In addition to the above work , replaced engine mounts, still rough, tried to adjust rack and it smooths out somewhat but does
not seem to hold adjustment, can the rack bolt become faulty or is this more likly a internal injection pump problem? car runs great, starts well when cold or hot, good milage 25-29, has good power. Thanks
