Hi guys, I just got my wife a 97 Cadillac DeVille. It has 189k on it and the engine was replaced at 80k with a used engine which had 30k on it. I keep hearing horror stories on these things. How bad are they really?

It had a miss in it when I picked it up Saturday morning. I replaced the plugs and wires, air filter, changed oil and filter, and repaired a hole in the inlet tube from the air filter to throttle valve. I also cleaned the MAF sensor while I was there. The miss went away and it runs well. As long as this car makes it through to summer next year I'll be happy.
