Hello and Welcome to Justanswer,My name is XXXXX XXXXX I am here to try and assist your with your question.In most cases the problem you are describing is caused by a large vacuum leak and in most case on the 4.6 is caused by a leaking vacuum supply line to the PCV valve. Take a look at the line from the PCV valve to the intake where is connects.
is it on the pass side valve cover?
Yes that is correct
Thanks, XXXXX XXXXX that route and give it a try tonight. Can't get into it right now. Have a nice day.
Your very welcome, thank you as well.
