Golf IV / Jetta IV :: Turbo Flutter Over 20 Pounds Of Boost
I have an 03 GTI 1.8t with the stock K03s turbo and i used to boost to 25 pounds. Had to put a new motor in and now i when i boost above 20 pounds i get turbo flutter and loose boost. I can boost anywhere up to 20 pounds and the turbo doesn't flutter at all.
I had a spring on my waste gate which i have taken off and it changed nothing. I tried a different diverter valve and it didn't change anything. I unplugged the MAF to see if the N75 or the there was a boost leak and extra air wasn't being monitored but still changed nothing. It has nothing to do with my RPM range just when i boost over 20 pounds. I am planning on doing a leak down test to make sure there isnt a boost leak....
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Turbo Flutter After 50% Or More Acceleration
So I bought my first diesel last night and I'm in LOVE!!! It's an 06 F-250 with 6.0 (obviously). It's bulletproofed, rebuilt FICM, EGR deleted, and 4 inch exhaust IIRC. Previous owner had an issue with the turbo and replaced it. New turbo was DOA so he rebuilt it (sort of) and added a precision turbo (again IIRC) back housing (I think) to it. It has an SCT tuner as well and I have it set on the custom economy tune. Is this normal? Is there something I need to be doing about this?
View 6 RepliesFord 6.0L Power Stroke Diesel :: 2006 - Failed Glow Plugs And Engine Flutter In Upper Gears
I've recently gone through and replaced all 8 of my '06 6.0's glow plugs as the check engine light has successively come on (I first did #3 about a year ago, then #5 seven months ago, #1 and #7 two months ago, and #2, #4, #6, #8 about two weeks, did all 4 on the drive side even the code was only for #6). A light came up for #1 again today, so I'm wondering would this be symptoms of failed glow plug control module? Also, can a failed module cause the glow plugs to fail prematurely? Haven't had a chance to ohm the plug yet.
The truck has also has been hard to start when cold and had a pretty bad engine flutter the past 8 months when cold at medium range rpms in the upper gears (1500-2000 rpms in 3rd, 4th, and 5th gear and accelerating like a grandma). I don't know if it could be glow plug related, or a bigger issue (I did the EGR/Oil cooler myself about a year ago as well and things ran good until the winter hit). If I plugged the truck in over night over the winter, the flutter was not nearly as bad, but now it's summer and it's still not liking the cold take offs.
Golf IV R32 :: Turbo - Misfire Under Boost / 1k RPM Idle (high)
Car started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
Ford Excursion :: Turbo Surge - Cannot Maintain 70 Mph With Small Load Up A Mild Hill
I have a 2002 EX 7.3 and have never towed anything with it since purchased a year ago. This weekend I towed a side by side on a single axle trailer about 400 miles and could not maintain 70 mph with the small load up a mild hill. Also I could here the turbo surging while climbing hills. I have a AFE cold air intake and that is it. Truck had a aftermarket muffler on it when I bought it. New to the diesels but I thought it should tow that Trailer a little easier. I have no boost gauge or anything. Truck runs great other then this issue. Does not burn oil, get hot or anything out of the ordinary.
View 14 RepliesGolf/GTI VI :: Mushy Clutch Feel - Slipping In High Gears?
I've just about had it with this car:
- Car always had a "mushy" clutch feel. Not proper pushback against your foot feel.
- brought in several times under warranty, all was fine (documented by several dealers) from Jun- November 2015.
- Clutch then goes out at 52k, slipping in high gears. Dealer noted the pressure plate was blackened/burnt. June 2016
- I replace clutch at dealer, $1700 later. Pressure plate, slave cylinder, clutch disc, resurfaced flywheel. Pedal feel is awesome for about a month. Pedal "mush" comes back 1000 miles later. July 2016
- Take it in under the 12k warranty again, and they replace clutch master cylinder. It's about 60% better, but pedal will lose pressure occasionally and at higher altitudes (over 4000 feet) July 2016
What else haven't I replaced? And would a failed clutch master cylinder cause premature clutch wear if not replaced for months?
Ford F-150 - 1997-2003 :: Idles Fine With Occasional Surge / Sputters In All Gears Like A Misfire
I have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.
Golf IV / Jetta IV :: Stalling In High Gears But It First Start Doing This When Hit Boost (3000 RPMs)
I have a golf mk4 1.8T AGU, about one week after i had my k04-023 turbo on and all the Stuff that comes along it started "stall" (don't know if its the right word??) in the High gears, most 5th gear but it first start doing it when i hit boost (3000rpm)
I runs on Stock n75 valve.. I though i could be a boost problem, maybe the Stock system cant handle it? I did install a boost gauge to see if it was the was the problem, and it dont Seem like it. In first it runs from 1.4 bar and drops to 1.2. Same in second and third. But in 4 and 5th it goes to 1.7 bar and drops to 1.4.. I did wonder it maybe the n75 valve cant handle 1.7 bar??
Golf/GTI VI :: Flutter After Installing New DV
I installed the pierburg revised DV yesterday because my old DV was shot, squealing and leaking boost. After installing it I noticed that when i'm under around 15 psi and i let it build up that I get this flutter I didnt have before. I assume its the wastegate but I haven't heard it prior to installing the new DV so my fear is that its the valve no circulating and its putting the unused psi back through the turbo (not good).

Going through the drive thru tonight and I heard a weird noise coming from the engine area. Get home and pull into the garage and here a flutter sound when my clutch pedal was pressed down, let go of the pedal no noise. While driving the car around clutch pressure seems fine and no slippage of any kind.
View 2 RepliesChevrolet - Blazer :: RPMs Surge High At Startup, Then Dies
I have a 1998 Chevy Blazer (2WD) with 115k miles. When I turn the key and start the car, the RPMs rev up really high for about 4 seconds and then drop down real low until the car dies. All in all this is about an 8-second process, and it sounds like I'm flooring the accelerator when, in fact, I'm not even touching it. The Blazer just started doing this, but previously for about the last few months about once a month, when I would start the car I would get a loud backfire sound which sounded like it came from under the hood (driver's side), and this was followed by the smell of exhaust coming into the cab through the AC vents. How to go about diagnosing this since I'm unable to drive it to get the codes read
View 11 RepliesSanta FE SM (2001-06) :: 2004 - RPMs Running High / Car Seems To Surge
2004 Santa fe. Having issues with RPM running high. When car is started, RPM sits at 1500 for a few mins, then drops to 500. Seems to be having issues either getting into gear or staying. At any mph, car seems to surge and not feel like it's getting either gas or power. While on cruise at 55+ mph, car will also surge with RPM dropping 500, then kicking back in. This goes on every few seconds up to random times.
Had it looked at this past weekend at a dealer, and of course it didn't do it one time, after doing it for a half hour prior on the interstate. Tech found no error codes when he checked it as well. Car was fine for an additional 300 miles, then it started again out of the blue. Pulled out at a red light and I though I was going to stall.
Just got laid off so I'm trying to eliminate before putting a lot of money into it if I don't have to. 132,000 miles.
Ford - Ranger :: 2003 - Rev Surge From Low Idle To High Every Few Seconds?
The revs surge from low idle to high (about 1000 rpm) every few seconds, but only when the truck is in gear,and the AC is on. What it could be. Also is it something I could fix myself? I have been driving with out the AC for a while but going into summer I need it on.
View 2 RepliesGolf V R32 :: Loud Flutter / Rattle When Change Gear Above 2500 RPM
Whenever i start my car and begin to drive, i get a loud flutter/Rattle when i change gear above 2500 rpm. It occurs when i give it about 50% or more throttle. is this normal? or does it have anything to do with cold start? I have a tampa mod resonator on the car.
I have a video to show sort of what it sounds like, but this is with giving it about 30% throttle, not 50%. it gets much louder, and sounds a lot worse when i give it more gas. Listen at 1:07.
3000GT/Stealth :: Extremely High Idle - Surge Between 1300 And 1800 RPMs
So I had this issue with my idling at 1300 rpms but every now and then it would idle at 400 and barley run then one day it didnt want to idle at all so I checked the iac and it was bad so I changed my oil, fuel filter, iac, cleaned my throttle body, fixed a vacuum hose, and cleaned my air filter.
When I started it it idle at 2200 I drove it a little and it dropped down to 1300 the next day I started it and it idled at 800 and staid there for four days now it idles at 2000 then will drop down and surge between 1300 and 1800.
I read that the oil you apply to the filter can contaminate the Maf and you should clean it but a lot of people said the one on a vr4 can't be cleaned while others say it fine. Is there a way to check the maf?
Golf IV / Jetta IV :: Blow Off Valve Started Making Flutter Noise When Dumping
I recently put a cold air intake on my car and I could hear the dump when I let off of the gas. But I also put in a boost gauge but I think I had a leak in the hose going to the gauge. After I drove it for awhile the blow off valve started making a flutter noise when dumping. I fixed the leak in the hose but the flutter is still there. How do I fix the flutter? A new blow off valve? Mk4 Jetta 1.8.....
View 6 RepliesGolf VI R :: Clutch Noise When Downshifting On Compression
I have a strange noise issue on the clutch since day 1. When on regular driving, if I'm decelerating on compression and downshifting from 4 to 3, and 3 to 2nd (like slowing down to stop at a red light), when a release the clutch slowly, at the friction point, I am hearing a scratch noise, like 2 metal parts are touching each other.
When totally depressed, no problem, when totally pressed no problem too. Only at the friction point. It's more noticeable when downshifting from 4 to 2.
Golf IV / Jetta IV :: VR6 Misfire On Cylinder 4 - Low Compression Level Of 90
I am a new vr6 owner. I just purchased mine not to long ago. It seems to have developed a pretty mean misfire on Cylinder #4. It is also showing a low compression level of 90 on cylinder #4. all my other cylinders show somewhere between 105-110. I replaced my wires and my coilpack. It did not improve anything, infact, my car seems to run worse now. I am baffled as to what can be causing my misfire.
