Passat (B5) :: Engine Rough Idle - MAF / O2 Codes P0103 And P0134
Oct 6, 2010
I bought a 1999(b5) passat, 1.8t(AEB) 5spd, came with a DIRTY K&N so i cleaned it with the cleaning kit....
Car drove fine, then: started it up after an hour or so.. it was idling rough, then would spike(17-1800), idle rough, idle fine, spike....etc. just random. it went away for a few minutes, so i tried to drive it home... got 1/8 mile into 3rd... and car just bogged down so i slowed to stop and turn, went to go, it was idling rough so i couldnt drive, just "hobble" into parking lot.... i let run, more random rough, spike, fine... so i let it sit, off. when i returned, it was the same, but now CEL light on...
Codes: P0103 - Mass or Volume air flow sensor circuit high input
P0134 - Heated Oxygen sensor - bank 1 sensor 1 (H02s11) sensor circuit no activity detected

So I didn't pass the smog check for the new used car that I just purchased 10 days ago. Although my old car (same model), was five years older, I never had this problem. I was told that it is a gross polluter. These are the problem that I have to fix:
OBD Fault Codes - P1128 Manufacturer specific codeP0411 Secondary Air inj Incorrect FlowP0172 System too Rich (Bank 1)P0134 O2 Sensor CKT Inactive (Bank 1 Sensor 1)
How this happens?? 2001 VW ...

I have a 2006 Chrysler Sebring Convertible 2.7L engine. Replaced water pump and spark plugs. We triple checked the alignment on the chain and are sure the timing is fine. Car started right up. Now running rough idle and engine light comes on. Codes read misfires on 1, 3, and 5 cylinders.

124k, original owner, no mods. Car was running rough and stumbling a bit. A bunch of codes came up. I replaced coils because I had them, spark plugs look good. One code came back p0103. I cleaned the throttle butterfly and replaced the maf sensor. Still same problem.
When I first start it cold it idles high but stays running , once it warms a little the idle drops and then it won't stay running. Then the traction control light comes on and then the cel. I checked for a vacuum leak but came up with nothing.

When exiting off the freeway and stopping at the light, my car felt as though it was bucking and idling very rough. I put the car in Neutral and it subsided a bit but the lit gauges were pulsing with the idle. It felt as though the car was going to die. I put the car back into Drive and it drove fine. I pulled over and shut the car off. There were no warnings or any other indicator lights on during this time. After shutting the car off and leaving it for a couple mins, I started it back up and the engine light was now on steadily. The rough/bucking idle was present as well. I ended up driving the car to the dealer where it is now being diagnosed and I haven't heard back.

I just had my check engine light come on and checked the codes and they were P1136 running rich at idle and P1250 low fuel level. My fuel level is 3/4 full and I just installed a K&N panel filter in the airbox. While I was installing the filter I also cleaned the mass airfow sensor and then cleared the codes. The codes have come back after 2 days.

I have a 2000 VW Passat with the 1.8L turbo. When I bought it, the timing belt was off 1 notch. After I fixed the timing issue the car still didn't idle well. I was told that the throttle body was causing the problem so I replaced it. The car ran good for about 5 minutes after I replaced the throttle body. After I hooked up a OBD-II scan tool up to it instantly started running rough. The car runs at 1100 rpm at a cold start-up but when the car warms up it idles down to 850 +-75 rpms. I cleaned the MAF sensor, and it still runs rough. Car has 180,000 miles and MPGs are also down.

Driving home from work this evening and engine light lights up, also car started to idle very rough.... long story short got the car home and checked with vag com... 2 engine codes
000768 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - - MIL ON
Freeze Frame:
Fault Status: 11100001
Fault Priority: 2
Fault Frequency: 1
Mileage: 86567 km

After looking around online found out it could be a variety of reasons... gonna change spark plugs tomorrow hoping that's the problem... next cheapest fix would be the ignition coils... I'm just hoping its not internal, like piston or rings.
It's a 2007 Passat Wolfsburg 2.0T.... just went over the 53k mark.

I now have a p0011 code on my 2001 passat 1.8t aug. this is a thinker because right before the test drive around the block i did the following
- coolant flush
-replaced the fuel filter
-cleaned the knn air filter
-rotated the tires
-oil change with new castrol 5w-40 syn. and 1/2 a bottle of lucas syn oil stabilizer.
With a few phone calls a possible cause is the timing chain skipped a tooth cause of the lucas being to thick, other cause could be the tensioner finally went out?
Right know the car car has a rough idle and seems to be finding idle , and a noise from the engine around 4000 rpm.
I am waiting for the engine to cool off before i open her up to check timing.. if the chain is off a a tooth what could be the cause?

The 2001 Passat 1.8lT has an engine warning light on and feels like it is running on less than all four cylinders.( very rough idle) This is the first time we have seen this particular warning light and the manual suggests that it has a problem with the catalytic convertor.( 170K miles on the car) The car had no symptoms until the light came on today and the car was serviced last week. ( oil change and new tires) It seems that every time I take the car in for service something goes haywire shortly afterward.

Wifes car began to idle very rough and check engine light began to blink and beep, I took it to the mechanic today and he informed me that my control module was no good and it was a $400 dollar piece. I said go ahead get it done, cuz she needs the car and i couldn't afford to not have it done immediately. Question I have is does this small-ass piece really go for that much on average and what control module is it?

I've got a troublesome misfire in a 2007 Sonata V6, 70k miles, which I have been trying and failing to track down for a long time.
More than a year ago, the owner of the car complained of rough idle. When this was first mentioned, I looked at the car, she and I talked, and I concluded that she hadn't changed the oil in some 20k miles. ...... Nothing else seemed wrong. I changed the oil, thinking that what she needed was an oil change.
Some time later, I was in the car myself and all of a sudden felt a strong bucking. Must've been a misfire. I recommended taking it to the Hyundai dealer, thinking the so-called 100k mile powertrain warranty would cover whatever it was (it didn't but whatever).
We drove it to the dealer. The dealer firstly informed us that the CEL had burned out, so we had missed some codes. The dealer further us the car needed new plugs and replacement of both upstream O2 sensors. Here was what the mechanic wrote:
"BETWEEN 35-40 PUT CRUISE ON AND WILL FEEL. CHECK AND ADVISE COMES AND GOES. MULTIPLE CODES STORED IN SYSTEM. ... P0300 RANDOM MISFIRE (ACTIVE), P0140 O2 SENSOR CIRCUIT NO ACTIVITY, P0154 O2 BS S1 NO ACTIVITY. WATCHED O2 VALUES AND FOUND ERRATIC READINGS. FOUND TSB 10-FL-012 SUGGESTING REPLACEMENT OF BOTH UPSTREAM O2 SENSORS. RECOMMEND COMPLETE SYSTEM TUNE UP FOR RANDOM MISFIRE. HOWEVER MISFIRE COULD BE RELATED TO O2 ACTIVITY.
So the owner went to a different mechanic and had the plugs, upstream O2 sensors, and one of the downstream sensors replaced. All OEM, I believe. ($$$!) (O2 sensor parts 39210-3C100, -3C200, and -3C400) Dunno why the downstream one was replaced, not my doing.
Following this, there was no real improvement. No codes either. The problem comes and goes, so maybe I thought it was fixed, but it has come back. Sometimes, it can be felt just slightly when the car starts cold. Other times, it can be felt just barely when driving at a consistent speed. Sometimes, the problem becomes really bad and jerks the car around. Other times, nothing.
What to check next? Coil packs? Intake manifold gasket? She never gets "top tier gasoline," but I would be skeptical that that's the problem. These are the top three suggestions I've heard.

I have a 2004 Explorer with the 4.0L SOHC V6.
I was having some rough idle and a P0401 code for Insufficient EGR Flow. In the process of investigating the EGR valve, I had to remove the throttle position sensor to remove the EGR. After re-installing everything, I had a worse rough idle and I again removed the EGR valve; however this time instead of removing the throttle position sensor, I removed the entire throttle body assembly.
After re-installing everything again, I now have very rough idle and no pedal response. I have the following two codes:
P2104- Throttle Actuator Control System Forced Closed
P2112- Throttle Actuator Control System Stuck Closed
I did not unplug any harness, and all connections are secure. I did not remove the battery cables while working on it, but I did remove the negative cable for about 45 minutes after getting the P2104/P2112 codes hoping a reset my fix things.

I have an 2004 Santa Fe and im having some Mass Air Flow Sensor problems but I dont know what's wrong. My engine light came on for the second time after awhile. And I got it checked for the code and of course it was my sensor again. The first time I just giggled it around and the light went off. I did the same thing today with giggling it again went off. So I feel like it might be a loose connection but I really hope it isn't failing because im pretty sure that's uber expensive to fix.

My car has had a rough idle (no MIL). Scanned for codes and got the following:
P0552 - Power Steering Pressure Sensor - Low
P0553 - Power Steering Pressure Sensor - High
I'm picking up the part at the dealer this afternoon. I printed out a diagram of the component location, and it looks to be easily accessible.
