Vag: P1114/17522

[biketsai]

Just pulled the codes off a friends B6 1.8.
I got those codes with some symptoms:
7522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 35-10 - - - Intermittent-misfires on all cylinders
Symptoms:
- lack of power
-checked plugs already
-rough idle and drive
-block 32 values are in spec
When I disconnected the MAF it idled fine.
I'm thinking its the MAF
anybody wanna chime in?
-thanks

Take your maf, put it on his car, see if it runs ok. If it does then you were right. If it doesnt then you saved him from buying a maf for no reason

I drive a b5

Well, now correct me if I'm wrong. If you disconnect the MAF, the idle should stumble a little bit right?

Symptoms: rough idle and drive

This contradicts your statement of, "When I disconnected the MAF it idled fine."

Try looking things over again. And off topic real quick. How old are you? I'm curious because of your use of the [Enter] key after ever sentence / expression instead of the [Space Bar]. I'm guess fairly young because you've got the whole "Instant Messaging and Text Messaging" habit down fairly well. I’m not trying to be a smart ass, I’m seriously asking this cause there's a kid on another local forum that I frequent that does the exact same thing as you. I'm just noticing a trend... an annoying one at that

The idle was a tad bit off, but I was just explaining the symptoms of the MAF and how the car performed with it disconnected, not try to cancel it out.
Although I am 17 years old, I kinda feel insulted by your reply. I simply made the thread in that manner so it was EASIER to read, organized, and I LISTED the problems so you didnt have to search around my thread wondering what is going on.
But this is just for you, hopefully you can read it better....

^^I get a headache just trying to put together what I wrote.

Dude, I was just referring to that lil portion at the end. The itemized listing of symptoms was fine. And it's just something that I've noticed from the younger posters that's all. Back to your fault codes, I would start with replacing the O2 sensor. I say this based on the "Internal Resistance is too High" fault.

As for the MAF and when you disconnected it, I still believe when you did this the idle should have gotten worse or stumble. Now with you saying that the idle was fine/didn't change when you unplugged the MAF; that tells me that your perception of a "fine" idle is a bit off. The engine shouldn't idle fine with a disconnected MAF (I may be totally wrong here, I'm hoping someone that knows for sure could chime in). Now if the idle is off and you disconnected the MAF and the idle didn't change, then yes that is a sign of a failed MAF.

The car will idle fine with the MAF disconnected. The ECU will switch to default maps.

That is the post cat sensor which shouldn't effect mixture. Flashing CEL? What version coilpacks?

[biketsai]

Yes, there was a flashing CEL, so you say its the second 02 sensor?

[skeeball]

Sounds like coilpack(s). S2 is the post-cat sensor. I don't think I've read about coils or a MAF causing a 17522 but it could be. If new coilpacks don't fix it, that o2 sensor might be bad also.

Log the MAF readings and see if they look funny. I wouldn't jump to replace that though without more evidence.

[biketsai]

coilpacks it was

Glad you got it fixed.
