What's the sympton of a bad AAR
Anybody sould help. Would a bad AAR affect the functionality of a fuel pump as the pin# 12 from the 12 pin connector on relay board is connected to AAR and also to the pin# 87 of the fuel pump relay and then goes to the pin#13 of the 14 pin connector of the relay board. Please any help? Thanks |

I don't think so .
It's function is simple . Open / shut valve . When the car is cold at initial startup, it opens the vacuum line so that the car idles high for warm up, after a few minutes (I think 10) I closes and the idle drops to normal. |
