Oldsmobile Intrigue Check Engine Light Due to Gas Cap Issue
Oldsmobile Intrigue Problem
Model Year Affected: 1998

I had the vehicle in for yearly State inspection. Check engine light had been coming on after ignition and then going out after a minimum of 1/2 of driving. In order to pass inspection cause and repair had to be identified. $1100.00 later new gas cap solved the problem.
