1998 Oldsmobile Silhouette Premiere 3.4L Excessive Emissions, Misfire, Poor Fuel Economy
Posted to GM Driveability on 11/6/2004 12 Replies

Thanks in advance for your help! We brought this van in with code P0300 set, Customer said when she started it up cold she could feel it miss. Now it runs pretty good except for the fact that the PCM is trying to subtract fuel at idle as noted by the fuel trim...
