Thank you for the prompt reply. I actually read your article before I posted. First off, I am not a mechanic and do not have diognostic tools. I can do some basic stuff but I am better at paying others to do it for me. I was hoping that since I just replaced the plugs before this happened that it would point to something like a hose or sensor I might have knocked loose. I did not want to just start replacing parts (O2 sensors) until the problem went away. Just to give you an idea, i understood about 70% of your post (I'm an electrical guy not a car guy). Thanks again!
