MAF Sensor

[BRZ71]

Truck has been running bad, well kind of rough and felt like it had a miss for about a year now. Took it to the dealer and they blamed it on my exhaust, BS. That is what I though then, but began to beleive them because I never had any codes, etc. Well last week the thing started surging when cold and finally today started and died, pulled the code MAF sensor was bad. Replaced the sensor, truck idles so smooth I almost cant tell it is running. Just to let you know if you have a rough idle and have tried everything else, as I did, you may want to check the MAF. Mine looked perfect, so I never thought it was the problem.

You running a cold air intake ?

[BRZ71]

No, Stock all the way. Except the muffler is a Magnaflow. Had them cut out the stock and weld in the Magnaflow.

not to put words in TEE's post...how about a K&N or other reusable filter using oil?...I think was what TEE was getting at.

How much was your maf sensor?

[BRZ71]

No, regular paper filter. around 79 at Autozone, it is a rebuilt Delphi.

Just for info, if you buy it at the dealer, it's like $200.00!

[TEE]

I can't see what the exhaust would have to do with the MAF at the other end ?

[BRZ71]

Well problem is back. I guess it was not the MAF after all. does anyone have any other suggestions on what other things could be causing that problem?

I'm not a fan of remanufactured parts.

[BRZ71]

Me neither but, the price was right. although that was not the problem. I am going to post int he GM tech forum and see what he comes up with.

The "Crankshaft Position Variation" may need to be relearned. Not sure if an aftermarket scan tool can do this, but the dealer can.

 

When you say you have tried everything else, what would that consist of?
