Hello everyone,
In going over my car's vacuum lines - waiting for my fuel injectors to be returned from servicing - I decided to replace the hose from the AAR valve to the cold start valve. Then I started to think - a dangerous thing - why do I need the AAR if the cold start valve is disconnected? It currently has no fuel supply so it's not working. Currently my AAR is stuck open. Should I try to free it and reinstall it, or can I just plug the hose to the cold start valve and not bother putting it back? Before I pulled the injectors for service, when my car was running (I am getting this car running again from a 3 year sleep) it had a way high idle ~ 1400rpms - so there's undoubtedly vacuum leak(s) somewhere. Any input is welcome. Thanks! Tom '73 2.0 |

They free-up pretty easily with PB Blaster. You can test befor installation; run a couple of small wires from the battery to the AAR while hold up. You should see the orifice in the AAR close in about 2 minutes.

You should see the orifice in the AAR close in about 2 minutes. I bought a couple of spare AAR's off ebay recently that were in really good shape. Both were still sticky in operation. I inverted them, and flooded the intake port with WD-40 so that it ran out into a rag, then took Q-tips to clean out the ports. I then blew out the remaining WD-40 with compressed air. I then hooked them up to a 12V source and watched the operation to make sure they didn't hang (you can look into the intake port and watch it close). Took a few rounds of cleaning before they both operated smoothly. |

Otherwise, I might be looking for a good used one... Regards, Tom 73 2.0 |
