So I’m trying to pass smog, and I have the codes P2004 and P2008. I know that the codes mean runner control stuck open and runner control circuit open. Vacuum lines appear to be fine so I’m thinking just the solenoid is bad. I am confused, however, as the 2.3 has 2 solenoids right next to each other on top of the intake manifold. Which one would I replace? Will it throw a different code if I switch them around?
