My 95 f150 5.0 has problems idling particularly on hot days. The idle after warming up gets so low that you can hardly tell if it is running. On hot days after warming up it will sometimes stall at traffic lights if I dont keep my foot on the accelerator. Codes that I retrieved are 124, 334, and 157. Help!

 

how is your air filter and ground connection?

 

Air filter is new. As far as the ground goes, I have a good connection at the battery.
