How hard is it to replace a PVC valve on a 1997 F-150 with the 5.4 motor 4x4

 

Takes about 3 minutes. Its on the pass. side valve cover. Pull it straight up and out of the valve cover, then pull it out of the vaccum line. Stick the new one of the line then stick it in the valve cover and your done...

 

Okay,

I replaced the PCV Valve this morning and I still had a rough idle. So I thought what the hell and went and bought all new O2 Sensors and Monitors and replaced them and that didn't fix the problem. What else could the problem be? After replacing all this the check engine light went off and has not came back on and the truck is still idling rough. I don't know what to do now. Please help me!!!!!!

 

Clean the IAC and TB.

 

Maybe vac leak some where?

I'd check the hoses leading to the throttle body & elbow. I know the T in the back is known to crack.
