thick black substance. It seems like grease or oil. I don't know if its there to lubricate the motor to run the plate or just oil.

I just bought a 2005 fx4 and there is a whining or whirring sound coming from the rear of the truck when I hit around 70km/h. the second i let go of the accelerator it stops.
Today when I got home after a 15 minute highway drive, i got under the truck and felt the differential area. it was warm but not hot. and there was a wet spot on it. i wiped off a drop of oil. there was also a wet spot on the bottom, seemed to be just water? I'm not sure.

2001 F-150 4.2L automatic, 189k mikes. Gas pedal would do weird knocking/vibrating. It would do it at idle & under acceleration. Gas pedal would knock & sometimes slightly move or kick back at you. Felt like someone was lightly hitting it with a small hammer. Well there is not much to the gas pedal assembly; pedal, throttle cable & mounting bolts/plate. Looking under hood, a bracket from drivers side of motor was pushing back against firewall, which was pushing into gas pedal mounting bolts. I grabbed the bracket & it came off motor. Nothing else attached to bracket. Looks like it rusted off and was pinned between motor & firewall. Well, this fixed the gas pedal problems. But now i wonder what the bracket is & whats it suppose to hold??

Its a 2006 Toyota Camry 2.4l.. its been sitting for about 4 weeks now which has given me and her some personal time...I cant get it to run without me covering the intake hole. Last night my girlfriend and I were tinkering with it... before I sprayed carb cleaner and sealed the hole off with my hand she pressed the gas and I heard a grinding noise. So I told her to pump the gas with the ignition on and the gas peddles and the grinding noise was synchronized in timing. I turn the ignition off and press gas nothing... I'm guessing that's because its a fuel injected vehicle and everything is electronic (ECM) also I noticed when you cycle key from on to off it makes that noise also... won't start and I need my car.

I went to clean my wife's throttle body out with brake cleaner and I think I sprayed too much into the throttle body now the car won't start. It makes a small clicking/grinding noise when I try to start it. What have I done?

So starting with the specs: I have a Stage III+ Golf R with about 39k Miles on it. Stage III+ was added at 17k miles and has treated me pretty good. The car is driven about 3 days a week and has the oil change interval of 3k miles.
Things that I've checked or done recently:
- Cam Follower: Wasn't too bad but seemed like the outer coating was wearing off on it so I replaced it.
- Oil change: Changed the oil about 1 week ago but hadn't driven it since then until yesterday were we did about a 50 mile road trip. (No unusual things noticed)
When we came back home and parked in the garage, I noticed the sound when I turned the ignition off. It was pretty noticeable as you will see in the video. Could I possibly have a bad throttle body on my hands?

So I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.
It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.
The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.
The issue doesn't seem to be affecting engine performance.
The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).
