Car Boggs down at 2000 rpm

Asked by GuruNB9QN Oct 24, 2019 at 07:06 AM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

I accidentally drove my car with the air filter box open and since then it won't
run past 2000rpm , when I try to give it gas it Boggs down and starts running
real rough and sounds like it's loading up and sometimes will stall . It idles
fine it didn't have any symptoms of any kind and ran perfect until I drove it
with the air on open . I changed the map sensor and the mass airflow sensor
and it did not help

Maybe you swallowed a critter! They like to hang out in warm places like this and got a shock when you tried to start the car. Any visible teeth, hair and eyes in the intake?

Did you unplug an air flow sensor? I would clean the MAF and throttle body in case they were fouled with unfiltered air.
