service engine soon light came on, scanned and got code p0108 manifold absolute pressure/barometric pressure sensor circuit input high. Don't know what to check from here, car runs fine, no noticeable difference.

The map sensor vacuum hose may be cracked or blocked, connector loose or the map bad. Try and do a full scan see what it reads as a baro sensor, with key off should read the baro readings for your area.
