Passat (B5) :: Idle Sputter / RPMs Will Drop Then Will Eventually Stabilize
Mar 3, 2007
As listed above I own a 98 Volkswagen Passat. It seems to run just fine for the most part, but if I push on the gas and let off I notice a slight sputter. The RPM's will drop to about 800RPM up to 1000RPM and back down again and it will eventually stabilize and idle fine. My only guess that I have so far that I read on a post somewhere is that the EGR Valve tends to get gunked up and stick. I will try to clean that off.

I have a 92 grand prix. Out of nowhere when I hit my brakes the car would sputter & eventually die. So I had my break booster replaced & now not only does it still sputter it's has a lack of power when accelerating & I can smell a little oil burning. It hasn't stalled but it sure isn't running smooth. Is the booster bad? Do I just need a new air filter. I've haven't seen any leaks & the brakes work fine so I don't think it's the master cylinder.

when the temperature is above roughly 60 degrees, I can drive the car for a short while, even a few miles, and it will start to sputter and eventually stall. At that point the car won't start, it turns over fine, but sounds like it's not getting any gas. If I wait 15-20 minutes it starts fine and will repeat the same process. Is there some temperature sensor or something that prevents the engine from starting after it gets hot, or is it something else. The temperature gauge doesn't indicate the engine is hotter than normal. I've taken it to my car shop twice and they haven't found anything. 1991 mercedes e300...

I've made posts about a rough idle before now I noticed something new about it. I noticed when I approach a red light the vibrations don't start immediately. They start as soon as the RPMS would drop a little. They stay above 500 but it seems like it's below 750. As if the engine is slightly starved from power? Now i'm wondering if it could be related to another problem I have.
Whenever I start the car, the battery light flickers until the car is started all the way. This is on a 2007 Camry 4 cylinder. So far everything iv'e done is: New NGK Spark Plugs, NEW OEM mounts (all 4) Seafoamed the engine, Seafoamed the throttle body, cleaned the MAF sensor, New air filter, and cleaned the air filter box, replaced the PCV Vlave, new belt, new alternator (duralast), and a new battery (from autozone).

1997 Subaru SVX (Alcyone) LSi, 3.3L H6 engine.
My SVX was driven from Denver to Las Vegas, NV and it developed an odd habit where the RPMs would start to oscillate while on cruise control. I had to disengage the cruise control to get the oscillations to stop. Three days later I was driving the SVX to work and the RPMs started oscillating at idle and the car started running rough and it died.
These things have all been replaced with OEM grade parts: Spark plugs, electric fuel pump & strainer & fuel filter, Mass Air Flow sensor, new air filter and fuses.
The car starts up fine but after a few seconds the RPMs begin to oscillate. Then the car tries to recover, the idle becomes rough, and the the RPMs drop very low and the engine shuts off.

Twice now this has happened to me and I'm concerned it will become worse if I don't fix it. Driving down the road my engine has disengaged. By this I mean the vehicle both times has been at 55 MPH, my foot on the throttle rpms riding around 1300 revolutions, and the engine disengages rpms drop below idle and my "wait to start" light comes on. This both times lasts approximately 2 seconds and throttle reengages while still traveling 55 MPH, "wait to start" light goes off and its like it never happened. What's going on with my truck?

I have done everything I can think of to this car. New; plugs, wires, distributor, battery, fuel pump, fuel filter, relay, and electrical lines to fuel pump. The timing belt is fine. The car has a rough idle and when I am stopped the RPM's drop below normal. Now it won't start. What can I try now?

I have a 1997 Audi A4 that has been acting a little bit strange lately. When it is started up and left to idle all of a sudden the RPMs drop from around 600-800 to 100-200 sometimes rebounding back up and sometimes the car just dies. This also is happening while I am driving and stopped at a stop light for a short time. It will idle fine then suddenly drop RPMs and if I don't give it any gas then the car usually dies. I have just had some work done on it to try and fix this problem thinking it was the air flow sensor (or something like that) but apparently that is not the case.

Cold start. engine starts but wont idle, just dies. rpms drop. Restart same. Must neutral drop to get going keep rpms up until engines shifts then things are fine until next cold start. Cleaned throttle, changed air filter, dry gas, injector cleaner, no warning signal, scans clean. 180k miles.

Hot or cold car always starts,Idles perfect , then RPM drops, Idles rough and stalls. Econometer moves to Red area.car will easily restart and drives well,it also idles well. Once engine is shut down, even for a short while, It does the same thing again. Car is used for short trips. Ambient Temperature 80 degrees. Once running car is perfect at all speeds and idles smoothly. Hero 1987 MB 560 sel ....

My '03 7.3 is "surging" on idle. When warmed up, and idling, the RPMs will drop by 300 or 400 for a few seconds and then will correct and shoot back up. It cycles like this (every 5 seconds-ish) continually . I just put in a new IDM and checked the UVCH - is there a separate idle control mechanism that I need to have a look at? (2003, 7.3, 214K, stock).

I have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.

I have a 98 1.8t TIP and this problem just started happening when I slow down to stop the rpm's drop and it almost dies but it catches it self and the needle bounces a few times and it is fine after that.
Also when I start the car the rpms bounce like three or four times but it again, catches itself and its fine after that... until i want to come to a stop again.. I live in the city and its a lot of stop and go.
Also when i slow down it feels like my car slams into first gear. it shift perfectly every other time up and down, only when it goes into first it hits hard and scares me cause I don't want anything to go wrong.

Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

One of my Aerostar pet peeves is to do with the sliding door alignment, or should I say slight misalignment.
Some of the alignment problems can be attributed to worn out nylon roller bearings. Make sure the roller guide ways are clean of any foreign debris. When you car wash your Aero, make sure to also clean the interior roller guide way (open the sliding door and thoroughly clean around the area where the bottom sliding door wheel travels).
After 20 years of usage, the sliding door will eventually drop down and back a few millimeters. Some of the symptoms associated with this will be a sporadic loss of electrical contact with those that are outfitted with electrical door locks. Also, the sliding door may also require some manual assistance at back edge to open the door. It can become somewhat frustrating, and perhaps a little embarrassing when parked beside a newer vehicle outfitted with automatic door opening/closing mechanisms.
I am not sure if the elevation of the sliding door can be adjusted at the rear or in the middle, but I do know that the horizontal position of the sliding door can be adjusted to a certain degree. The vertical position can be only adjusted by a very tiny amount.
1) Remove all of screws on the sliding door interior panel, and as well as the torx screw on the open/close barbaric door handle.
2) The bottom panel, other than the screws, has 2 plastic/nylon semi-resuble flat headed holder fittings.
3) Remove the two interior rubber grommets at the rear edge of the door. This will reveal 3 adjustment bolts.
4) Loosen the bolts, then push the door a bit forward while holding the middle hinge. Don't push too much! Just a little.
5) Re-tighten the middle handle bolts, and subsequently re-adjust the striker bolt. This is a PITA to align properly.

I have a 2002 passat. It is a 1.8T. I have a stock turbo, it has a full aftermarket front mount hooked up. It also has a blow off valve. OK my issue is that I believe it runs too rich. When I drive the idle will drop and the car will stall out. It has its good days and bad days. What can I do to make this not happen? Would I have to have a recirculate the air flow again? Should I have everything stock again? Would anything else stop this happening? As well as how much PSI does this car stock suss posed to push? I have a boost meter that only reads max 5 psi. Should it be more? I am new to VW and brought the car off a friend.

I had my license revoked for a year so my baby had sit for a year with know one to drive it.. now before i had to put her in storage she ran fine no problems what so ever.. I would time to time start her up for a while over the winter but because of family problems there was a time where she sat for couple months without starting and letting her run. Now when i had the time to do it it was like i walked up and got into a whole different car, here is what i got going on....
Go to start it up and she will idle up to 600rpms then die out i would have to give it gas to try to start her but the thing is i can only go up to 2k rpms or it will just auto drop down to about 800rpms. i would usually have to floor it all the way to even get it to stay idle by her self its not as bad anymore but still does it. Also it smells like gas like crazy when it starts up,i had a half of tank when i kept her in storage so idk if its just bad gas doing this but seems like a lot of problems just for having bad gas in it, and she puts out smoke white smoke..now i know shes running rich because me and a buddy looked into it. also there is a crazy sound since shes been sitting that has never happened before it sounds almost like the belts need to be lubed up but the belts are fine and its loud from under the front bumper my friend said he thinks i blow my turbo but I don't see how that could be just from sitting for time to time.. the car and motor has a shake to it as well.
I tried to drive her up and down my hill a couple times to see if i can just break some cob webs loose or anything but you give her gas she barely once to go and if she does she get to 2k rpms then die down and hardly moves and if i floor it to the ground it takes a bit to get up and going but then drives seeming like nothing was wrong. I have never had any of this issues before I put her for storage and now i have 4 weeks till I get to roam the streets again but sadly my b5 is dying on me.

I have a 2002 Chevy Impala driving it in the city of Chicago. It's recently had the oil changed, and the transmission fluid flushed and filter replaced. This car was mine before I went off to school, and I meticulously maintained it for three years, and then my step sister inherited it. She drove it for two years, and then it sat in the driveway for a year and a half. It's got about 175,000 miles on it.
Problem: Every time I start to accelerate past 25mph and get around 2000rpms, the car starts to give out, sputter and jerk. It starts to drop off right when it should be shifting to second gear. When on the highway, even if I floor the gas peddle, it won't accelerate normally, but instead just crawls slowly to higher speeds.
It will eventually reach the higher speeds, but it takes about 5-10 minutes for it climb up from 25mph. I don't know enough about this level of car trouble to make a diagnosis myself, and would like an estimate of the cost for repairs. Also the car is getting around 19mpg on the highway, which I need to improve if I'm going to survive the $4.50/gal of Chicago gas. I'm hoping that fixing this problem will take care of that as well.
