diagnosis codes Q?
I did a diagnosis on my ea mpfi and i got codes 12 & 13 which is a faulty ISC, i went to the wreckers and got another one but now its coming up with codes 12, 13 , 16 are ISC a common prob and would it make the car shudder on idle.
12 - ISC solenoid
13 - ISC soleniod
16 - ISc soleniod
Why dose the computer have three codes for the same thing?
