Willam,
IF you are a tech or owner of the shop, you can now send an e-mail to the webmaster@peachparts.com and get a pass to go to the TECHS ONLY forum.

That said, I would check the vacuum hose that goes to the manifold pressure sensor.

Also, be sure to check the trigger points that are under the distributor housing. There is 4 sets of points that trigger the injectors and the will get wet with oil. If so, clean them and dry them to see if it helps.
