Hi All,
I'm debugging the hunting idle and just cleaned and validated the AAR is working properly on my bench. When checking the voltage in the car I noticed then when the key is turned to the ON position I get a flash of voltage but it drops down to zero instantly and do not notice a constant 12 V when the engine is running. Is this the correct? Thanks, Dan |

There would be a flash of power with the key on and engine off, as the fuel pump only runs for a few seconds with the engine not started to prime the system. Test again with the engine running and you should see 12V all the time at the valve. |

Thank you both, after cleaning it up, I confirmed that it works and is completely closed when the car has warmed up.
