1992 subaru svx automatic

Vehicle is good shape. Assorted minor nicks in the paint. Small dent on the drivers door. Purchased the vehicle as an extra car several years ago from a private seller. Check engine light has been coming on and off since I purchased the car. Took it to the dealer who found debris down inside the venting. It was cleaned out and improved things. Took it back at inspection time and told them about the light. They checked it and said it would some work to remove a number of things to totally clean it out. Was not willing to pay for it, ince they said it only stop the light from coming on and and increase the gas mileage a little. It was affecting a O2 sensor. Been driving it for years now this way. Vehicle can be picked up. No shipping unless buyer arranges it.Certified check or PayPal.
