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 |

One main question I had was could you use one from a 1.8 or 944. YES YOU CAN! despite what the FI sites tell you. I am running one right now. I have been told that some Volvo, Datsun, and other cars run the same type AAR. There is some good info in the link. This site is great for bouncing ideas around and I was grateful for the responses I received. I had AAR questions a while back. I would definitely run one. Get in on cold morning start your car and your idle automatically goes up about 1,000rmps. The AAR simply allows a controlled vacuum leak into the intake, which in turn jacks the idle up. It is a valve that when cold is open and once you turn your key you are (should be) supplying 12v, so after a little bit the valve closes. Simple but effective. To hook this style up you just need small wire connectors 1 wire negative (ground it some where) other wire positive (I have mine going to keyed positive on coil). New style like 914 1.8 or 944 Porsche, Volvo, Datsun, and etc.  NLA 2.0 style  |
