Engine Performance problem
2002 Oldsmobile Intrigue 6 cyl Front Wheel Drive Automatic 86500 miles
I understand all the issues regarding the Intrigue and its air pump and associated valves and water intrusion. What I would like some info on is what would cause the pump to come on while driving, long after the engine has warmed up? From what I have read the pump only comes on during engine start-up to force fresh air through the exhaust to reduce emissions. Lately, I have noticed the pump cycling two or three times during a trip followed by the SES light coming on. The light then goes out after several trips. Why is the pump coming on during normal driving conditions?
have the same problem?
