I just got done re-installing a new engine and was having probs with it. the symptons can be found here https://www.rx7club.com/forum/showth...hreadid=165963

somebody mentioned that the fuel temp sensor can cause the high idling with the PFC. i just figured i would post in here to see if that is true or not, anyone got any ideas? thanks guys and sorry for the kinda double post, i just really need some help
