I Took my car to get it scanned regarding all the service engine soon poppin up and my car starting to tremble..
well the reader didnt read my PCM.. and the tech told me that once the service engine light comes on.. it stays on even if the battery cable is disconnected..cause my SES stays on and it comes off... he used two machines to try and read it and it didnt connect.. and i took my car in to get it scanned a year ago at the same place with the same machine.. so it has read my PCM with no problem....
the tech told me it is most likely my PCM has gone bad.. because it cannot be read and it acting up..
anyone know if this could be right???..
anyone know if the PCM is expensive??..
