Chevrolet - Suburban :: Intermittent Surge Or Shudder Between 40 - 60 Mph During Acceleration
I have a 99 Suburban with very high miles. Going on 306K mostly highway miles. This is our baby and the best vehicle I've ever owned. This is a solid vehicle that I think we can get more miles out of.
The problem is that it will intermittently surge or shudder between 40-60mph during acceleration. It's hard to pinpoint because it doesn't happen all the time. It seems to be worse if the vehicle is low on gas or the engine is cold but I'm not certain about that. It's not hard enough to call a buck, jerk, or sputter though. Maybe I've over-analyzing but basically it will shift to the correct gear and then back down then back up etc., and back and forth for very brief seconds. Then levels out after 60mph and there are no other problems. If the gas is low or engine is cold is does this in lower gears as well but usually only around 4th gear. I hope this description makes sense.
Here's where I'm confused. The transmission was rebuilt 2 weeks ago specifically the torque converter and rear planetaries. The day we got it back we performed a tune-up so all new plugs/wires/cap/rotor. The fuel filter was replaced about 8 months ago and the fuel pump 2 years ago. All regular maintenance has been performed on time since we bought it 4 years ago. Yesterday the Service Engine Soon light came on and it only showed one code (OBD II), PO161, so we replaced the 02 Sensor (Bank 2, Sensor 2).
However the problem persists and there are no other codes providing any direction. I've tried to search the internet for drivers with the same issue but the fixes vary too much and seem uncertain.
Other known issues for diagnostics: four wheel drive hasn't worked for years (haven't needed it in our flatlands) and ac compressor went out last spring.
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Engine Light / Momentary Surge At Highway Speeds
I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?
Passat (B5) :: Surge Between Gear Shifts?
When accelerating hard I seem to have to consiously let up on the gas prior to clutch actuation in order to avoid having the engine "overshoot" a couple hundred rpm between shifts. Is this normal for the 1.8t?
View 1 RepliesDurango :: 2000 - Shudders On Shifting Gear / Surge A Little At Idle
I recently purchased a 2000 Durango with 151K on the clock. It looks like it was well taken care of, clean inside and out, and runs/drives nice. I just have 2 "concerns". There are times when the vehicles shifts from 1-2 and 2-3 it "shudders", only does it for a split second, and seems mainly when pulling out on some sort of upgrade, but not always. Otherwise it runs and shifts fine.
The second "concern" is that it seems to surge a little at idle. At a warm idle in park is when I noticed it. It goes from about 750 rpm to 950 rpm over and over. I haven't really noticed if it does it during regular driving.
Golf VI R :: When Idling RPMS Would Surge Ever So Slightly
I've been dealing with this for some time now because it hasn't seemed to affect my performance when I am getting on it, but when I am at idle the rpms will surge ever so slightly and i can watch the needle on my boost gauge bouncing up and down. i have a WINtake on the car and it started ever since i installed that. I am wondering what this could be. I've already taken the whole intake out and reinstalled thinking i had a leak somewhere. even tried swapping my maf with a known good one off the lot on a brand new R.
I read somewhere that someone had their maf in backwards. could this be the issue? I don't have any power loss that I am aware of. in fact, if its down on power now, i would have a hard time believing that it could be much faster with what i have done to it. this idle surge will get worse when i have my ac on also. someone make me realize that I am missing something stupid and simple here so i can have a normal idle again. I am half tempted to put my stock intake back on to see but i no longer have the turbo inlet plastic pipe to test it with.
Golf VI R :: RPM Will Occasionally Surge Up When Coming To A Stop
So I have the warranty on my car still and I've brought my R into the dealership to have it checked out. They want to do more "diagnostic" work on it since they're not sure what's wrong with it.
The Issue: When coming to a stop, the RPMS will occasionally surge up to 1500ish RPMS, before slowly dropping down to the idle 800ish.
CEL has come on twice in the past month after a day or so of this happening (first time, CEL went away on it's own after 3-4 days, 2nd time, I had the code cleared at the dealership).
Code: P0507 - Idle Air Control RPM Higher Than Expected
I'm thinking it's the PCV valve failing, or in the process of it. The dealership says they think it's an air leak somewhere in the intake system...which would make sense to me if it was a static, constant problem, but it's not. Therefore, through deductive reasoning, I believe it to be a moving part or a valve or some sort that is failing to operate properly.
The car is 100% stock. I have to take it back into the dealership in a couple of days, and I would like to suggest they check the PCV valve if that is the general consensus on here rather than waste more time.
Golf IV / Jetta IV :: Surge / Stutter - No Boost Leaks
Replaced my coil packs/sparks, and just got around to changing my N75 valve today. The rough idle issue is gone but now when I go WOT it boosts but goes from 15psi-12-13-12-14-12...etc. I've checked and there are no boost leaks. I do have a CEL saying I need a new bank 1 sensor 1 Oxygen sensor. If it is that, why did this problem arise as soon as I changed the N75 valve and wasn't present earlier?
View 1 RepliesGolf/GTI VI :: During Cold Start Cycle Getting Misfires And Air Surge
Ok, to start off. I have a 2010 2.0T CCTA with 23k miles. I recently purchased a HPA Intake Manifold and installed it myself. I was told by HPA that they offer a tune specifically for their manifold. I however, purchase the Maestro suite by Eurodyne with the intention on getting it all tuned myself. I was able to code out the CEL for the flappers no problem. Now my only issue is the cold starts. During the cold start cycle I get misfires and air surge. I ran the fault reader and got the P0300-P0304 (Misfire faults). Obvious thing to check were plugs and packs. So I changed them. No change.
I read in a bunch of threads that these faults as well as air surge are a sign of the PCV Valve. I have a catch can kit on order so I will see if that wotrks. My guess is no. Another thing I think it could be is the N75 valve however, this issue only occurs during the cold start cycle. After the cold start cycle is done I have no issues what so ever. So I ruled out the N75 valve. If it was bad, then it would be bad regardless of how cold/warm the engine was. I have attached a video of the Cold Start.
Golf IV / Jetta IV :: 2000 - Sudden Boost Surge To Almost 20 Psi
I have a 2000 Jetta 1.8t. I am having a sudden boost surge problem. It seems no matter what gear I am in if I get on the gas when getting on the highway or whatever to just get up to speed in a reasonable amount of time, the boost just increases like crazy. I do have Gonzo Tune and know I should have a faster response but I have been in higher built mk4's and they don't do this.
I have done the following to try and fix problem and some cause it was just time to replace:
New MAF
New N75
Fixed Leaks
New Plugs
New coil packs
New Fuel Filter
I do have a boost gauge and when cruising my vac is steady. The sudden surge of boost goes to almost 20 psi. I have thought of replacing my wastegate actuator since I have heard that can be a problem?
Golf/GTI VI :: 2011 TDI Surge - Burning Smell From Engine Compartment
I bought a 2011 VW golf TDI back in August. I current have 12,000 miles. I got my 10k oil change at the beginning of Dec. I ask them to look at the injector recall as well. Everything seem good so far. Until today..... I was out with my girl today getting the rest of our Xmas shopping done. As we were waiting for the light to change the car started surging. Not like a sensor surging but a little surging. I thought it was doing just its thing and it would stop. We pulled in to where we shop and did our thing and headed back out.
Again it started to surge. 5 mins later we pulled into our driveway and started to smell a bad odor coming from the engine compartment. Really bad that she could smell it from inside her side of the car. I can't describe the smell. Maybe electrical not sure. We let it cool down and now I'm about to check out. I have to go to work tomorrow and I'm not if I should drive it or not. I drive 158 miles a day for work.
Golf/GTI VI :: 2011 TDI DSG Occasionally Will Surge When Cold At Parking Lot Speeds
my (new to me ) 2011 TDI DSG occasionally will surge when cold at parking lot speeds. You all know what im talking about. Ive found a handful of updates and TSBs that deal with it, but they said they cant apply unless they can replicate it. I left it over night so they can drive it cold and of course, they cant reproduce. I am gonna go back in 4-5hrs after it cools fully again and ill drive him this time. Annoying nonetheless.
Couple other questions: The car just got a 30k 4 mos ago. From prior records, the previous owner had the fuel filter changed at 20k in June 2012, then the 30k svc was done in Jan 2013. Should I be proactive and change the fuel filter now before the 40k or just wait it out?
Should I press for any other maintenance, etc to be done (car is at 35,900 miles today)...?
Golf/GTI VII :: Compression Surge / Turbo Flutter At Low RPM On High Gears
So I'm wondering in a nutshell; in layman's terms... what is compression surge and turbo flutter if you had to summarize it in a few sentences. I was told that its worse with a tune, but even our stock cars have it? I'm not very tech savvy so on the articles I found and read it's said to be bad and basically happening at low RPM on high gears?

Golf VI R :: Light Drivetrain Surge When Making Low Speed / Tight Cornering Radius Turns
When I drive in a parking lot or parking garage and start off into a slow, tight corner, I feel a "surge". If I had a locked diff I would understand. I have a Haldex composition controller. I am not bothered about it...just wondering what it could be. Maybe the clutch slipping?? No evidence of that at full throttle acceleration runs in the higher gears.

I have an 07 Hyundai Accent. Occasionally when I start it, it will bang into gear and will not shift into high gear. It is an automatic transmission. If I turn it off and restart a couple of times the problem will disappear. I occasionally get the check engine light with this problem but it goes out the same day. It has also occasionally been going down the highway and will shift out of OD and increase rpms. I can pull over and restart and the problem goes away.

Took my 2011 F250 in to the dealer where I purchased it concerning intermittent misses on gear changes. The dealer had no history or knowledge of problems with shift flares. I was told they would check it out. Bottom line, their checking it out yielded no results, no action, and no "engagement", pun intended, to resolve a serious concern. How did others resolve the issue when it came up?

View 3 RepliesGolf IV / Jetta IV :: Very Hard To Get A Smooth Shift From Gear To Gear
Background facts:
Tranny swapped from my 4 speed auto to a 1.8t o2j 5spd
13lb. Light flywheel
Powerflex dogbone mounts
Peloquin LSD
The problem: Very hard to get a smooth shift from gear to gear. Trust me, I know how to drive, but I can always feel the car shifting into a different gear if you know what I'm saying. On my friend's bone stock Jetta, I just let the clutch out without gas in between shifts and you don't feel a thing.
On my car, you feel EVERYTHING. People have told me the light flywheel will make the ride more uncomfortable in many ways, especially since the RPMs drop much quicker in between shifts than stock.
