Last year I purchased a50K mile 600ES conv that is a really nice car and runs great. When it gets warmed up good, the Power Loss light comes on. The cars seems to run just as well and I have noticed no difference in performance, but I want to be sure I am not damaging the car if I continue to drive it with light on. The shop said that the code shows a bad EGR valve but that they cannot find one for it. It looks like the Chrysler part is 4287756, does anyone have any idea where I might get a hold of one? Any thoughts on whether something else might get me running without the Power Loss light coming on.
