Hey guys I recently purchased a used 2010 f150 4.6 v8 Triton 3v, I replaced a cam position sensor and the vvt solenoids to eliminate a issue with the truck idling rough when I come to a stop, the issue stopped for a few days and now has returned, any ideas or help?

 

Vacuum Leak? Check all hoses and make sure nothing is hissing.
Spark plugs? How many miles on the truck? When is the last time spark plugs were changed?
Any codes or CEL?

The more details you can provide about your vehicle (perhaps add to your profile signature), the more everyone here can assist.
