Post subject:  MAF sensor test?
so after doing EGR delete and re-flashing the ECU back to stock I started getting MAF errors. I've double checked all hoses and connections, everything is tight. I've cleaned the MAF and replaced the MAP sensor because it was beyond salvaging, even at 65k miles. It boggles my mind that the stupid thing would go out. Does anyone have resistance specs for the MAF sensor so I can at least check that before I shell out a Franklin to replace the stupid thing and turn off the light? :furious:

thanks

Its normal to have a maf error with an egr delete and the stock tune.

I guess I should clarify. "stock tune" meaning Nick's 811 FCV and EGR delete tune.

well, I tried cleaning the MAF with a more aggressive cleaner and now it seems happy. Maybe the increased airflow from the EGR delete was just enough to send it over the edge? at any rate the CEL is off.

Ahh gotcha. If you have an android phone or tablet you can get a bluetooth obd adapter and any number of apps on the phone will read the obd data for a few minutes before it locks up. I use the app Torque Pro, but there's a free basic version. You can read live MAF data that way and see what's up. Idle should be 15-20 g/s depending on altitude and full throttle will go well over 100.
