code p071 with rough idle
I have a '97 f150 with the 5.4. It is running rough at idle and throwing code p071 (lean bank 1). I plugged the hose that goes from the IAC to the throttle body inlet and it smoothed right out. I had good suction on the hose though. Is it a problem between the MAF to throttle body? Thanks, DOn
