brian, my 04 jetta has a rough idle, not throwing a code. I notice it more on warm days. A lot of what im reading is leading towards it being the MAF. Are there any ways to check it without scanners and volt meters? thanks

[briansmobile1]

@olmattieboy None I would recommend without being sarcastic.

[briansmobile1]

@olmattieboy pull the maf sensor plug and if you feel more power then you have a bad maf sensor. I would also check out the vacuum lines getting dry rotted.

good luck

Also, if you suspect the MAF sensor to be bad, unplug the connector from the sensor and go for a drive. If there are any changes(positive) than the sensor is bad. If it stays the same, its probably not faulty. Clean it anyway.

When the MAF goes bad, the computer uses pre-defined values for air temp/density/volume sort of like a safe mode. You lose performance but it can still be driven okay.

@briansmobile1 it was a bad MAF
