Compounding Problems - 8/22/2008 6:00:14 PM    Disco C   Posts: 39 Joined: 7/16/2007 Status: online 2003 Disco 68000 miles.  Last week I pulled 2 codes P0130 and P0171.  Cleared themselves a few days later.  One week Later CEL came back on pulled P0130 and P1171.  Purchased truck 1 year ago with 62000 miles.  Did the 60000 service at that time.  Including serp belt, plugs and wires.  One month ago engine had a tick, CEL light(P0130 and P0171).  Had 2 front O2 sensors changed, engine flushed, switched to Mobile1 syn and K&N Filter.  Slight tick still there.  Also have some leaking(rain water).  Front Drivers side A pillar and drivers side Alpine window.  Been a tuff week for me and my Disco.  Any help, advise, thoughts or prayers would be apprciated!

Does your exhaust stink, how is the tranny shifting into 4th? _____________________________ Mike Retired service manager.

RE: Compounding Problems - 8/23/2008 11:07:27 AM    Disco C   Posts: 39 Joined: 7/16/2007 Status: online Just a thought.  Since im showing codes for front sensors (even after replacing front O2''s) and have the tick noise when engine warms up.  Maybe an exhust leak? Intake manifold? (in reply to Disco C) Post #: 7

RE: Compounding Problems - 8/27/2008 4:46:16 PM    Disco C   Posts: 39 Joined: 7/16/2007 Status: online So I decieded to clear the codes to see what would come back before purchasing any parts.  P0130 is the only code that came back.  Odd since the 2 front O2 sensors are new. Im stumped! (in reply to Disco C) Post #: 8
