New plugs wires coil crank shaft sensor cam shaft sensor. After I put new crank shaft sensor on the code still.came up and lean on cylinder one and misfire cylinder 3. Check fuel pressure all good and seems like all injectors working good. Car has 196xxx miles also has has new heticle gear on crank for oil pump and Gage. I believe the problem is the harmonic balancer pules ring but don't now to much about that.
