Yes I do have the egr hooked up. What voltage should the oxygen sensors or egr postion sensor have? I swapped back to speed density and it somewhat improved. What side is the right side oxygen sensor the passenger or driver? Should I keep it speed density if it ran ok just idle isn't all that good. I get a code for the air bypass valve now. I tried replacing it. The code went away and a map sensor came up so I changed it and the air bypass is still comes up but the map went away. The car is idling kinda funny it takes time for it to idle back down after reving it but does and then kinda speeds back up and then after a while slows back down. I am going to replace the fouled plugs but first I want to get the O2 right so they don't get fouled again.
