Acclaim rev. sw.

I installed Bosch Platinum spark plugs in my car about a little over a year ago (about 12K miles). I thought I was being nice to my car getting platinum plugs, but those little platinum tips ended up becoming my problem. Now the past week the car has been running poorly. I pulled the plugs and 2 of the 4 had the little tiny tip fall out. At the end of the ceramic, there is/was a little tiny tip in them about as thick as a pin and apperently just slightly deeper(compared to thickness) that was about flush with the ceramic. The plugs were still firing some, jumping the slightly larger gap, but the engine was definatly missing some. Should I be worried about the 2 tips that fell off in my engine? Do you think they got blown out in the exhaust? Could they have gotten caught in the rings and scored the cylinders? Caught in the cat? Upon some reading on the internet, I read that Bosch Platinum tips have the tendency to fall out in Turbo charged cars. Although my car isnt turbo'd it still doesnt speak well of the quailty. The plugs with missing tips were on cylinders "2" and "4", labeling the cylinder farthest on the drivers side as 1 and the farthest cylinder on the passenger side as 4.

I have a 1991 Dodge Dynasty, 3.3L, 6 cylander, AC, with 90,000 miles.It starts great then goes for about 3 blocks, then dies. It won't start again until about 30 minutes has elapsed, then its good for another few blocks. No check engine lights come on. I performed a self-diagnostic test twice and the car coded at #32 both times. According to the chart I am having problems with my egr valve/solenoid. As I do most of all automotive repairs myself, I am not afraid to tackle this problem by trying to clean the carbon from the valve, or replacing it entirely..........but I can't seem to track down its location under the hood. By going to different web pages, I have found pictures of the valve itself (for replacement purposes,) but they still have not led me to its actual location. (I have not even found it on the Mitchell web page, and that scared me.) Can someone out there point a "clunky girl" with dirty fingernails in the right direction? Also: Because I just love this Dynasty so much, about a year ago I purchased a 1992 Dodge Dynasty 3.3L, 6 cylander, AC, that had its undercarriage damaged in an accident. I have used this car as a "parts pool" for my 1991 because most parts are interchangeable. From what I have learned in my quest for egr valve information, it appears that my 1992 egr valve will work in my 1991 car. Is this correct? Any help would be greatly appreciated.
