Check Engine Light
Cadillac Eldorado
Ford Explorer Sport Trac
Late Model 1979-New Ford Mustangs

Why would a 1989 Cadillac ElDorado show the service engine soon warning light after the oil leak on the manifold was repaired?

probably something was left unplugged. Go to auto zone and get the codes read for free and it should tell you what it is.

I Bet You Have A Northstar Engine. Your Starter Is Under The Intake Manifold If So. To Replace This Is Nothing Short Of A Nightmare. If This Is What You Have Expect To Pay A Large Service Bill To Have It Replaced. Thanks General Motors
