Help!!!!! Knock sensor and fuel trim codes
I installed a new thermostat last week, last night I finished replacing my valley pan , oil seperator and back hoses. Now I am having codes from the peak meter that weren't there before!! They are 06 , d4 knock sensor cylinder 5-6 , 06, 1b fuel trim ol additive cylinder 1-4, 06 , 23 fuel trim ol additive cylinder 5-8. Someone please help! Also will it hurt to drive the car with these codes? It seems to be running good. I am also still bleeding the system . Thanks , Tal.
