So all of a sudden today.. My car was acting weird... I thought maybe since it was around 90* here in NY maybe that had something to do with it...

Car felt like it was bugging.. and all of a sudden randomly just turns OFF... It happened about 6 times today. From 1PM - 5PM... It would not turn off when I was driving the car normally / cruising.. only when I would come to a stop.. or when taking a turn when down shifting

I went to get the codes read.. here is what I got..

P1111 MFR control Fuel air metering

P1136 MFR Control Fuel air metering ( got it twice )

P0327 Knock Sensor 1 circuit low input bank 1 sensor

P0300 Random/multiple cylinder misfire detection


What do you think this could be??.. Iam so scared and frustrated right now.. Iam going to check into them tomorrow.. take the plugs out etc. Whatever that needs to be done.

Car has been running perfectly fine until today.

My AF was always 11.2-11.3 at WOT
I have an 03 6 MT


Thanks for any help fellas!

 

I'm assume, failing MAF or there is leaking somewhere. And keep your eyes on knock sensor, if it comes back on you might have a bad knock sensor.

 

chef,

How much would a new MAF and knock sensor run me? do you have any idea?

 

When did you replace to new? Who installed them?

Most of problems I have saw and read, pretty much bad harness. Knock sensor itself usually won't go bad that easy, I do remember _jb had knock sensor light on, he found out harness was messed. It is really hard to point at one. P1136 is related with fuel trim too lean. so I would say, its good to start from leaks and check all the wires. I heard from few people said that they had p1111 issue when they had dirty oil. But this is just hearing from people.

I wouldn't just clear it and give a try again. Sounds like something wrong somewhere.

 

wow that could get expensive.

just reset it all and see if they come back

 

Sounds like a bad connector, ground or harness.

 

hah yeah no kidding..the MAF sensor alone is like 300... which way should I go about reseting them? taking the Negative out of the battery.. or do the pedal procedure ?

Thanks guys!

 

If you are looking for a MAF sensor someone is selling one with the housing and all on Driver

I bought a maf off ebay for like 50-75 bucks brand new. I bought it because I thought mine was bad, turns out it wasnt. I thought it couldnt be an oem quality unit. But when I received the maf it looked EXACTLY the same down to all the little serial numbers and strange symbol. I usually stay away from ebay shat but it was worth a try and I am still using the cheap sensor works good.
