P1140 Code Help! (After speed bump) I was going out of this shop which has a narrow road and there was this hidden bump that I hit, Immediately the car has been misfiring or just feeling sluggish. Parked on a parking lot to check real quick, no damage underneath. Drove it back home and diagnosed it down to the Code P1140 (or INPA 121 Load Management/Height/Load Adjustment). When its running the maf is at 20KG/Hr in Inpa and the engine just makes a off noise, I thought if its a bad o2 sensor but it points more towards a maf sensor. I wonder if its more so a vac leak perhaps? Any ideas?? |
