    Look for a vacuum leak, an air intake issue with umetered air getting into the intake manifold (broken air box, damaged air tube). Could have an exhaust restriction. Could have a fuel supply issue.

    Start with the vacuum leak check - visually make sure all hoses are connected as they should be and the air box is intact. Then do a base fuel pressure check, followed by a bleed down test. Last, have the exhaust tested for restrictions.
