2004 F 150 won’t idle
I have a 2004 f-150, Triton 3 valve engine. It runs great at speed but dies at idle. I get these codes:
PO 171
System to lean bank
PO174
System to lean bank 2
P2195
Stuck lean
P2197
Stuck lean
I’ve replaced all four o2 sensors, cleaned the mass air sensor and ran a bottle of cataclean thru it and still dies at idle and the same codes come back. The truck will idle until it warms up to running temp. Any help would be appreciated👍🏻
