P0170 Fuel Trim Code
Have a 2006 XC-70 with 180K miles on it. 2 months ago I replaced the Mass Air Flow Sensor with an aftermarket version to clear a P0101 Code. I also replaced all 5 spark plugs and coils 6 months ago. Now I am experiencing rough start and idle, usually the 2nd start of the day and CEL comes on. It will clear for a day, then come back. It is showing a P0170 code, Fuel Trim (Bank 1).
Any suggestions greatly appreciated.
