Cam Position Sensor?
'00 E250, 5.4 gasser, 260K miles, fresh plugs but Granatelli COP's....
During cold snaps at first start I get misfires with rough idling---turning motor off then immediately restarting smooths it out, never again recurring that entire day. CEL is on, code scans say cylinder misfire, typically P0351 through P0358 almost random each time this happens When weather never dips below 45 or so this condition doesn't exist at all.
I'll be swapping out the Granatelli's for my original COP's but its been suggested by a trust mechanic the CPS could be at fault too. Anyone have any experience with this or direct me how to better diagnose this?
TIA!

Yeah LxMan1 that's the first step obviously. For the life of me I can't recall if I ever had this condition before installing the Granatelli's. I'm sure when its all said and done I'll have learned my lesson about non-OEM parts on Ford modular motors.
I'll report back in case anyone else is watching this topic.
Thanks again
