My service soon light is on in my 84 Eldorado, so I read through some threads and figured out how to get error codes from the car by pressing the off and warner buttons. The codes are 19, 23, 26, and 30.
Now, I found that 26 and 30 refer to the idle speed control, so I probably have to get that fixed, right?
So, what do 19 and 23 mean? Any help would be great. The sooner the better, as I'm bringing the car in tomorrow to have one of the axles changed.
