broken injector caps

[873.8Turbo]

I pulled the injectors out of my car and on the way out broke two of the orange caps on the tips of the injectors. Can i get these at a parts store? I figure I could get them from the junkyard if no where else. does GM sell them?

also my exaust valves and spark plugs are red in color. What does this mean, running rich/lean? too hot?

napa, checker, vatozone etc all sell the caps... i think napa in my area is the cheapest for them like 1.75 for the little kit. it comes with the caps and new o rings.

as for the plugs http://www.gnttype.org/techarea/engine/plugs.html


that should help!
