taurus code p1131

Asked by Apr 03, 2019 at 01:55 PM about the 2001 Ford Taurus

Question type: Maintenance & Repair

While idling at stop lights my rpm will dip from normal range 750ish down to
450ish and then spring over 1000 then settling back down to normal. I can
feel an obvious sluggish shake to the engine when it does. however this is
not every day and/or every time its a little intermittent.
Error code I was told is P1131

I just want to confirm air control is 100% cause and that changing is worth
what its going cost me to have it done.

1 Answer


With intermittent issues, have to test when problem is ongoing. Unplug the maf sensor, start it up and take it for a spin, if it does better, dirty or faulty maf sensor. Check for vacuum leaks when problem is ongoing. Check fuel system, just my opinion.
