Had air intake system installed on 4.6 motor and codes showing lean on both banks made engine light come on. Computor was completely erased and truck ran very erratically stalling when slowing down to idle. Have run about 100 miles and is better idling but rpm still low. Am not sure if plastic small box with inlet/outlet hoses is right way round (over DPFE) does this matter got any suggestions.
