In this video I work on a 2006 Saturn Ion 2.4 with engine codes P0300, P0171, P0507, P1174. The customers complaint was rough running, poor performance, erratic idle and over all just "didn't run right". Come along as I check this car out and see what is wrong.
NOTICE: Car will be returning at a later date to be repaired so check back for the confirmed fix :)
