With a misfire code it can be a sensor bad as well your cheapest option is to have a pro do it to avoid unnecessary parts as well as aggravation. The port is on the fuel rail you need to remove the cap to hook up the gauge, it may require a special adapter.

Thanks for the response but if I did not want to do this myself I would take my auto to a mechanic. I will pinpoint the problem, this auto has a 3.6l motor my washing is about as big as this. Com on man referals we dont need. Help is what I need. Thanks anyway I kinda thought it was on the fuel rail but what is needed to discover it.I will send u some tamales made out of pork lol
