B5.5 2001. When I am giving her gas you feel her stutter. But its not like a misfire stutter. Its more like a lose of power. Its almost like shes switching from boast to naturally aspirated. These stutters can also last a few seconds at a time. Where to start looking?
View 5 Replies2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?
Situation 01 Jetta AEG 2.0L codes catalyst below threshold and random misfires.
•found exhaust clogged due up catalyst. It was actually making contact with the rear O2
-replaced cat as an assembly and reset codes with Ross-tech
• start up, idles perfect no hesitation smooth. Road tested it and upon entering freeway ramp at it started stuttering/misfiring
• CEL flashed for cylinder 3 & 4. Inspected wires found #3 lost continuity, installed new wires.
•road tested and same result but only 4 came back. Swap plug with #2 and retested.
• #3 and 4 misfire came back again
- shooting in the dark to identify which way to go with it I tested:
•compression was solid 140
•fuel pressure 35 psi at idle and 45 when snapping the throttle.
-Suspicious spec is 55-72psi
•squeezed the return line to inspect if the Fuel pressure regulator valve possibly leaking excess.
Psi never went higher than 45 at idle and throttle snap to wot
•graphed the tps signal smooth with out drops or glitches up to values of 84 according to toss tech scan tool
•looking at measiring blocks one item that was odd is engine load at idle 99.5%
-swapped parts with known good parts with a good running 2002 Jetta aeg motor.
•MAF -no change
•ignition control module/ coil pack no change
-today ill be checking fuel pressure at the fuel pump and inspect if the fuel filter possibly clogged.
My independent mechanic says my radiator fan and AC fan are cycling too much. The dealer says they are not. I know it started about 6 months ago and that I get 2 miles per gallon less now. If the heat, defrost selector is in any position it happens as long as the fan control in not on off.The fans run for 5 seconds and then are off for 20 seconds. The independent says the AC has refrigerant but doesn't know what is causing it. It happens at all outside temperatures. It happens at all car temperatures. (Just started, been driving for an hour etc.)

Every time I start and put n reverse I had to rev it before i can reverse or it will die, when in drive if i barely put my foot on the gas it stutters like its not getting fuel or a misfire or something. i have changed just about every sensor there is, as well as plugs. it only stutters when lightly on the gas pedal.
*About once a month* after driving about 50miles when you let off the gas going down the road it starts loping real bad, drops about 4-600 rpm until it dies.
Just picked up a 03 Excursion limited 6.0, traded in my 04 f150 for it. Runs great- The dealer put in a new FICM and did a full tune up on it, also has stock bolts, NOT studs. I just added a SCT livewire with canned tunes, and have what feels like a misfire or stutter at high boost/ RPM. The only thing I see on the SCT gauges is the ICP hits about 22.5 and then drops off, that is with the street tune, when i go back to stock i can hit 24+ all day without a issue. Both tunes have my FICM at 48-48.5 and never moves. The ICP Duty also in both tunes will go to about .7-.8 and never drops... Is this the fuel pressure dropping from lack of the "Blue Spring mod" ?
View 7 RepliesMy 2003 f150 5.4l has developed a slight stutter when I turn from a stop or go from reverse to drive or vise versa. I had thought it was the IAC so I replaced it but the issue is still there. There are no engine codes and it does not miss fire at idle or while driving. The problem appears to be happening only when the a/c is on. Could the belt be the cause?
View 4 RepliesMy 2001 6.8 L V10 runs great all day & night without issue, but first thing in the morning when below freezing it has a hiccup. It'll fire right up and stutter and stall within less than 2 seconds. Usually twice. Third time it fires and keep running. Is there a fuel check valve somewhere on this thing? Not sure what that would have to do with the temps. Wondering if it's/there's an easy fix or not?
View 5 Replies06 250 5.4 40k on it, usually when cold and accelerating engine will misfire and stutter and then continue accelerating. The wrench light will flash sometimes but it wont store a code. This used to be vague in occurrence but has now started to be more a common occurrence even when up to normal operating temps.It seems only to misfire /stutter on hard acceleration or towing/hauling heavy loads. The only answer I got from a mech would be to do a computer reflash, not sure why /how this would fix whats going on.
View 1 RepliesI'm trying to fix a B5 1.8t Passat, it is usually a pretty quick car but recently it has had an issue where it "stutters" when accelerating. Meaning, if you put your foot down, it doesn't "take off" right away (you can't get the wheels to squeal) (not that I would try to do that normally). I know how the car used to feel, so it's not turbo lag or the ABS kicking in. It seems to behave normally after the initial stutter, it's most noticeable in 1st gear. I replaced the gas and air filters for fun, but no dice. No codes on VCDS shareware.
I can think of a few theories based on searches, but am not sure how to proceed;
- Plugged cat: expensive, not sure how to diagnose positively to avoid throwing money.
- Turbo issue? Wanted to hook up a gauge to see if the turbo is boosting correctly. Need to find a place to plug in.
- Clutch? Unlikely as the RPMs don't jump, and in third it doesn't slip. The acceleration makes it feel like something is slipping though
- ABS misbehaving? Light isn't showing up though.
I have a 00 Passat GLS.
When i accelerate, whether it's hot/cold/wet/dry outside, the car almost stalls. I have not had it stall yet, usually out of pure fear, i drop the pedal to the floor, and i catches up. I have had this happen at very inopportune times, like joining traffic. The car does a sort of stutter step.
I know little about new cars, but i feel like the fuel or air aren't making it through nicely.
When my car was brand new, in 2004, I had to take it in for its Tiptronic software to be updated. Apparently there was a Tech Service Bulletin on the 2004 V6 Passats where this faulty software caused the car to hesitate and stutter between 1st and 2nd. At the time, the problem was fixed right away at my dealership.
Now my car has 40,000 miles, and has been flawless. I took it in for the 40,000 mile service, and my car came back from being serviced with several problems mostly minor--the AM radio is suddenly static-y, the tires were all underinflated by 18 psi's. But a more serious problem is that the hesitation and stutter that I detected when the car was new 2 years ago is back! I can't believe I brought a perfectly working car in for 40,000 mile checkup, and now have these issues.
I have an 07 6speed MT w/ 82K on the clock. Today it was snowing on the ride home and I noticed a few occasions where the car felt like it was bucking for just a split second. No warning lights came on at any time. The RPMs and speed never changed when it bucked. I was driving between 35 - 55 MPH when it was occurring in 3rd, 4th or 5th gear. No correlation to accelerating, decelerating, or coasting on highway that I could figure out.
Given that the snow was covering even the treated road surfaces, I suspected it might be connected to the ESP, so I turned it off for a while. Still happened.
I didn't notice any abnormal engine noises and it was fine on my ride to work in dry conditions earlier in the day.
I haven't had any work done on it recently and I am getting the 80K service done next week. It has no engine mods done at all. All stock.
Could it have been the tires slipping on wet spots? But happening so quickly the traction light never came on? Or should I look for other issues in the engine?
I purchased a 2014 3.6 SEL from a non VW dealer. They may have put regular gas in the car, I feel like it runs weird, feel a delayed throttle response and a little stutter before acceleration? or is it just me?
View 6 RepliesThe last couple of times that I've started my W12 after sitting over night or longer I've noticed a misfire for 10-20 seconds and then it cleans up. Today the engine icon illuminated and after returning home I ran a VAG-COM scan which revealed these DTC's. There are 7 found faults at address 11.
My question is this- What exactly is causing this misfire issue? I'm assuming there is a faulty piece under the hood begging for attention but I don't know which item it is.
Everything else seems to be performing as it should but I see a few other faults showing up. Are any of those faults anything that needs looking into?

Our 2001 Passat wagon 4cyl turbo automatic has a random idle stutter. When sitting at a stop light the RPM's quickly drop and then regain idle. It happens at random times and only when idling after the engine has warmed up. It doesn't seem to matter if its in drive or park. What sensor could be failing or a possible cause? Over the past year the problem has increased from almost never to a few times at every stop light. My OBDII reader shows no codes. Car has 105K miles and I cleaned the throttle body.
View 2 RepliesWe love our Treg, but I am not happy about the clatter (like not lube for a second or two) when starting in the morning. Temps are warm this time of year. Otherwise, everything OK.
View 1 RepliesJust got a 2000 Accent DL 3 weeks ago. Every time that I try to put gas in it the nozzle clicks off about every 10 seconds. Is this normal for a Hyundai? (this is my first). If not, how to fix the problem?
View 3 RepliesI have a 2006 Sonata GLS with the 3.3L V6 and close to 230,000 miles. A few months ago I noticed that my crank time at starting was longer than typically - it has steadily gotten worse.
Now the crank time is close to 8 - 10 seconds. (Which might not seem like much but trust me, it is).
I suspected that the fuel pump was faulty, however, once started - it runs great.
I put a pressure gauge on the fuel pump outlet and found that it only kicks the pump on when the car is cranking, the fuel pump does not kick on when the key is in the "on" position. Once the vehicle starts, it seems to be drawing fuel.
The pump has all sorts of pressure, I am not worried about that.
I decided to change the Fuel pressure regulator valve thinking that maybe it wasn't holding pressure - That didn't seem to do anything.
Do I need to change the entire Fuel Pump Assembly?
1996 GMC Jimmy SLS. I've looked at the "starting issue" threads in this forum but none are quite the same as mine. When you initially try to start the Jimmy (cold or warm), it seems to just crank for 20-30 seconds before it even tries to fire. New plugs, cap, rotor, wires. Battery is 2 months old, and so is the alternator. What about the relays or starter. It's not an intermittent problem either. This happens EVERY time you start the vehicle. The jimmy sat for a good while before we bought it, but would that cause the starting issue? It seems to run fine after it starts, but hesitates (stumbles)a little coming up off idle when its warm.
View 5 RepliesI had the transmission filter and fluid changed at the local VW dealership had some issues with that but they straightened that out and its been fine for a while well then about 2 or 3 weeks ago i was trying to mess with an audi and hit the gas (has the 6 speed auto tranny) and the car kinda stuttered and the check engine light flashed probably 4 or 5 times then went off, it did that a few times after that then my wife was driving it and it did that stutter again and the light stayed on, the code said misfire on cylinder 2..
So I replaced the plugs today and it did fine at first but when i got to about 55-60 and went to speed up and it started to miss pretty bad then steadied out and sped up. no check engine light or anything but it was missing.
