Ijust bought a 1989 Cadillac Deville last night. The gentleman said it
belonged to his father who is in a nursing home for the last 3 years. He
said he started and drove it once a month. On the way home the Service
engine Soon light came on. Is there anyway to find out why and is it safe
to drive. There's 56k on the car. Thanks, Mike
First, check the gas cap to be sure it is present and tight.
That light usually indicates something amiss with the emission controls.
If your locality has mandatory emission tests, you will have to get it
If not, it is probably "safe" to drive.
I recommend a visit to a Caddy dealer for a general check-over.
My guess $200-$300.
I own a '90 DeVille. The "Service Engine Soon" light has been on since
the day I bought it six months ago. I have had no problems with the car. I
also have a '87 Fleetwood. This car I have had for over two years. When I
bought it the "Check Engine" light was on. I asked a friend about it (he
owns and operates a repair garage), and he said "Oh that... My truck has
that same light on in it. I put a piece of electrical tape over the light
because it was annoying." OK, so maybe his advice was a little flip, but
his point was that as long as the car was running OK you could just ignore
the light. And BTW, the Fleetwood runs fine.
