Guys I took a quick look at lunch I didn't see a egr valve any where.. the ole girl got 170,000miles now. My edge programmer says I have a random miss fire code. I have already replaced all the coil packs wires and plugs. The only thing else I know to do is check the egr valve, converters, and fuel pressure.. 3a130e273993a61dbb82bdde0139a144.jpg41960c47815af76455870e8f4523da65.jpg
