And you might look into an OEM oil filter and maybe a bit of Marvel Mystery Oil to help out with the lifter clatter. >Isn't this just normal for >a motor with 150K miles? I don't know. >Would a broken lifter be able to cause the very >noticeable cutting out and surging problem? I don't see how. I don't even see how a lifter could "break" under normal circumstances. Get sticky, yes. Depending how it stuck it could fail to open the valve to specified height, or even conceivably open it too far/not let it close entirely. That last might cause some expensive trouble with valves and seats, I guess. But it ought to be consistent trouble, not what you're talking about. > I thought the problem was with >the AFM or the injectors and an experienced mechanic with access to the >proper analyzer could come up with an answer, but I feel I just wasted $180.
