While in park, my car will idle normally and then after a few seconds
it will idle extremely slow and begin to shudder as if it was going to
die on me. It happens worse if I happen to have the AC going. Check
engine light was on so I checked the code and got back P1131. What
gives? I've done some searching around and have only gotten mixed
signals about my o2 sensor or my fuel filter or a vacuum leak. How
can I check those and how much would it cost?
I.A.C. idle air sensor and a vacuum leak from a vacuum hose that
gets a hole in it from melting and rubbing from vibrations of the
engine. Vacuum hose is in back of engine bay .
