Thanks. The CEL appears to be related to a leak in the hoses (an emissions focus, a local mechanic told me). They were hesitant to work with aftermarket parts so I have to take it back to the shop it has a history with. The previous owner and I are good friends. I have the records of work, and yes, it is in good condition based on what I was told from a general inspection. Belts were done a year ago.
I am thinking that MAYBE the fact that the car was just sitting in the garage for 6 months, only to be started once a day, may have something to do with it???
