I got the car running last week, but so far I have the following error codes

55 â€“ ECM error
63 â€“ Right bank O2 sensor lean exhaust indicated
64 â€“ Map sensor circuit signal voltage low (High vacuum indicated)

The first time it turned on the code was yesterday after getting on it through third gear (good heavens!!!), then it turned out after I shut the car down and restarted it after an hour (figuring it was a hard code and wouldnâ€™t erase) but the light was out. Drove it home without getting into the throttle. This morning, it turned on the SES light driving down the freeway at cruising speed (70 MPH).

I havenâ€™t cleared the codes yet (via disconnecting the battery or pulling the ecm fuse), but I would like to get the car emissions tested and for that the SES light needs to be out.

Ideas?
