did you ever fix this issue??? i have same issues?
my car also has new plugs and wires on it... but im not sure if that is the cause of the issue or the aftermath of someone unsuccessfully trying to fix it.
***UPDATE,,, I fixed my issue,,, it was a short,,, previous owner replaced the plugs and wires,,, and a few weeks that's when I bought it,,, then later on the metal on the o2 sensor got hot was shorting out on the rear drivers side plug wire, as they were touching. So I fixed the plug wire and tied them back from each other. thanks for all the help anyhow.
