I have a 96 Cadillac Seville SLS with a 4.6L Northstar engine. I bought it used and occasionally I will go out to my garage and the car will be running I have never seen anything like it. Has anyone out there ever encountered this problem or can you direct me as to what the problem may be!!!!!! Thanks in advance for your help.
**Note: I do NOT have a remote start on this vehicle...that I am aware of**
