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 |

Fix it and use it. We just got ours working and it works great. If you cant get it fixed, the ones that come on a 944 will work but you will need to run a ground wire |

Just a follow up on my question about the AAR;
Thank you for the information on the AAR. I used the pbanders link and serviced my AAR. I tried the 'renew' portion of the doc - spraying WD40 into the ports and leaving it upside down. I did this all last week. Yesterday I blew it out with compressed air, and tested it. After about 5 or so minutes, it was warm and I could no longer blow any air through it - so it works! Reinstalled it, installed new hoses to it and connected it back up. The male portion of the connector broke at the base of the wire so I had to solder in a splice and new power connector but all is good. Don't know how it will run yet because I am still installing my serviced fuel injectors and new fuel lines in the engine compartment - but it should be running by this coming weekend. Thanks for the info. Tom '73 2.0 http://members.rennlist.com/pbanders/djetp...tm#troubleshoot Fix it and use it. We just got ours working and it works great.
