CTS Started Spazzing????
my wife was driving and the car started sputtering and stalled, she restarted and could not go more than 5 miles an hour, then pulled over and shut car off and restarted and it began running ok, except for downshifting erratically. when she got home i took it for a drive and it was totally fine but the check engine light is on, so i scanned codes and this is what i got. C1278, P2101, P1779, P1780, P1795, P0121, P0221. In that order can anyone tell me where to start, i replaced throttle body with a used one at beginning of summer, i cleaned it before installation. I remember having to replace it because of an erratic behavior, but it was different codes back then. Oh almost forgot this is a 2003 cts with a 3.2l
