Hi
I noticed my car had a severe hesitation and lack of power when I stepped on the gas last week.It's got a 2.4 with 150000 miles on it. I took it to AutoZone and had the codes read. They came up P0107 and P0172. When I looked them up the first one was MAP sensor circuit low input and the second was System adaptive fuel too rich. I changed the sensor and replaced two vacuum hoses, no change.... The problems still there but my idle has smoothed out. I can drive the car as long as I don't go over 2500 rpms but there is soot inside the tailpipe now from my trip to the parts store and back. Has anyone else had this problem before? Thanks for any input.
