1997 Ford Explorer Eddie Bauer 4.0L Poor Idle Quality, Hesitation, MIL Lamp on
Posted to Ford Driveability on 2/12/2004 13 Replies

Hi folks'

Wondering if I could get some help as to possible causes for repeated 153 and 151 codes for lean on bank #2.

Replaced o2 #1 on that side for slow responce but no effect. Smoke tested intake for vac leaks but found none. Fuel pressure was ok on test...
