Can Running without mass airflow sensor cause long term problems?

Asked by May 28, 2017 at 03:20 PM about the 1995 Mitsubishi 3000GT 2 Dr SL Hatchback

Question type: Maintenance & Repair

My car backfired threw the cold air intake an one of
the silver filters blew out an since then my car will
idle but if I give it any gas it will bog down an stall.
But if I unplug it it runs fine. Will keeping it
unplugged cause long term problems?

It will throw off your fuel trim and continue to cause driveability issues. I would suspect your fuel mileage would suffer as well. Would suggest pulling codes or have a local shop determine what the root cause is here. Good Luck!

Agree with bryan,it is controlled by computer meaning air flow and gas,have it checked by a pro to know your issue,


If runs better with mass unhooked then the mass is probably damaged. Your air fuel mixture will not be correct running with it unhooked.
