Well I bought a OBD1 code reader for my truck and got alot of codes.
KOEO - 11
Continuous memory - 33 41 63 95
KOER - 21 22 42 13 77 52
Now, I don't have power steering in this truck, so don't know why i got code 52.
And would code 77 mean i have to do the KOER test over again?
So now where to start for the idle problem?
