View Full Version : check engine light

01-19-2012, 06:12 PM
My 90 all trac has a small leak in the intake manifold gaskit, thus creating an idle issue. My check engine light came on code 2 5 (excessive lean air mixture) but my car is running really rich. My wideband o2 comes in later this week, should I be concerned over this.

Is the easiest way to change the gaskit by pulling off the head?
