Golf IV R32 :: Whistle Sound Under Acceleration For Some Time - Bad Throttle Body Gasket?
Dec 2, 2013
So i have been hearing a whistle under acceleration for some time. Normally comes at 1/2 to full throttle. I also have had check engine light for a bad o2 sensor for about the same amount of time(2months). Fast forward to last week. finally replaced sensor. Check engine is gone. Open her up a little on and on ramp, Whistle is still there and the CEL comes back. Have it scanned, and it come back load calculation cross check 17551. I need an sticker so i rest the ecu (no light) and drove it like a grandma 50miles to get the sticker. No CEL. Get sticker. Just to make sure i wasn't crazy i gave her some gas on the way out of the inspection lot, and there is the CEL.
In conclusion, Between the whistle, CEL, and the fact that i drove it 50 miles with out the CEL coming back under very light throttle, and i just replaced the MAF with a new Bosch 2 months ago, i am pretty sure it is some kind of vac leak.
I have a new TB gasket in the mail, but my question is, Is there other places where such a vac leak is common in these cars? Other info on car.
UM tune
evoms intake
HPA downpipes (whistle started after these where installed)
Flapper
no res
74k on the clock

Took off throttle body on 3800 series1 S/C and coolant is leaking from both bottom ports from mounting area on motor. Is this normal ? Intake area into S/C was dry but very much build up. The 2 ports just end at bottom back of throttle body and are sealed by the gasket. Coolant comes out steadily from those 2 holes. Is this an intake problem, gaskets ?

Few weeks ago.....Prius was showing the P0505 code .... Mechanic, ran diagnostics and determined it was dirty TB. Cleaned TB.....cleared the code (inspected PCV...hoses).
When I initially picked it up it was revving very high....so he hooked it back up to the scanner and did some type of "reset" for the idle (this cleared most some computer settings...back-up beep, radio stations, etc...). Everything ran fine for past 3 weeks...
Just last night..... started running rough again. What I noticed this morning ... Started it up and it ran very rough til the auto shutdown after warmup (no warning lights). Then....when I started driving slowly out of the lot...it ran "rough upon acceleration"...... Then fine at cruising speed. Same behavior at every light....rough acceleration.... fine once up to speed. Just started it up again and same behavior.....(does not die...just very rough).

It's a 96 850 Naturally Aspirated. There is a whistle sound (usually about one second in duration) when I let off the throttle.
Based on what I've been able to find out so far it is most likely at Vacuum line or a gasket somewhere in the intake line. The more common source of this is the Throttle body gasket but that doesn't seem to be the case.
I think the sound is originating on the left portion of the engine, somewhere between the oil cap and the timing cover.
Any good ways to test the vacuum lines or gaskets?

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.

So while driving yesterday I had a EPC and Check eng light come on and go away shortly after... maybe 1hr of drive time. Any way I took into dealer today to have them scan and they stated it was an issue with my throttle body.
Now as soon as he told me that he also said he can not do any work under warranty on my engine due to Stage 2 software and intake/down&mid pipe...... no big deal as I figured he would say something like that anyway. Should I take it apart and try to get it cleaned..... or what?
Its a 2010, with roughly 21k miles.... Had APR stage 2 for a few months now and this is the first thing that has come up.

2002 camry. The car will not accelerate. The throttle body makes a clicking sound when pedal is depressed.
So.. I took it apart and cleaned the contacts in it. In the mean time located a spare throttle body from a 2003 from a local yard. The old throttle body has a part number 22030-28030 and the replacement has a part number 22030 0H010. The replacement throttle body wouldn't even move when the pedal was depressed.
I put the old one back on.. and now it doesn't click anymore but the car in Park only revs to 2000 rpm's. Its not sticking or having any mechanical issue.
I checked the parts site for Toyota and the replacement is the new number. Superseded. Does the throttle body after replacement need to be reprogrammed? Or whats the deal. I wish I was more Toyota literate when it comes to this.

Started my car this morning to warm it up, idled for ~ 20min. weather conditions. I returned to my car, and it was misfiring and threw the p1545 throttle body code. There was a mk5 tsb for a similar problem involving wiring. 49k miles, stock tune, w CTS catted dp.

I decided to take out the throttle body and clean it with throttle body cleaner that I got from autozone, after I put everything back, I started my car and the motor was shaking and smoking a lot out the muffler and just would not be drivable at all. the RPM was just going up and down and hesitating bad. later I took off the spark plugs and they were very much burnt black at the tips and that is probably not normal right? but I replaced them with NGK BKR7E spark plugs and it still gave me the problem.

I have a customer that has a 2.0 mk4 with 260000 miles on it..about 20k miles ago we had 6 codes saying throttle body was not working and car was surging, so we ordered a vdo tb, installed it reset tb and it ran fine for 7 months and 20k miles. Again car is surging, so i tried a tb reset. tb was under guarantee so we took advantage and replaced it/reset it and it threw a code within 5 min of driving and hesitating/surging. He is original owner? possible ecu getting sleepy?

So the other day I went to the mechanic for him to see what code(s) were causing my CEL. He simply told me that there was an issue with the throttle body and it didn't know what position to be in; he cleared the codes, clean the throttle body and said if the light came on again I needed a new tb. The CEL came back on, but his diagnosis doesn't make sense to me.
From what I've researched if the throttle body had this issue the car would run like crap; however, it runs fine. Smooth idle, good throttle response, accelerates smoothly through the rev range, and I'm still getting decent fuel economy. Given that, it doesn't seem like it's the TPS either, and the tb was just cleaned so I'm confused. Could it actually be the throttle body, or is there some sensor that has just gone bad? The car is a 2000 Golf with an AEG engine & 5-speed box.
And here are a couple pic for clicks of a stock-ish car.....

My wife and I just bought a pre-owned 08 Jeep Grand Cherokee with about 60,000 miles that just started to make a whistle sound on initial acceleration and deceleration when the engine is warm and the transmission is in gear and moving. The sound does not happen with a cold engine, when the transmission is in park, or neutral. A local mechanic checked it for vacuum leaks and didn't find any. He thought it may be a dirty throttle body, so I cleaned that out really well, but the whistle didn't go away (it did make the jeep run a lot smoother!). It's difficult to pinpoint the noise since it only happens when the vehicle is actually moving.

I have been having the dredded EPC light coming on and according to the vag scan its the throotle body. What I need to know is if one off a 2003 2.0 jetta will work on my 2004 2.0 jetta. The number on the side of mine 06A 133 062s is not the same number on the 03. I was told that they must match to work properly.

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?

I have a 02 2.0 Jetta with 179k
Have that pesky "whistle under acceleration" when past 1/4 throttle issue. I have been going over the entire engine, checking and cleaning.
-----On the intake tube where the 1 inch case vent and half inch tube meet there is a Flapper/Flow check with a electrical connector directly on top.
Question being, is this a flow sensor? The flapper is distorted and does not function properly.. is this an issue?

I searched but couldn't immediately find anything about this particular line. I've been struggling with a rough idle for the past couple weeks, throwing codes that I'm running to lean all the time. I cleaned the throttle body and MAF, and was in the process of replacing the MAF and noticed a small hose fitting behind the MAF but before the throttle body was pretty much split in half. I don't know what it's for and I'm replacing it regardless, but could this be the source of my problem?

I have got a 5 door 2002 Golf 1.6l petrol, manual transmission with 190k kilometers on the clock. It has been playing up recently and the authorized VW garage is clueless, but still happy to charge for a miserable job...
The "symptoms" are always the same: I can start the car no problem. Plenty of water coming out of the exhaust and EPC light comes on, no power transmission (or very little). In this state, the engine runs irregular. Before all this happens, you can tell there will be a problem (this is not super obvious), as the car does not run smoothly in neutral, especially when it is at a a hill You might get away with another 50k but that's it.
Breakdown 1: Called out road side assistance and got it towed. Volkswagen dealer retrieved the error code P1564 and they replaced the throttle and some of the contacts of the throttle. (Costs 800 GBP)
Breakdown 2: However, 300 km later, same problem as before road side assistance retrieved error code P0638. The memory was reset and it did run perfectly fine for a short while (2000 km).
Breakdown 3: As before, error message P1564 was read. This time they thought there was a problem with the coil in cylinder 2 and replaced it (250 GBP) - also the one in cylinder 1 as "old". Picked up the car and it was not running smoothly in neutral and it eventually broke down after only 90 km.
What to get changed next? What is the real root of the problem here?
