Golf IV / Jetta IV :: 1.8t - RPM Going Up And Down / Hesitation After Cleaning Throttle Body

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.

Golf IV / Jetta IV :: Rough Idle / Small Hose Behind MAF In Front Throttle Body Split In Half

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?

Golf IV / Jetta IV :: 2002 - Replace Throttle Body And Coil In Cylinder 2 But Again Error Message P0638?

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?

Toyota - Corolla :: 2000 - Cleaning Of Valve / Throttle Body?

Car is 2000 Corolla with 60k miles that sometimes has a low idle (sometimes) when driven for the first 15 minutes early morning. Especially when accessories turn on, the RPM drop suddenly to 600 and recovers to 623 then back to 650rpm. After 15 minutes, everything works fine (normal 650 rpm)....my guess is the IAC Valve/throttle body needs cleaning.

What exactly do I need to tell me mechanic? That both the IAC Valve and throttle body needs to be clean? Also, after "cleaning it using a spray"....should he wait till the "spray dissipates"? What happens if it goes inside the engine?

Golf/GTI VI :: 2010 - EPC / CEL Came On - Throttle Body?

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.

Golf IV R32 :: Whistle Sound Under Acceleration For Some Time - Bad Throttle Body Gasket?

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

Golf VI R :: Strange Clicking Noise Coming From Throttle Body During Ignition Shut Off

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 2005 Jetta 1.8t and the thing will not start! The battery is fine, and has been recharged 100%. The fuel pump is pumping. It cranks all day, but just won't start. The only error code i'm getting is a P0411 which I understand is a leak in the vacuum system somewhere.

Golf IV / Jetta IV :: Cold Air Intake Causing Water Logged?

I have a 337 with Injen cai. Well, I have since removed the cai due to the fact that rainwater/water during a car wash will run off the hood and onto the top of the inside of the drivers side fender (under hood) and eventually run down onto the filter itself, thus causing it to become water logged. This of course is not good. My question.. I've tried so many things to no avail.

Golf IV / Jetta IV :: Vacuum Pump Rivets Causing Noise At Startup

I have a raspy exhaust leak sounding noise when I start my 2003 GTi 1.8t that cuts off just a few minutes after I start the car and a fellow owner told me he thought it was a vacuum pump that has rivets that fail and allow the case to separate and cause this noise. Where this pump is located? This former coworker of mine said he replaced the rivets with long slender screws and nuts after removing the rivets but I lost contact with him and don't know where this pump is located.

Golf IV / Jetta IV :: Overheating - Coolant Spraying Everywhere Causing White Smoke Under The Hood

I have a 2002 VW MK4 1.8t. It has 172,000 miles on it. Since i bought the car i have had to add coolant from time to time due to leaks from various plastic coolant parts so I replaced the crappy plastic connectors and flanges as they failed but it has never overheated till a couple days ago. It rose up to about 210'F but I didn't let it get to 260'F (aka the red zone).

While the temperature was up, the coolant was spraying everywhere causing white smoke under the hood. I stopped and looked under the hood and came up with the conclusion it was the coolant flange that holds the temp sensor since it was leaking coolant from the flange like a faucet hince the reason it caused it to overheat due to lost of pressure and no coolant in the system. So I replaced the part and gaskets then checked for other obvious leaks.

No leaks are shown nowhere else in the vehicle. So I added coolant to the car and let the cooling system do its magic as i left the heater on high. Let car idle with cap off and heater on for about 45 minutes. No signs of overheating. So I take the car for a spin and that's when the car starts heating up. I look under the hood and feel hoses and notice all are pressurized but top hose that leads to coolant flange is hot and the bottom hose connected to thermostat is cold.

I checked the return hose that leads up to the coolant reservoir to see if it's cycling and it appears it was. At low rpms the return hose had a steady flow and at high rpms it was flowing much rapidly. Which made me think it wasn't the water pump also this car with that many miles wouldn't have lasted with the plastic impellar this long if it wasn't already swapped out by previous owners. My question is what would cause it to still overheat? I forgot to note the fans did not turn on when the temperature was rising unless i turned the a/c on. But i still did a drive test with a/c on and it still overheated. I also did multiple burp cycles. I have invested alot of money in custom work and suck to leave it parked on the drive way.
