Bruno2 Posted August 22, 2020 Share Posted August 22, 2020 91 F 150 E4OD 351W EFI truck doesnt want to idle. Truck usually dies when going from park to reverse and reverse to drive. I checked for vacuum leaks. Found a couple and fixed them. I changed both temp sensors also. No change in behavior though. Any advice would be appreciated Link to comment Share on other sites More sharing options...

Gary Lewis Posted August 23, 2020 Share Posted August 23, 2020 Whoever guessed IAC is the winner!! You know who guessed IAC. You gave him the symptoms and before you said you'd Googled it he said "IAC". However, you didn't tell him before he guessed that you'd already fixed it.
