well I'm back from my 1200 mile run. car liked it for the most part but still has the surging, high idle, running rough on start, & hard shifting to drive & reverse ( which i believe to be due to rpm at 10.000 ) But could also be due too vac line to transmission! Have my work cut out for me, & believe a fuel filter should be first. car averaged .25/mile. always use premium which is 91 octane, but run into a husky that stated premium was 94 octane.
