I did this to mine last summer. The worst thing was getting the plug wires off without breaking them, not much room to twist and pull. I got to mine from the top after removing some air hoses and AIR switching valve. Be careful with plastic lines that may be brittle. Time, about an hour.

Spark plugs in a 2003 Cadilliac Seville need to be replace, how difficult?

It's not difficult at all. You have to remove the big manifold cover. Once that is off, then the spark plugs should be easy to get to. remember to twist the spark plug boot 1/2 turn then pull on the boot. 11 Ft/Lbs of torque when you install.

I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer
