Needing to change plugs and have read all the stories. Still think with proper tools I can handle the job. My question is about accessing the passenger side rear plug (#4). It seems to be deep towards the rear of the compartment and if it becomes a breaker when I remove and needs to be removed with the Lisle tool, do I just start removing hoses and the PCM connectors? Or do you guys know an easier way or mechanics trick to get to it?

 

Hey everyone, I tried to change the plugs on my 2004 4.6L, got everything but the ones against the Fire Wall, #4 & #8. I see the Fuel Tube is in the way. I'm not a mechanic in any sense of the word.

Truck is running somewhat ok, sluggish and stalls at some stops or making turns. Is there any way someone could post a step by step procedure to checking MAF, O2 sensors, etc. Thanks Jeff

 

to get at plug #4 you need to disconnect the plugs and remove the control box on the firewall as well as the bracket holding it to the firewall.I have no problem getting at #8 plug on my 5.4 but I used the one piece socket and extension to get at it after removing the COP's

 

Thanks 390XR7 for the reply
