I have a 1999 tracker 1.6l 4x4 2dr convertible, the ses light keeps coming on. When I check for codes I get p0400 insufficient EGR flow detected, what are the most common fixes or causes so I can look at first before I start throwing money at it? This has been going on for two years and now the light won't stay off for more then a day.
