Hi, Engine man. light came on, a friend plugged it in and came up with this...."confirm manufacturer specific P1131 & P0171" and that's it showing no faults. Does anyone know what these codes are or any info. would be helpful, THANKS!! :?
Great, thanks for the quick response!!.........that's reminded me that a few months ago the EML came on and showed "o2 censor slow to react" sounds like it could be related?
