01 2.7t

 

I believe you might need and ICM (ignition control module). I know NOTHING about the 2.7's (or the 4.2 for that matter) but I believe they have an ICM and it is in the air box.

 

2nd on the ICM.

There are two on the top of the airbox. Switch the brown connectors with the black connectors to see if the problem follows the ICM - reset and look for misfire on cyl 5. If it is on 5, you have a problem with your ICM. If you are handy with a soldering iron, pry the top off the ICM and locate the broken connection, clean out the goo and solder it back together.

 

it was the icm now about prying off he top i dont see that possible

 

The rectangle with the rounded corners and the writing comes off. Use a knife to get it started then a screwdriver to lift it up. Nothing to lose at this stage - could save $200 if it is a loose connection (usually is from what I can gather).
