Codes p0175 and p0305
Read the codes p0175 states mixture is to rich and p0305 states #5 misfire. I'm guessing p0175 is bc of the misfire. Problem is the shop replaced coilpack #5 and idle is still rough as hell. The spark plug hasn't been replaced yet and hoping that would be the cause of the rough idle. Any other ideas?

Well I guess I spoke too soon. The rough idle was corrected by replacing coil pack #5, spark plug #5 and fuel injector #5 but while driving and needing to acccelerate on the highway the truck had a major hesitation at about 3000 rpm and the check engine light started blinking. I let off the gas and the check engine light continued to blink but eventually went out. I tried to accelerate again after about 10 miles and the same thing happened again with the hesitation. At idle the truck seems like it is running like a champ but the moment I need to get up and go on the highway I feel like the whole truck is going to **** the bed. Any ideas on the problem?????? I have 132500 miles on the truck and have read about known problems with these injectors. Would these problems be covered via the extended warrenty by FORD?
GLC, I appreciate that link and will hopefully get use out of it.

Coil pack 5, injector 5 and spark plug 5 all test good bit the truck is still misfiring once on the highway trying to accelerate. The truck is fine at idle and normal driving but the moment you go to accelerate hesitation happens and still can't seem to figure out the issue. The misfire code p0305 still shows as well
