Hey all I have a 1984 eldorado. Was running fine yesterday afternoon and for most of the day. Then i noticed that the service soon light was on and my car would idle very very high and loud. I pulled some trouble codes and i got 88 26 27 88 26 27 88 26 88 7.0. I don't know if the order of the codes has anything to do with anything important or not. I cannot find anywhere a list of these codes. Was wondering if someone could help me out!
