Default MAF and temporary disconnecting...

I'm at my wits end w/ the way my car has been running the past month... my question is if I disconnect the MAF sensor to see if it is attributing to my poor acceleration then reconnect it, I should only have to endure the MIL light 'til I can reschedule a dealer appointment, right?

STFA and it seems that there should be no ill effects, however one member couldn't get their vehicle started... I don't want to gamble on this as I'm over an hour from my dealer.

Any other possible repercussions?

TIA - Kevin

Default It won't cause a MIL. The ECU will revert to the TPS....

for attempting to guestimate airflow until the MAF re-appears. That's one way of diagnosing a faulty MAF sensor.

Default so if its a bad MAF do you think it will be better to run the car with the MAF unplugged or plugged

in and giving bad readings? Just for future reference as I'm on my third MAF.

Does it run better (or at least differently) with the MAF disconnected?

??? Losing boost isn't really a bad MAF symptom. Are you sure the tech didn't say MAP sensor?
