My wife has a 98 Eldo which has the "Service engine soon" light on. It happened after I did a tune up today. I had the MAP sensor off to clean But I think the cause is probably because I had the coil pak disconnected in order to get at the rear plugs and wile this was disconnected I also turned the motor over checking something else. If I disconnect the battery will that get the code off?
